Hello, Using Publisher, I have been testing PDF output (X-4) in a CYMK color space using 16 bit RGB images (sRGB profile) and not all of the photos render correctly. Some of my layouts are grids of 36 images, and over half will render with reversed colors (yellows are magenta). I cannot find any differences between the RGB files that convert correctly that those that don’t. If I convert those images to CYMK in PS, the colors of those images will render correctly. If I export as PDF/X-3 2003 they all render correctly. (This is RGB). What could be the difference within these 16bit sRGB Tiff files? They do originate from different cameras. That should not make a difference. If I convert to 8 bit, this seems to correct the problem. Conversely, for such dense image layouts, (36 and 49 per spread) perhaps I should convert to CYMK as an extra proofing fail safe? Thanks in advance for any advice. RT Simon
