What one export includes
The colored page, the numbered page, the palette legend, and the answer pages in the PDF.

One generation produces the set of files for one image, not a single PNG.
The three views
- A colored page: the photo rebuilt as palette cells.
- A numbered page: the same grid as outlines and numbers, which is the page the reader colors.
- A palette legend: one swatch per number.
Drag the slider. The numbered page is the same grid as the colored one, with the color removed.
The PDF
The KDP PDF is 300 DPI at the trim you chose, 6 × 9 in or 8.5 × 11 in. Numbered pages come first. Colored answer pages follow, so the back of the book is the solution. PNGs of each view are saved with the job as well.
The browser preview is for deciding columns, colors, and shape. It is not the print file, and the photo you drop there is not uploaded. The studio upload is deleted after 72 hours, or sooner from the library.
