Process: Pure Black-and-White Line Art, No Grayscale

AI image generators are notorious for slipping gray shading, gradients, and off-white backgrounds into pages that were prompted as line art — and gray tones print muddy. The Process tab removes the grayscale from every made page and normalizes it to pure black-and-white line art in one click, preserving line integrity instead of destroying thin lines the way a blunt threshold filter does. Press Run All and watch the grid fill in — no AI credits are used here; it runs entirely on your machine, no external cleanup tools or per-page editing required.

Process also runs built-in anti-leak segmentation: it detects unclosed shapes and seals gaps in region boundaries — broken lines are what let color spill outside the lines in later stages. It doesn’t succeed on every image — if a page comes out with unclear, leaky color regions, the best fix is to go back to Make and regenerate that page rather than fight the segmentation.

Controls

• Run All — processes every made page. Re-running over existing results asks “Overwrite existing images?” first (no backups needed here — this step is free to redo).
• Click any single card to (re)process just that page.
• A card with a yellow warning means its source page hasn’t been made yet — go back to Make and fill it first.
