InkCheck by Artifex Innovations
Ship coloring pages you're proud of.
InkCheck is an automated QA gate for AI-generated coloring pages. Upload your art and every page gets inspected for the flaws that turn into 1-star reviews. You get a scored report: what's wrong, where it is, and whether the page is print-ready.
InkCheck is in private testing now.
AI made coloring books easy to make. Not easy to make well.
Generators spit out pages fast. But raw AI art ships with broken lines, gray shading that prints muddy, warped shapes, and near-duplicate designs hiding across the book. Readers notice. The 1-star reviews on AI coloring books all say the same thing.
Until now, the only QA was your own eyeballs, one page at a time. InkCheck does it in seconds, for the whole book.
How it works
Upload your pages
Drop in art from any generator. InkCheck doesn't generate pages. It inspects them.
Every page gets inspected
A multi-pass visual check scores each page against a print-readiness rubric built from real KDP print requirements.
Get the report
Per-page scores, every flaw flagged with its location, and a clear verdict: print-ready or needs work. A book-level pass also catches duplicate designs across the whole book.
What InkCheck catches
Broken lines
Gaps, disconnected strokes, lines that stop mid-shape.
Muddy shading
Gray wash and gradients that print dirty on paper.
Warped shapes
Melted geometry, impossible objects, extra limbs.
Open shapes
Regions where color would leak out past the lines.
Fiddly detail
Cluttered patches too dense for crayons.
Tight margins
Art crowding the trim edge.
Duplicates
Near-identical designs repeated across your book.
Print specs
Trim, resolution, and file hygiene for KDP.
Built for indie sellers
InkCheck is for independent sellers publishing AI-assisted coloring books on KDP and Etsy. If a generator made your art, InkCheck makes sure it's worth printing.
