# LaTeX Poster Reference

Package selection, layout, design principles, standard sizes, templates, figures,
color, typography, and QR codes. See also `latex_poster_packages.md`,
`poster_layout_design.md`, and `poster_design_principles.md` for the deeper
per-topic guides.

### 2. Poster Layout and Structure

Create effective poster layouts following visual communication principles. For comprehensive layout guidance, refer to `references/poster_layout_design.md`.

**Common Poster Sections**:
- **Header/Title**: Title, authors, affiliations, logos
- **Introduction/Background**: Research context and motivation
- **Methods/Approach**: Methodology and experimental design
- **Results**: Key findings with figures and data visualizations
- **Conclusions**: Main takeaways and implications
- **References**: Key citations (typically abbreviated)
- **Acknowledgments**: Funding, collaborators, institutions

**Layout Strategies**:
- **Column-based layouts**: 2-column, 3-column, or 4-column grids
- **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_template.tex` - Customizable beamerposter template

**tikzposter Templates**:
- `tikzposter_template.tex` - Customizable tikzposter template

**baposter Templates**:
- `baposter_template.tex` - Customizable baposter template

### 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
