I'm asking for advice/suggestions for a friend of mine and I hope you guys can help...here's the situation--in his own words:
"For the past several months I worked on a catalog of equipment that is largely machined aluminum and steel. We took new photos of much of the equipment, using existing images from the previous catalog for the rest. The old images entirely grayscale, with colored knobs added as overlays. The new images were taken with a Canon EOS 5D. Onscreen they look great; the printer's proofs (calibrated inkjet) look great. Much of the printed job is problematic. Many of the new images have a magenta or yellow cast. The client and I met with the printing company; they claim the color shifts we see are normal, within press tolerance. My client is not happy.
Now I know why the older images are gray scale! However, we like the richer look of the new images. What can I do to minimize the press issues? One thought I had was to use a much more aggressive GCR for the pages with this kind of image. I just rasterized one page of the PDF sent to printer. It shows they image to have very little K (1-10%), even when the CMY values are something like 45 48 52.
Is that a reasonable approach? If so, how should I procede? For this printing, I allowed Distillier to convert the RGB images to CMYK."
When I asked him about any sort of press profile, he reported the following--he's based in the US:
"The printer had no special profile. They asked for US Sheetfed Uncoated v2. The proof is OK. Perhaps 20% of the run is OK, but the rest varies. I think the issue is that with very neutral images, small variations in ink (esp M) become very visible."
Advice and/or suggestions I can pass on?
Thanks much!
