AI page art

Presets that have artwork can render it: one page, a selection of pages, or every page still waiting.

Each illustration is drawn from that page's art brief plus your book brief — which is what keeps a recurring character recognisably the same across the book.

Image tiers

The tier sets the resolution, and therefore the price.

Resolution is decided by your trim, not by the subject. A coloring book is the largest page this app prints, so a tier that is comfortably print-quality on a small picture book can land far below the 300 DPI printers want on a big coloring page. "A coloring book doesn't need high resolution" is exactly the wrong way round.

Tiers below the print floor are still offered, and are labelled as proofs. Seeing thirty compositions at a third of the price is genuinely useful — you just cannot sell that book, and both the page checks and the release board will say so.

What a batch costs

The price is per page, quoted before you start, based on the tier stored on your book. The quote, the charge and the model all resolve from the same place, so they cannot disagree.

Rendering runs as a background job with a progress overlay. Close the tab; it keeps going.

Cancelling

Stop works at any point.

• A job that no worker has picked up yet ends immediately, and nothing is charged.
• A running job stops after the current page. You pay only for the pages that rendered.

Coloring books: pure black and white

For a coloring book in black ink, rendered line art is flattened to pure black and white.

This is not a stylistic choice. A black-ink interior has a minimum printable fill percentage, and the soft anti-aliased edges every image model produces sit far below it — so they print as nothing, and the lines come out broken. Nobody discovers this until a physical proof arrives.

Flattening is applied only to coloring-book line art in black ink. It is never applied to a colour guide, whose entire job is to show colour.

Colour guides

A coloring book can put a coloured version of each design on the facing page.

A guide is generated as an edit of its own design — the line art sent back with "colour this in" — not as a fresh picture of the same scene. Asking for "the same scene in colour" returns a different picture every time, which is useless on a page whose only job is to be a reference for the one opposite.

Guides face their design across the gutter rather than printing on its back, for two reasons: you can see the reference while colouring, and marker bleed from the design does not ruin it.

What to watch for

• Nothing is ever deleted from your art storage. Replaced versions stay, and the art library puts any of them back — so an illustration you paid for is never gone.
• A page with no brief is skipped, and comes off the total rather than leaving the progress bar short.
• Style prompts steer, they do not guarantee. Negative instructions in particular ("no border") are advisory to an image model and are sometimes ignored. Check the first render before committing to a batch of forty.
• Render a single page first. One page at the tier you intend to use tells you more than any amount of prompt tuning.
