Coloring Page Maker: Does Source Line Width Change a Coloring Page Maker Result?
It can. Our controlled test used two synthetic drawings with identical shapes but different black stroke widths; the downloaded coloring pages differed. Compare the preview and downloads for your own source, since this test cannot predict every image or style.

What we compared
We made two original 640 × 480 pixel PNGs on white. Both contain the same black circle and centered rectangle. The first has 2-pixel strokes and the second has 12-pixel strokes. No other source feature was deliberately changed. These are synthetic drawings, not photographs.
In Chrome we opened each image in the current production snapshot, selected Clean Outline and A4, generated a page, and downloaded the PNG. Both downloads measured 3508 × 2480 pixels. Comparing corresponding RGB pixels found 213,698 different positions out of 8,699,840. A difference count does not tell us which result looks better or whether all outlines are usable.
Try a comparison with your own drawing
Keep the original file and use an editing tool to make a copy with a different line weight. Convert both copies with the same paper and style, then inspect the actual downloads. Look at the important subject edges and the blank areas before printing. The correct weight depends on your image, output size and intended use; two input widths do not establish a universal optimum.
Photographs contain edges made by changes in light and color rather than one uniform stroke. Our synthetic test cannot predict what will happen to a particular photo. Other Maker styles may behave differently, and we did not test a physical print.
