# LaTeX Research Posters

## Overview

Research posters are a critical medium for scientific communication at conferences, symposia, and academic events. This skill provides comprehensive guidance for creating professional, visually appealing research posters using LaTeX packages. Generate publication-quality posters with proper layout, typography, color schemes, and visual hierarchy.

For poster figure palettes, use the shared scientific palette API and presets
rather than raw colors embedded only in poster guidance. Route palette selection
to `publication-figure-palettes`; route accessibility/export checks to
`scientific-figure-qa`.

## When to Use This Skill

This skill should be used when:
- Creating research posters for conferences, symposia, or poster sessions
- Designing academic posters for university events or thesis defenses
- Preparing visual summaries of research for public engagement
- Converting scientific papers into poster format
- Creating template posters for research groups or departments
- Designing posters that comply with specific conference size requirements (A0, A1, 36×48", etc.)
- Building posters with complex multi-column layouts
- Integrating figures, tables, equations, and citations in poster format

## AI-Powered Visual Element Generation

**STANDARD WORKFLOW: Plan poster visuals before creating the LaTeX poster; use existing evidence figures first and generate new visuals only when needed.**

This is the recommended approach for creating visually compelling posters:
1. Plan all visual elements needed (title, intro, methods, results, conclusions)
2. Generate new elements with a visualization skill only when existing evidence figures are insufficient
3. Assemble generated images in the LaTeX template
4. Add text content around the visuals

**Target: A poster should be visually led, but generated visuals are optional and must serve the evidence and venue, 30-40% text.**

---

### CRITICAL: Preventing Content Overflow

**⚠️ POSTERS MUST NOT HAVE TEXT OR CONTENT CUT OFF AT EDGES.**

**Common Overflow Problems:**
1. **Title/footer text extending beyond page boundaries**
2. **Too many sections crammed into available space**
3. **Figures placed too close to edges**
4. **Text blocks exceeding column widths**

**Prevention Rules:**

**1. Limit Content Sections (MAXIMUM 5-6 sections for A0):**
```
✅ GOOD - 5 sections with room to breathe:
   - Title/Header
   - Introduction/Problem
   - Methods
   - Results (1-2 key findings)
   - Conclusions

❌ BAD - 8+ sections crammed together:
   - Overview, Introduction, Background, Methods, 
   - Results 1, Results 2, Discussion, Conclusions, Future Work
```

**2. Set Safe Margins in LaTeX:**
```latex
% tikzposter - add generous margins
\documentclass[25pt, a0paper, portrait, margin=25mm]{tikzposter}

% baposter - ensure content doesn't touch edges
\begin{poster}{
  columns=3,
  colspacing=2em,           % Space between columns
  headerheight=0.1\textheight,  % Smaller header
  % Leave space at bottom
}
```

**3. Figure Sizing - Never 100% Width:**
```latex
% Leave margins around figures
\includegraphics[width=0.85\linewidth]{figure.png}  % NOT 1.0\linewidth
```

**4. Check for Overflow Before Printing:**
```bash
# Compile and check PDF at 100% zoom
pdflatex poster.tex

# Look for:
# - Text cut off at any edge
# - Content touching page boundaries  
# - Overfull hbox warnings in .log file
grep -i "overfull" poster.log
```

**5. Word Count Limits:**
- **A0 poster**: 300-800 words MAXIMUM
- **Per section**: 50-100 words maximum
- **If you have more content**: Cut it or make a handout

---

### CRITICAL: Poster-Size Font Requirements

**⚠️ ALL text within Visualizations should be poster-readable.**

When generating graphics for posters, you MUST include font size specifications in EVERY prompt. Poster graphics are viewed from 4-6 feet away, so text must be LARGE.

**⚠️ COMMON PROBLEM: Content Overflow and Density**

The #1 issue with AI-generated poster graphics is **TOO MUCH CONTENT**. This causes:
- Text overflow beyond boundaries
- Unreadable small fonts
- Cluttered, overwhelming visuals
- Poor white space usage

**SOLUTION: Generate SIMPLE graphics with MINIMAL content.**

**Prompt requirements when generating new visuals for EVERY poster graphic:**

```
POSTER FORMAT REQUIREMENTS (STRICTLY ENFORCE):
- ABSOLUTE MAXIMUM 3-4 elements per graphic (3 is ideal)
- ABSOLUTE MAXIMUM 10 words total in the entire graphic
- NO complex workflows with 5+ steps (split into 2-3 simple graphics instead)
- NO multi-level nested diagrams (flatten to single level)
- NO case studies with multiple sub-sections (one key point per case)
- ALL text GIANT BOLD (80pt+ for labels, 120pt+ for key numbers)
- High contrast ONLY (dark on white OR white on dark, NO gradients with text)
- MANDATORY 50% white space minimum (half the graphic should be empty)
- Thick lines only (5px+ minimum), large icons (200px+ minimum)
- ONE SINGLE MESSAGE per graphic (not 3 related messages)
```

**⚠️ BEFORE GENERATING: Review your prompt and count elements**
- If your description has 5+ items → STOP. Split into multiple graphics
- If your workflow has 5+ stages → STOP. Show only 3-4 high-level steps
- If your comparison has 4+ methods → STOP. Show only top 3 or Our vs Best Baseline

**Content limits per graphic type (STRICT):**
| Graphic Type | Max Elements | Max Words | Reject If | Good Example |
|--------------|--------------|-----------|-----------|--------------|
| Flowchart | **3-4 boxes MAX** | **8 words** | 5+ stages, nested steps | "DISCOVER → VALIDATE → APPROVE" (3 words) |
| Key findings | **3 items MAX** | **9 words** | 4+ metrics, paragraphs | "95% ACCURATE" "2X FASTER" "FDA READY" (6 words) |
| Comparison chart | **3 bars MAX** | **6 words** | 4+ methods, legend text | "OURS: 95%" "BEST: 85%" (4 words) |
| Case study | **1 case, 3 elements** | **6 words** | Multiple cases, substories | Logo + "18 MONTHS" + "to discovery" (2 words) |
| Timeline | **3-4 points MAX** | **8 words** | Year-by-year detail | "2020 START" "2022 TRIAL" "2024 APPROVED" (6 words) |

**Example - WRONG (7-stage workflow - TOO COMPLEX):**
```bash
# ❌ BAD - This creates tiny unreadable text like the drug discovery poster
python scripts/generate_schematic.py "Drug discovery workflow showing: Stage 1 Target Identification, Stage 2 Molecular Synthesis, Stage 3 Virtual Screening, Stage 4 AI Lead Optimization, Stage 5 Clinical Trial Design, Stage 6 FDA Approval. Include success metrics, timelines, and validation steps for each stage." -o figures/workflow.png
# Result: 7+ stages with tiny text, unreadable from 6 feet - POSTER FAILURE
```

**Example - CORRECT (simplified to 3 key stages):**
```bash
# ✅ GOOD - Same content, split into ONE simple high-level graphic
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' → 'VALIDATE' → 'APPROVE'. Each word in GIANT bold (120pt+). Thick arrows (10px). 60% white space. NO substeps, NO details. 3 words total. Readable from 10 feet." -o figures/workflow_overview.png
# Result: Clean, impactful, readable - can add detail graphics separately if needed
```

**Example - WRONG (complex case studies with multiple sections):**
```bash
# ❌ BAD - Creates cramped unreadable sections
python scripts/generate_schematic.py "Case studies: Insilico Medicine (drug candidate, discovery time, clinical trials), Recursion Pharma (platform, methodology, results), Exscientia (drug candidates, FDA status, timeline). Include company logos, metrics, and outcomes." -o figures/cases.png
# Result: 3 case studies with 4+ elements each = 12+ total elements, tiny text
```

**Example - CORRECT (one case study, one key metric):**
```bash
# ✅ GOOD - Show ONE case with ONE key number
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case study card: Company logo (large), '18 MONTHS' in GIANT text (150pt), 'to discovery' below (60pt). 3 elements total: logo + number + caption. 50% white space. Readable from 10 feet." -o figures/case_single.png
# Result: Clear, readable, impactful. Make 3 separate graphics if you need 3 cases.
```

**Example - WRONG (key findings too complex):**
```bash
# BAD - too many items, too much detail
python scripts/generate_schematic.py "Key findings showing 8 metrics: accuracy 95%, precision 92%, recall 94%, F1 0.93, AUC 0.97, training time 2.3 hours, inference 50ms, model size 145MB with comparison to 5 baseline methods" -o figures/findings.png
# Result: Cramped graphic with tiny numbers
```

**Example - CORRECT (key findings simple):**
```bash
# GOOD - only 3 key items, giant numbers
python scripts/generate_schematic.py "POSTER FORMAT for A0. KEY FINDINGS with ONLY 3 large cards. Card 1: '95%' in GIANT text (120pt) with 'ACCURACY' below (48pt). Card 2: '2X' in GIANT text with 'FASTER' below. Card 3: checkmark icon with 'VALIDATED' in large text. 50% white space. High contrast colors. NO other text or details." -o figures/findings.png
# Result: Bold, readable impact statement
```

**Font size reference for poster prompts:**
| Element | Minimum Size | Prompt Keywords |
|---------|--------------|-----------------|
| Main numbers/metrics | 72pt+ | "huge", "very large", "giant", "poster-size" |
| Section titles | 60pt+ | "large bold", "prominent" |
| Labels/captions | 36pt+ | "readable from 6 feet", "clear labels" |
| Body text | 24pt+ | "poster-readable", "large text" |

**Always include in prompts:**
- "POSTER FORMAT" or "for A0 poster" or "readable from 6 feet"
- "VERY LARGE TEXT" or "huge bold fonts"
- Specific text that should appear (so it's baked into the image)
- "minimal text, maximum impact"
- "high contrast" for readability
- "generous margins" and "no text near edges"

---

### CRITICAL: AI-Generated Graphic Sizing

**⚠️ Each AI-generated graphic should focus on ONE concept with MINIMAL content.**

**Problem**: Generating complex diagrams with many elements leads to small text.

**Solution**: Generate SIMPLE graphics with FEW elements and LARGE text.

**Example - WRONG (too complex, text will be small):**
```bash
# BAD - too many elements in one graphic
python scripts/generate_schematic.py "Complete ML pipeline showing data collection, 
preprocessing with 5 steps, feature engineering with 8 techniques, model training 
with hyperparameter tuning, validation with cross-validation, and deployment with 
monitoring. Include all labels and descriptions." -o figures/pipeline.png
```

**Example - CORRECT (simple, focused, large text):**
```bash
# GOOD - split into multiple simple graphics with large text

# Graphic 1: High-level overview (3-4 elements max)
python scripts/generate_schematic.py "POSTER FORMAT for A0: Simple 4-step pipeline. 
Four large boxes: DATA → PROCESS → MODEL → RESULTS. 
GIANT labels (80pt+), thick arrows, lots of white space. 
Only 4 words total. Readable from 8 feet." -o figures/overview.png

# Graphic 2: Key result (1 metric highlighted)
python scripts/generate_schematic.py "POSTER FORMAT for A0: Single key metric display.
Giant '95%' text (150pt+) with 'ACCURACY' below (60pt+).
Checkmark icon. Minimal design, high contrast.
Readable from 10 feet." -o figures/accuracy.png
```

**Rules for AI-generated poster graphics:**
| Rule | Limit | Reason |
|------|-------|--------|
| **Elements per graphic** | 3-5 maximum | More elements = smaller text |
| **Words per graphic** | 10-15 maximum | Minimal text = larger fonts |
| **Flowchart steps** | 4-5 maximum | Keeps labels readable |
| **Chart categories** | 3-4 maximum | Prevents crowding |
| **Nested levels** | 1-2 maximum | Avoids complexity |

**Split complex content into multiple simple graphics:**
```
Instead of 1 complex diagram with 12 elements:
→ Create 3 simple diagrams with 4 elements each
→ Each graphic can have LARGER text
→ Arrange in poster with clear visual flow
```

---

### Step 0: MANDATORY Pre-Generation Review (DO THIS FIRST)

**⚠️ BEFORE generating ANY graphics, review your content plan:**

**For EACH planned graphic, ask these questions:**
1. **Element count**: Can I describe this in 3-4 items or less?
   - ❌ NO → Simplify or split into multiple graphics
   - ✅ YES → Continue

2. **Complexity check**: Is this a multi-stage workflow (5+ steps) or nested diagram?
   - ❌ YES → Flatten to 3-4 high-level steps only
   - ✅ NO → Continue

3. **Word count**: Can I describe all text in 10 words or less?
   - ❌ NO → Cut text, use single-word labels
   - ✅ YES → Continue

4. **Message clarity**: Does this graphic convey ONE clear message?
   - ❌ NO → Split into multiple focused graphics
   - ✅ YES → Continue to generation

**Common patterns that ALWAYS fail (reject these):**
- "Show stages 1 through 7..." → Split into high-level overview (3 stages) + detail graphics
- "Multiple case studies..." → One case per graphic
- "Timeline from 2015 to 2024 with annual milestones..." → Show only 3-4 key years
- "Comparison of 6 methods..." → Show only top 3 or Our method vs Best baseline
- "Architecture with all layers and connections..." → High-level only (3-4 components)

### Step 1: Plan Your Poster Elements

After passing the pre-generation review, identify visual elements needed:

1. **Title Block** - Stylized title with institutional branding (optional - can be LaTeX text)
2. **Introduction Graphic** - Conceptual overview (3 elements max)
3. **Methods Diagram** - High-level workflow (3-4 steps max)
4. **Results Figures** - Key findings (3 metrics max per figure, may need 2-3 separate figures)
5. **Conclusion Graphic** - Summary visual (3 takeaways max)
6. **Supplementary Icons** - Simple icons, QR codes, logos (minimal)

### Step 2: Generate Each Element (After Pre-Generation Review)

**⚠️ CRITICAL: Review Step 0 checklist before proceeding.**

Use the appropriate tool for each element type:

**For Schematics and Diagrams (scientific-schematics):**
```bash
# Create figures directory
mkdir -p figures

# Drug discovery workflow - HIGH-LEVEL ONLY, 3 stages
# BAD: "Stage 1: Target ID, Stage 2: Molecular Synthesis, Stage 3: Virtual Screening, Stage 4: AI Lead Opt..."
# GOOD: Collapse to 3 mega-stages
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' (120pt bold) → 'VALIDATE' (120pt bold) → 'APPROVE' (120pt bold). Thick arrows (10px). 60% white space. ONLY these 3 words. NO substeps. Readable from 12 feet." -o figures/workflow_simple.png

# System architecture - MAXIMUM 3 components
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-component stack: 'DATA' box (120pt) → 'AI MODEL' box (120pt) → 'PREDICTION' box (120pt). Thick vertical arrows. 60% white space. 3 words only. Readable from 12 feet." -o figures/architecture.png

# Timeline - ONLY 3 key milestones (not year-by-year)
# BAD: "2018, 2019, 2020, 2021, 2022, 2023, 2024 with events"
# GOOD: Only 3 breakthrough moments
python scripts/generate_schematic.py "POSTER FORMAT for A0. Timeline with ONLY 3 points: '2018' + icon, '2021' + icon, '2024' + icon. GIANT years (120pt). Large icons. 60% white space. NO connecting lines or details. Readable from 12 feet." -o figures/timeline.png

# Case study - ONE case, ONE key metric
# BAD: "3 case studies: Insilico (details), Recursion (details), Exscientia (details)"
# GOOD: ONE case with ONE number
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case study: Large logo + '18 MONTHS' (150pt bold) + 'to discovery' (60pt). 3 elements total. 60% white space. Readable from 12 feet." -o figures/case1.png

# If you need 3 cases → make 3 separate simple graphics (not one complex graphic)
```

**For Stylized Blocks and Graphics:**
```bash
# Title block - SIMPLE
python scripts/generate_schematic.py "POSTER FORMAT for A0. Title block: 'ML FOR DRUG DISCOVERY' in HUGE bold text (120pt+). Dark blue background. ONE subtle icon. NO other text. 40% white space. Readable from 15 feet." -o figures/title_block.png

# Introduction visual - SIMPLE, 3 elements only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE problem visual with ONLY 3 icons: drug icon, arrow, target icon. ONE label per icon (80pt+). 50% white space. NO detailed text. Readable from 8 feet." -o figures/intro_visual.png

# Conclusion/summary - ONLY 3 items, GIANT numbers
python scripts/generate_schematic.py "POSTER FORMAT for A0. KEY FINDINGS with EXACTLY 3 cards only. Card 1: '95%' (150pt font) with 'ACCURACY' (60pt). Card 2: '2X' (150pt) with 'FASTER' (60pt). Card 3: checkmark icon with 'READY' (60pt). 50% white space. NO other text. Readable from 10 feet." -o figures/conclusions_graphic.png

# Background visual - SIMPLE, 3 icons only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE visual with ONLY 3 large icons in a row: problem icon → challenge icon → impact icon. ONE word label each (80pt+). 50% white space. NO detailed text. Readable from 8 feet." -o figures/background_visual.png
```

**For Data Visualizations - SIMPLE, 3 bars max:**
```bash
# SIMPLE chart with ONLY 3 bars, GIANT labels
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE bar chart with ONLY 3 bars: BASELINE (70%), EXISTING (85%), OURS (95%). GIANT percentage labels ON the bars (100pt+). NO axis labels, NO legend, NO gridlines. Our bar highlighted in different color. 40% white space. Readable from 8 feet." -o figures/comparison_chart.png
```

### Step 2b: MANDATORY Post-Generation Review (Before Assembly)

**⚠️ CRITICAL: Review EVERY generated graphic before adding to poster.**

**For each generated figure, open at 25% zoom and check:**

1. **✅ PASS criteria (all must be true):**
   - Can read ALL text clearly at 25% zoom
   - Count elements: 3-4 or fewer
   - White space: 50%+ of image is empty
   - Simple enough to understand in 2 seconds
   - NOT a complex workflow with 5+ stages
   - NOT multiple nested sections

2. **❌ FAIL criteria (regenerate if ANY are true):**
   - Text is small or hard to read at 25% zoom → REGENERATE with "150pt+" fonts
   - More than 4 elements → REGENERATE with "ONLY 3 elements"
   - Less than 50% white space → REGENERATE with "60% white space"
   - Complex multi-stage workflow → SPLIT into 2-3 simple graphics
   - Multiple case studies cramped together → SPLIT into separate graphics
   - Takes more than 3 seconds to understand → SIMPLIFY and regenerate

**Common failures and fixes:**
- "7-stage workflow with tiny text" → Regenerate as "3 high-level stages only"
- "3 case studies in one graphic" → Generate 3 separate simple graphics
- "Timeline with 8 years" → Regenerate with "ONLY 3 key milestones"
- "Comparison of 5 methods" → Regenerate with "ONLY Our method vs Best baseline (2 bars)"

**DO NOT PROCEED to assembly if ANY graphic fails the checks above.**

### Step 3: Assemble in LaTeX Template

After all figures pass the post-generation review, include them in your poster template:

**tikzposter example:**
```latex
\documentclass[25pt, a0paper, portrait]{tikzposter}

\begin{document}

\maketitle

\begin{columns}
\column{0.5}

\block{Introduction}{
  \centering
  \includegraphics[width=0.85\linewidth]{figures/intro_visual.png}
  
  \vspace{0.5em}
  Brief context text here (2-3 sentences max).
}

\block{Methods}{
  \centering
  \includegraphics[width=0.9\linewidth]{figures/methods_flowchart.png}
}

\column{0.5}

\block{Results}{
  \begin{minipage}{0.48\linewidth}
    \centering
    \includegraphics[width=\linewidth]{figures/result_1.png}
  \end{minipage}
  \hfill
  \begin{minipage}{0.48\linewidth}
    \centering
    \includegraphics[width=\linewidth]{figures/result_2.png}
  \end{minipage}
  
  \vspace{0.5em}
  Key findings in 3-4 bullet points.
}

\block{Conclusions}{
  \centering
  \includegraphics[width=0.8\linewidth]{figures/conclusions_graphic.png}
}

\end{columns}

\end{document}
```

**baposter example:**
```latex
\headerbox{Methods}{name=methods,column=0,row=0}{
  \centering
  \includegraphics[width=0.95\linewidth]{figures/methods_flowchart.png}
}

\headerbox{Results}{name=results,column=1,row=0}{
  \includegraphics[width=\linewidth]{figures/comparison_chart.png}
  \vspace{0.3em}
  
  Key finding: Our method achieves 92% accuracy.
}
```

### Example: Complete Poster Generation Workflow

**Full workflow with ALL quality checks:**

```bash
# STEP 0: Pre-Generation Review (MANDATORY)
# Content plan: Drug discovery poster
# - Workflow: 7 stages → ❌ TOO MANY → Reduce to 3 mega-stages ✅
# - 3 case studies → ❌ TOO MANY → One case per graphic (make 3 graphics) ✅
# - Timeline 2018-2024 → ❌ TOO DETAILED → Only 3 key years ✅

# STEP 1: Create figures directory
mkdir -p figures

# STEP 2: Generate ULTRA-SIMPLE graphics with strict limits

# Workflow - HIGH-LEVEL ONLY (collapsed from 7 stages to 3)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' → 'VALIDATE' → 'APPROVE'. Each word 120pt+ bold. Thick arrows (10px). 60% white space. ONLY 3 words total. Readable from 12 feet." -o figures/workflow.png

# Case study 1 - ONE case, ONE metric (will make 3 separate graphics)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + '18 MONTHS' (150pt bold) + 'to drug discovery' (60pt). 3 elements only. 60% white space. Readable from 12 feet." -o figures/case1.png

python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + '95% SUCCESS' (150pt bold) + 'in trials' (60pt). 3 elements only. 60% white space." -o figures/case2.png

python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + 'FDA APPROVED' (150pt bold) + '2024' (60pt). 3 elements only. 60% white space." -o figures/case3.png

# Timeline - ONLY 3 key years (not 7 years)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONLY 3 years: '2018' (150pt) + icon, '2021' (150pt) + icon, '2024' (150pt) + icon. Large icons. 60% white space. NO lines or details. Readable from 12 feet." -o figures/timeline.png

# Results - ONLY 2 bars (our method vs best baseline, not 5 methods)
python scripts/generate_schematic.py "POSTER FORMAT for A0. TWO bars only: 'BASELINE 70%' and 'OURS 95%' (highlighted). GIANT percentages (150pt) ON bars. NO axis, NO legend. 60% white space. Readable from 12 feet." -o figures/results.png

# STEP 2b: Post-Generation Review (MANDATORY)
# Open each figure at 25% zoom:
# ✅ workflow.png: 3 elements, text readable, 60% white - PASS
# ✅ case1.png: 3 elements, giant numbers, clean - PASS
# ✅ case2.png: 3 elements, giant numbers, clean - PASS  
# ✅ case3.png: 3 elements, giant numbers, clean - PASS
# ✅ timeline.png: 3 elements, readable, simple - PASS
# ✅ results.png: 2 bars, giant percentages, clear - PASS
# ALL PASS → Proceed to assembly

# STEP 3: Compile LaTeX poster
pdflatex poster.tex

# STEP 4: PDF Overflow Check (see Section 11)
grep "Overfull" poster.log
# Open at 100% and check all 4 edges
```

**If ANY graphic fails Step 2b review:**
- Too many elements → Regenerate with "ONLY 3 elements"
- Small text → Regenerate with "150pt+" or "GIANT BOLD (150pt+)"
- Cluttered → Regenerate with "60% white space" and "ULTRA-SIMPLE"
- Complex workflow → SPLIT into multiple simple 3-element graphics

### Visual Element Guidelines

**⚠️ CRITICAL: Each graphic must have ONE message and MAXIMUM 3-4 elements.**

**ABSOLUTE LIMITS - These are NOT guidelines, these are HARD LIMITS:**
- **MAXIMUM 3-4 elements** per graphic (3 is ideal)
- **MAXIMUM 10 words** total per graphic
- **MINIMUM 50% white space** (60% is better)
- **MINIMUM 120pt** for key numbers/metrics
- **MINIMUM 80pt** for labels

**For each poster section - STRICT requirements:**

| Section | Max Elements | Max Words | Example Prompt (REQUIRED PATTERN) |
|---------|--------------|-----------|-------------------------------------|
| **Introduction** | 3 icons | 6 words | "POSTER FORMAT for A0: ULTRA-SIMPLE 3 icons: [icon1] [icon2] [icon3]. ONE WORD labels (100pt bold). 60% white space. 3 words total." |
| **Methods** | 3 boxes | 6 words | "POSTER FORMAT for A0: ULTRA-SIMPLE 3-box workflow: 'STEP1' → 'STEP2' → 'STEP3'. GIANT labels (120pt+). 60% white space. 3 words only." |
| **Results** | 2-3 bars | 6 words | "POSTER FORMAT for A0: TWO bars: 'BASELINE 70%' 'OURS 95%'. GIANT percentages (150pt+) ON bars. NO axis. 60% white space." |
| **Conclusions** | 3 cards | 9 words | "POSTER FORMAT for A0: THREE cards: '95%' (150pt) 'ACCURATE', '2X' (150pt) 'FASTER', checkmark 'READY'. 60% white space." |
| **Case Study** | 3 elements | 5 words | "POSTER FORMAT for A0: ONE case: logo + '18 MONTHS' (150pt) + 'to discovery' (60pt). 60% white space." |
| **Timeline** | 3 points | 3 words | "POSTER FORMAT for A0: THREE years only: '2018' '2021' '2024' (150pt each). Large icons. 60% white space. NO details." |

**MANDATORY prompt elements (ALL required, NO exceptions):**
1. **"POSTER FORMAT for A0"** - MUST be first
2. **"ULTRA-SIMPLE"** or **"ONLY X elements"** - content limit
3. **"GIANT (120pt+)"** or specific font sizes - readability
4. **"60% white space"** - mandatory breathing room
5. **"readable from 10-12 feet"** - viewing distance
6. **Exact count** of words/elements - "3 words total" or "ONLY 3 icons"

**PATTERNS THAT ALWAYS FAIL (REJECT IMMEDIATELY):**
- ❌ "7-stage drug discovery workflow" → Split to "3 mega-stages"
- ❌ "Timeline from 2015-2024 with annual updates" → "ONLY 3 key years"
- ❌ "3 case studies with details" → Make 3 separate simple graphics
- ❌ "Comparison of 5 methods with metrics" → "ONLY 2: ours vs best"
- ❌ "Complete architecture showing all layers" → "3 components only"
- ❌ "Show stages 1,2,3,4,5,6" → "3 high-level stages"

**PATTERNS THAT WORK:**
- ✅ "3 mega-stages collapsed from 7" → Proper simplification
- ✅ "ONE case with ONE metric" → Will make multiple if needed
- ✅ "ONLY 3 milestones" → Selective, focused

- **Block-based layouts**: Flexible arrangement of content blocks
- **Z-pattern flow**: Guide readers through content logically
- **Visual hierarchy**: Use size, color, and spacing to emphasize key points

### 3. Design Principles for Research Posters

Apply evidence-based design principles for maximum impact. For detailed design guidance, refer to `references/poster_design_principles.md`.

**Typography**:
- Title: 72-120pt for visibility from distance
- Section headers: 48-72pt
- Body text: 24-36pt minimum for readability from 4-6 feet
- Use sans-serif fonts (Arial, Helvetica, Calibri) for clarity
- Limit to 2-3 font families maximum

**Color and Contrast**:
- Use high-contrast color schemes for readability
- Institutional color palettes for branding
- Color-blind friendly palettes (avoid red-green combinations)
- White space is active space—don't overcrowd

**Visual Elements**:
- High-resolution figures (300 DPI minimum for print)
- Large, clear labels on all figures
- Consistent figure styling throughout
- Strategic use of icons and graphics
- Balance text with visual content (40-50% visual recommended)

**Content Guidelines**:
- **Less is more**: 300-800 words total recommended
- Bullet points over paragraphs for scannability
- Clear, concise messaging
- Self-explanatory figures with minimal text explanation
- QR codes for supplementary materials or online resources

### 4. Standard Poster Sizes

Support for international and conference-specific poster dimensions:

**International Standards**:
- A0 (841 × 1189 mm / 33.1 × 46.8 inches) - Most common European standard
- A1 (594 × 841 mm / 23.4 × 33.1 inches) - Smaller format
- A2 (420 × 594 mm / 16.5 × 23.4 inches) - Compact posters

**North American Standards**:
- 36 × 48 inches (914 × 1219 mm) - Common US conference size
- 42 × 56 inches (1067 × 1422 mm) - Large format
- 48 × 72 inches (1219 × 1829 mm) - Extra large

**Orientation**:
- Portrait (vertical) - Most common, traditional
- Landscape (horizontal) - Better for wide content, timelines

### 5. Package-Specific Templates

Provide ready-to-use templates for each major package. Templates available in `assets/` directory.

**beamerposter Templates**:
- `beamerposter_classic.tex` - Traditional academic style
- `beamerposter_modern.tex` - Clean, minimal design
- `beamerposter_colorful.tex` - Vibrant theme with blocks

**tikzposter Templates**:
- `tikzposter_default.tex` - Standard tikzposter layout

**baposter Templates**:
- `baposter_portrait.tex` - Classic portrait layout
- `baposter_landscape.tex` - Landscape multi-column
- `baposter_minimal.tex` - Minimalist design

### 6. Figure and Image Integration

Optimize visual content for poster presentations:

**Best Practices**:
- Use vector graphics (PDF, SVG) when possible for scalability
- Raster images: minimum 300 DPI at final print size
- Consistent image styling (borders, captions, sizes)
- Group related figures together
- Use subfigures for comparisons

**LaTeX Figure Commands**:
```latex
% Include graphics package
\usepackage{graphicx}

% Simple figure
\includegraphics[width=0.8\linewidth]{figure.pdf}

% Figure with caption in tikzposter
\block{Results}{
  \begin{tikzfigure}
    \includegraphics[width=0.9\linewidth]{results.png}
  \end{tikzfigure}
}

% Multiple subfigures
\usepackage{subcaption}
\begin{figure}
  \begin{subfigure}{0.48\linewidth}
    \includegraphics[width=\linewidth]{fig1.pdf}
    \caption{Condition A}
  \end{subfigure}
  \begin{subfigure}{0.48\linewidth}
    \includegraphics[width=\linewidth]{fig2.pdf}
    \caption{Condition B}
  \end{subfigure}
\end{figure}
```

### 7. Color Schemes and Themes

Provide professional color palettes for various contexts:

**Academic Institution Colors**:
- Match university or department branding
- Use official color codes (RGB, CMYK, or LaTeX color definitions)

**Scientific Color Palettes** (color-blind friendly):
- Use `palette/scientific-figure-palettes.json` or the
  `scientific-visualization` plugin shared palette copy as the canonical source.
- Use `python scripts/palette.py snippet <palette-id> --target latex` to generate
  `\definecolor` commands.
- Prefer `okabe_ito` for categorical poster figures, `viridis`/`cividis` for
  continuous heatmaps, and `RdBu`/`BrBG`/`PuOr` for centered diverging data.

**Package-Specific Theme Selection**:

**beamerposter**:
```latex
\usetheme{Berlin}
\usecolortheme{beaver}
```

**tikzposter**:
```latex
\usetheme{Rays}
\usecolorstyle{Denmark}
```

**baposter**:
```latex
\begin{poster}{
  background=plain,
  bgColorOne=white,
  headerColorOne=blue!70,
  textborder=rounded
}
```

### 8. Typography and Text Formatting

Ensure readability and visual appeal:

**Font Selection**:
```latex
% Sans-serif fonts recommended for posters
\usepackage{helvet}      % Helvetica
\usepackage{avant}       % Avant Garde
\usepackage{sfmath}      % Sans-serif math fonts

% Set default to sans-serif
\renewcommand{\familydefault}{\sfdefault}
```

**Text Sizing**:
```latex
% Adjust text sizes for visibility
\setbeamerfont{title}{size=\VeryHuge}
\setbeamerfont{author}{size=\Large}
\setbeamerfont{institute}{size=\normalsize}
```

**Emphasis and Highlighting**:
- Use bold for key terms: `\textbf{important}`
- Color highlights sparingly: `\textcolor{blue}{highlight}`
- Boxes for critical information
- Avoid italics (harder to read from distance)

### 9. QR Codes and Interactive Elements

Enhance poster interactivity for modern conferences:

**QR Code Integration**:
```latex
\usepackage{qrcode}

% Link to paper, code repository, or supplementary materials
\qrcode[height=2cm]{https://github.com/username/project}

% QR code with caption
\begin{center}
  \qrcode[height=3cm]{https://doi.org/10.1234/paper}\\
  \small Scan for full paper
\end{center}
```

**Digital Enhancements**:
- Link to GitHub repositories for code
- Link to video presentations or demos
- Link to interactive web visualizations
- Link to supplementary data or appendices

### 10. Compilation and Output

Generate high-quality PDF output for printing or digital display:

**Compilation Commands**:
```bash
# Basic compilation
pdflatex poster.tex

# With bibliography
pdflatex poster.tex
bibtex poster
pdflatex poster.tex
pdflatex poster.tex

# For beamer-based posters
lualatex poster.tex  # Better font support
xelatex poster.tex   # Unicode and modern fonts
```

**Ensuring Full Page Coverage**:

Posters should use the entire page without excessive margins. Configure packages correctly:

**beamerposter - Full Page Setup**:
```latex
\documentclass[final,t]{beamer}
\usepackage[size=a0,scale=1.4,orientation=portrait]{beamerposter}

% Remove default beamer margins
\setbeamersize{text margin left=0mm, text margin right=0mm}

% Use geometry for precise control
\usepackage[margin=10mm]{geometry}  % 10mm margins all around

% Remove navigation symbols
\setbeamertemplate{navigation symbols}{}

% Remove footline and headline if not needed
\setbeamertemplate{footline}{}
\setbeamertemplate{headline}{}
```

**tikzposter - Full Page Setup**:
```latex
\documentclass[
  25pt,                      % Font scaling
  a0paper,                   % Paper size
  portrait,                  % Orientation
  margin=10mm,               % Outer margins (minimal)
  innermargin=15mm,          % Space inside blocks
  blockverticalspace=15mm,   % Space between blocks
  colspace=15mm,             % Space between columns
  subcolspace=8mm            % Space between subcolumns
]{tikzposter}

% This ensures content fills the page
```

**baposter - Full Page Setup**:
```latex
\documentclass[a0paper,portrait,fontscale=0.285]{baposter}

\begin{poster}{
  grid=false,
  columns=3,
  colspacing=1.5em,          % Space between columns
  eyecatcher=true,
  background=plain,
  bgColorOne=white,
  borderColor=blue!50,
  headerheight=0.12\textheight,  % 12% for header
  textborder=roundedleft,
  headerborder=closed,
  boxheaderheight=2em        % Consistent box header heights
}
% Content here
\end{poster}
```

**Common Issues and Fixes**:

**Problem**: Large white margins around poster
```latex
% Fix for beamerposter
\setbeamersize{text margin left=5mm, text margin right=5mm}

% Fix for tikzposter
\documentclass[..., margin=5mm, innermargin=10mm]{tikzposter}

% Fix for baposter - adjust in document class
\documentclass[a0paper, margin=5mm]{baposter}
```

**Problem**: Content doesn't fill vertical space
```latex
% Use \vfill between sections to distribute space
\block{Introduction}{...}
\vfill
\block{Methods}{...}
\vfill
\block{Results}{...}

% Or manually adjust block spacing
\vspace{1cm}  % Add space between specific blocks
```

**Problem**: Poster extends beyond page boundaries
```latex
% Check total width calculation
% For 3 columns with spacing:
% Total = 3×columnwidth + 2×colspace + 2×margins
% Ensure this equals \paperwidth

% Debug by adding visible page boundary
\usepackage{eso-pic}
\AddToShipoutPictureBG{
  \AtPageLowerLeft{
    \put(0,0){\framebox(\LenToUnit{\paperwidth},\LenToUnit{\paperheight}){}}
  }
}
```

**Print Preparation**:
- Generate PDF/X-1a for professional printing
- Embed all fonts
- Convert colors to CMYK if required
- Check resolution of all images (minimum 300 DPI)
- Add bleed area if required by printer (usually 3-5mm)
- Verify page size matches requirements exactly

**Digital Display**:
- RGB color space for screen display
- Optimize file size for email/web
- Test readability on different screens

### 11. PDF Review and Quality Control

**CRITICAL**: Always review the generated PDF before printing or presenting. Use this systematic checklist:

**Step 1: Page Size Verification**
```bash
# Check PDF dimensions (should match poster size exactly)
pdfinfo poster.pdf | grep "Page size"

# Expected outputs:
# A0: 2384 x 3370 points (841 x 1189 mm)
# 36x48": 2592 x 3456 points
# A1: 1684 x 2384 points (594 x 841 mm)
```

**Step 2: OVERFLOW CHECK (CRITICAL) - DO THIS IMMEDIATELY AFTER COMPILATION**

**⚠️ THIS IS THE #1 CAUSE OF POSTER FAILURES. Check BEFORE proceeding.**

**Step 2a: Check LaTeX Log File**
```bash
# Check for overflow warnings (these are ERRORS, not suggestions)
grep -i "overfull\|underfull\|badbox" poster.log

# ANY "Overfull" warning = content is cut off or extending beyond boundaries
# FIX ALL OF THESE before proceeding
```

**Common overflow warnings and what they mean:**
- `Overfull \hbox (15.2pt too wide)` → Text or graphic is 15.2pt wider than column
- `Overfull \vbox (23.5pt too high)` → Content is 23.5pt taller than available space
- `Badbox` → LaTeX struggling to fit content within boundaries

**Step 2b: Visual Edge Inspection (100% zoom in PDF viewer)**

**Check ALL FOUR EDGES systematically:**

1. **TOP EDGE:**
   - [ ] Title completely visible (not cut off)
   - [ ] Author names fully visible
   - [ ] No graphics touching top margin
   - [ ] Header content within safe zone

2. **BOTTOM EDGE:**
   - [ ] References fully visible (not cut off)
   - [ ] Acknowledgments complete
   - [ ] Contact info readable
   - [ ] No graphics cut off at bottom

3. **LEFT EDGE:**
   - [ ] No text touching left margin
   - [ ] All bullet points fully visible
   - [ ] Graphics have left margin (not bleeding off)
   - [ ] Column content within bounds

4. **RIGHT EDGE:**
   - [ ] No text extending beyond right margin
   - [ ] Graphics not cut off on right
   - [ ] Column content stays within bounds
   - [ ] QR codes fully visible

5. **BETWEEN COLUMNS:**
   - [ ] Content stays within individual columns
   - [ ] No text bleeding into adjacent columns
   - [ ] Figures respect column boundaries

**If ANY check fails, you have overflow. FIX IMMEDIATELY before continuing:**

**Fix hierarchy (try in order):**
1. **Check AI-generated graphics first:**
   - Are they too complex (5+ elements)? → Regenerate simpler
   - Do they have tiny text? → Regenerate with "150pt+" fonts
   - Are there too many? → Reduce number of figures

2. **Reduce sections:**
   - More than 5-6 sections? → Combine or remove
   - Example: Merge "Discussion"
