An AI or photo page failed the check. What do the messages mean?
- "The picture has grey shading, not clean lines: draw it again": the studio already drew a shaded picture once more by itself; click "Draw again", or change the idea.
- "The picture is mostly solid black: draw it again" or "The picture has no drawing in it: draw it again": click "Draw again".
- "The lines do not close into spaces to color: draw it again, or close them in the editor": click "Draw again", or use Edit and the Line tool to close the gaps.
- "A line is X pt: KDP needs 0.75 pt or more": use Edit, then "Thicken lines".
- "A line reaches outside the safe area": use Edit and erase what reaches the edge, or draw the page again.
