# 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.

## 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

## Boundary

This skill owns poster layout and LaTeX poster production. It can place existing figures and specify visual space allocation, but it does not generate diagrams, plots, data figures, or presentation decks, and it must not require a separate visual specialist as part of normal poster work.

- **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

- `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):
- Viridis: Professional gradient from purple to yellow
- ColorBrewer: Research-tested palettes for data visualization
- IBM Color Blind Safe: Accessible corporate palette

**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: Visual Inspection Checklist**

Open PDF at 100% zoom and check:

**Layout and Spacing**:
- [ ] Content fills entire page (no large white margins)
- [ ] Consistent spacing between columns
- [ ] Consistent spacing between blocks/sections

**Technical Quality**:
- [ ] No LaTeX compilation warnings in important areas
- [ ] All citations resolved (no [?] marks)
- [ ] All cross-references working
- [ ] Page boundaries correct (no content cut off)

**Step 3: Reduced-Scale Print Test**

**Essential Pre-Printing Test**:
```bash
# Create reduced-size test print (25% of final size)
# This simulates viewing full poster from ~8-10 feet

# For A0 poster, print on A4 paper (24.7% scale)
# For 36x48" poster, print on letter paper (~25% scale)
```

**Print Test Checklist**:
- [ ] Title readable from 6 feet away
- [ ] Section headers readable from 4 feet away
- [ ] Body text readable from 2 feet away
- [ ] Figures clear and understandable
- [ ] Colors printed accurately
- [ ] No obvious design flaws

**Step 4: Digital Quality Checks**

**Font Embedding Verification**:
```bash
# Check that all fonts are embedded (required for printing)
pdffonts poster.pdf

# All fonts should show "yes" in "emb" column
# If any show "no", recompile with:
pdflatex -dEmbedAllFonts=true poster.tex
```

**Image Resolution Check**:
```bash
# Extract image information
pdfimages -list poster.pdf

# Check that all images are at least 300 DPI
# Formula: DPI = pixels / (inches in poster)
# For A0 width (33.1"): 300 DPI = 9930 pixels minimum
```

**File Size Optimization**:
```bash
# For email/web, compress if needed (>50MB)
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 \
   -dPDFSETTINGS=/printer -dNOPAUSE -dQUIET -dBATCH \
   -sOutputFile=poster_compressed.pdf poster.pdf

# For printing, keep original (no compression)
```

**Step 5: Accessibility Check**

**Color Contrast Verification**:
- [ ] Text-background contrast ratio ≥ 4.5:1 (WCAG AA)
- [ ] Important elements contrast ratio ≥ 7:1 (WCAG AAA)
- Test online: https://webaim.org/resources/contrastchecker/

**Color Blindness Simulation**:
- [ ] View PDF through color blindness simulator
- [ ] Information not lost with red-green simulation
- [ ] Use Coblis (color-blindness.com) or similar tool

**Step 6: Content Proofreading**

**Systematic Review**:
- [ ] Spell-check all text
- [ ] Verify all author names and affiliations
- [ ] Check all numbers and statistics for accuracy
- [ ] Confirm all citations are correct
- [ ] Review figure labels and captions
- [ ] Check for typos in headers and titles

**Peer Review**:
- [ ] Ask colleague to review poster
- [ ] 30-second test: Can they identify main message?
- [ ] 5-minute review: Do they understand conclusions?
- [ ] Note any confusing elements

**Step 7: Technical Validation**

**LaTeX Compilation Log Review**:
```bash
# Check for warnings in .log file
grep -i "warning\|error\|overfull\|underfull" poster.log

# Common issues to fix:
# - Overfull hbox: Text extending beyond margins
# - Underfull hbox: Excessive spacing
# - Missing references: Citations not resolved
# - Missing figures: Image files not found
```

**Fix Common Warnings**:
```latex
% Overfull hbox (text too wide)
\usepackage{microtype}  % Better spacing
\sloppy  % Allow slightly looser spacing
\hyphenation{long-word}  % Manual hyphenation

% Missing fonts
\usepackage[T1]{fontenc}  % Better font encoding

% Image not found
% Ensure paths are correct and files exist
\graphicspath{{./figures/}{./images/}}
```

**Step 8: Final Pre-Print Checklist**

## Workflow for Poster Creation

### Stage 1: Planning and Content Development

1. **Determine poster requirements**:
   - Conference size specifications (A0, 36×48", etc.)
   - Orientation (portrait vs. landscape)
   - Submission deadlines and format requirements

2. **Develop content outline**:
   - Identify 1-3 core messages
   - Select key figures (typically 3-6 main visuals)
   - Draft concise text for each section (bullet points preferred)
   - Aim for 300-800 words total

3. **Choose LaTeX package**:
   - beamerposter: If familiar with Beamer, need institutional themes
   - tikzposter: For modern, colorful designs with flexibility
   - baposter: For structured, professional multi-column layouts

### Stage 2: Design and Layout

1. **Select or create template**:
   - Start with provided templates in `assets/`
   - Customize color scheme to match branding
   - Configure page size and orientation

2. **Design layout structure**:
   - Plan column structure (2, 3, or 4 columns)
   - Map content flow (typically left-to-right, top-to-bottom)
   - Allocate space for title (10-15%), content (70-80%), footer (5-10%)

3. **Set typography**:
   - Configure font sizes for different hierarchy levels
   - Ensure minimum 24pt body text
   - Test readability from 4-6 feet distance

### Stage 3: Content Integration

1. **Create poster header**:
   - Title (concise, descriptive, 10-15 words)
   - Authors and affiliations
   - Institution logos (high-resolution)
   - Conference logo if required

2. **Populate content sections**:
   - Keep text minimal and scannable
   - Use bullet points, not paragraphs
   - Write in active voice
   - Integrate figures with clear captions

3. **Add visual elements**:
   - High-resolution figures (300 DPI minimum)
   - Consistent styling across all figures
   - Color-coded elements for emphasis
   - QR codes for supplementary materials

4. **Include references**:
   - Cite key papers only (5-10 references typical)
   - Use abbreviated citation style
   - Consider QR code to full bibliography

### Stage 4: Refinement and Testing

1. **Review and iterate**:
   - Check for typos and errors
   - Verify all figures are high resolution
   - Ensure consistent formatting
   - Confirm color scheme works well together

2. **Test readability**:
   - Print at 25% scale and read from 2-3 feet (simulates poster from 8-12 feet)
   - Check color on different monitors
   - Verify QR codes function correctly
   - Ask colleague to review

3. **Optimize for printing**:
   - Embed all fonts in PDF
   - Verify image resolution
   - Check PDF size requirements
   - Include bleed area if required

### Stage 5: Compilation and Delivery

1. **Compile final PDF**:
   ```bash
   pdflatex poster.tex
   # Or for better font support:
   lualatex poster.tex
   ```

2. **Verify output quality**:
   - Check all elements are visible and correctly positioned
   - Zoom to 100% and inspect figure quality
   - Verify colors match expectations
   - Confirm PDF opens correctly on different viewers

3. **Prepare for printing**:
   - Export as PDF/X-1a if required
   - Save backup copies
   - Get test print on regular paper first
   - Order professional printing 2-3 days before deadline

4. **Create supplementary materials**:
   - Save PNG/JPG version for social media
   - Create handout version (8.5×11" summary)
   - Prepare digital version for email sharing

## Scope Boundary

Keep this skill focused on the poster artifact: layout, source files, compile path, print checks, and final PDF. Treat upstream research text, data analysis, literature context, and figure generation as already-provided inputs unless the router selected another owner before this skill is used.

## Common Pitfalls to Avoid

**Design Mistakes**:
- ❌ Too much text (over 1000 words)
- ❌ Font sizes too small (under 24pt body text)
- ❌ Low-contrast color combinations
- ❌ Cluttered layout with no white space
- ❌ Inconsistent styling across sections
- ❌ Poor quality or pixelated images

**Content Mistakes**:
- ❌ No clear narrative or message
- ❌ Too many research questions or objectives
- ❌ Overuse of jargon without definitions
- ❌ Results without context or interpretation
- ❌ Missing author contact information

**Technical Mistakes**:
- ❌ Wrong poster dimensions for conference requirements
- ❌ RGB colors sent to CMYK printer (color shift)
- ❌ Fonts not embedded in PDF
- ❌ File size too large for submission portal
- ❌ QR codes too small or not tested

**Best Practices**:
- ✅ Follow conference size specifications exactly
- ✅ Test print at reduced scale before final printing
- ✅ Use high-contrast, accessible color schemes
- ✅ Keep text minimal and highly scannable
- ✅ Include clear contact information and QR codes
- ✅ Balance text and visuals (40-50% visual content)
- ✅ Proofread carefully (errors are magnified on posters!)

## Package Installation

Ensure required LaTeX packages are installed:

```bash
# For TeX Live (Linux/Mac)
tlmgr install beamerposter tikzposter baposter

# For MiKTeX (Windows)
# Packages typically auto-install on first use

# Additional recommended packages
tlmgr install qrcode graphics xcolor tcolorbox subcaption
```
