Pick the best version
Render two or three takes per page and keep the cleanest lines.
- 03

Up to 4K on the models that support it. Upscale or add bleed in your layout tool as usual.

Coloring books — FAQ
Q1How do I get clean black-and-white line art?
End each line with the same style words, for example: coloring page, bold black outlines, no shading, no gray, white background. GPT Image 2 follows these well.
Q2What size should KDP pages be?
Use 2:3 for 6×9 in or 3:4 for 8.5×11 in close crops, at 2K or 4K. Then place the images on your trim size with bleed in your layout tool.
Q3Can I sell the pages?
You own what you generate, subject to the license of the model that made it. Check the marketplace's own rules on AI content too.
Q4Can I keep a mascot the same on every page?
Yes. Upload a reference image of the character; it guides every page.
Q5How many pages per batch?
Free accounts: up to 5 pages with 50 credits. Packs go up to 100 per batch — enough for several books at once.
