How to Prep Your Comic for Print
A step-by-step guide to using comicprint to ensure your files are ready for physical production.
Why does this matter?
Commercial printers require your files to be set up in a very specific way. If your pages don't have enough "bleed" (extra artwork on the edges) or if text is too close to the edge, you risk white slivers on your pages or text getting chopped off. This tool automates checking for those issues.
1Getting Started
Open the editor and drag your comic pages directly onto the browser window. We support PNG and JPG files. You can upload them all at once or one by one.
The main editor view where you organize pages and check for issues.
Once uploaded, select your Target Preset from the right sidebar.
Standard Comic
Traditional US comic size. Trim size is usually 6.625" x 10.25".
Manga / Digest
Smaller format, typically around 5" x 7.5" or 5.5" x 8.5".
2Fixing Common Issues
After uploading, you might see yellow or red badges on your pages. Click on a page to see details in the right sidebar.
Aspect Ratio & Bleed
If your art doesn't perfectly match the shape of the print preset (including bleed), you'll see a warning.
The Solution:
In the validation panel, you'll see a button labeled "Accept Crop & Dismiss".
Clicking this tells usage you're okay with us slightly zooming/cropping your image to make it fill the page perfectly. We center-crop by default, ensuring no white edges appear in print.
Resolution (DPI)
Print requires high resolution (usually 300 DPI or higher). Since screens are lower resolution, an image that looks big on your monitor might be too small for print.
If you see a Low DPI warning, it means your source image pixel dimensions are too small for the selected physical size. The only fix is to upload a higher-resolution version of your page.
3Covers
Standard comics have 4 cover slots. You can manage these separately from your interior pages by clicking the Manage Covers button in the left sidebar.
- Front CoverThe exterior front of the book.
- Inside FrontThe interior side of the front cover.
- Inside BackThe interior side of the back cover.
- Back CoverThe exterior back of the book.
4Exporting PDF
When you're ready, click Export PDF.
You'll be asked if you want to include covers.
- Include Covers: Best for digital distribution (Gumroad, Itch.io) or proofing. Creating a single PDF with covers first, then interiors.
- Interiors Only: Best for professional printing. Most printers want your interior pages as one PDF and your covers as a separate file (often a spread).
Preview mode shows you exactly how your pages will look printed.
