Preparing mini coloring books
Keep line art readable at small trim sizes.
Mini books need simpler art, thicker lines, and a DPI check at the actual small trim—not at the original canvas size.
Steps
- Choose the final mini trim first.
- Reduce detail and enlarge small gaps.
- Print one page at 100% scale before export.
How to verify the result
Example: check whether 2550 × 3300 pixels is enough for an 8.5 × 11 inch page.
Check: This is a calculation aid, not marketplace certification or a print proof.
Frequently asked question
Does changing metadata increase real DPI?
No. Effective print DPI depends on actual pixel dimensions divided by print size.
