I've had only one issue, perhaps not tex-related. In one document I had
a series of 1-bit png graphics. Most were correctly grayscale files but
a few were color, for example:
i40.png: PNG image data, 656 x 665, 1-bit grayscale, non-interlaced
t06.png: PNG image data, 613 x 664, 1-bit colormap, non-interlaced
There should gave been no differences: all appeared black-and-white. But
on paper the background in the "color" images was a very fine "gray"
screen. The png files were created with pnmtopng; next time I'll be sure
that all of my original files are pbm instead of some being pgm. This
determines whether the png file is grayscale or color. (Or maybe some of
The artifact may be related to the software used at the printer; I can
find out what that is if necessary.
