Name a theme (ocean animals, flowers, cats, a US state, a child's name) or upload your own shapes. TangleBook fills each shape with vector patterns and returns a print-on-demand paperback: interior PDF with trim, margins and page numbers, a wrap cover PDF with the spine sized from the page count, previews and coloured examples. Every page is rendered and flood-filled at 300 dpi to confirm closed outlines and no cell too small to colour.
Create original coloring books with consistent characters, print-ready single-sided interiors, cover briefs, and Amazon KDP metadata.
毛玻璃（Glassmorphism）桌面书签 UI 设计规范。包含 5 套主题色板、CSS 变量系统、分类下拉菜单、报告卡片、时间线、回收站等完整组件的样式标准与实现指南。
Upload your own photos (pets, family, trips, products). InkLine turns each into a coloring page with even, closed lines and returns a print-ready book for KDP and other print-on-demand: interior PDF at 300 dpi, a matching wrap cover with the spine sized to your page count, and one PNG per page. Pick kids or adult lines, simple to detailed, 8.5x11, 8x10, 8.5x8.5 or 6x9, blank backs, bleed. No image generator. Every page is measured; a spec sheet checks margins, fonts and dpi.
Upload photos of your pet and get clean black-and-white line art, laid out as a printable PDF coloring book. Three difficulty levels for ages 3 to adult.
Build adult coloring books to sell on Etsy and KDP. Two editions in one download: a ChatGPT setup that draws the pages itself with no API key, and a Claude skill for sharper print files. Both write the phrases, draw in ten line-art styles, clean pages to 300 dpi, and build the PDF, PNG pack, cover and Etsy listing. Unlimited books, one price.
