Avoid trimmed speech balloons, color registration blur, or white gaps on full-bleed panels by following this technical prepress checklist before submitting comic files to StationeryHQ.

1. Essential File Specifications

File Format: Single multi-page PDF (Page 1 = Front Cover, Page 2 = Inside Front Cover, ..., Last Page = Back Cover).
Finished Trim Size: $6.625'' \times 10.25''$ ( $168.275 \times 260.35\text{ mm}$ ).
File Canvas Size (With Bleed): $6.875'' \times 10.50''$ (Includes $0.125''$ bleed on all 4 sides).
Resolution: $300\text{ DPI}$ minimum for color art; $600\text{ to }1200\text{ DPI}$ recommended for pure black-and-white line art.
Color Mode: CMYK (SWOP or GRACoL profiles).

2. Inking, Lettering & Rich Black Formulas

Text and line art print best when set up specifically for digital presses:

Pure Black Linework & Dialogue Text: Set all speech balloon text, sound effects, and fine black ink outlines to 100% K (0C / 0M / 0Y / 100K) with Overprint enabled. This prevents fuzzy edges caused by CMYK color registration alignment.
Rich Black for Large Panel Shadows: For large, solid black backgrounds and shadow areas, use Rich Black to achieve deep, velvety density:

$\text{Rich Black Formula} = 60\%\text{ C} / 40\%\text{ M} / 40\%\text{ Y} / 100\%\text{ K}$
Total Ink Limit (TAC): Ensure combined CMYK ink density does not exceed $300\%$ to prevent ink smudging during high-speed folding.

3. Safe Margins & Two-Page Splash Spreads

Layout Element	Minimum Clearance	Pre-Press Guidance
Lettering & Speech Balloons	$0.25''$ ( $6.35\text{ mm}$ ) inside Trim	Keep text away from trim edges to avoid clipping during page cutting.
Panel Borders (Non-Bleed)	$0.25''$ ( $6.35\text{ mm}$ ) inside Trim	Maintain consistent outer margins for clean, framed layouts.
Gutter Clearance (Perfect Bound)	$0.50''$ ( $12.7\text{ mm}$ ) inside Spine	Keep vital art and dialogue out of the center binding fold.
