I know, but is this really any different from all the other difficulties customers presented you with before this? What happened when they converted to ISO Uncoated or an IFRA news profile and posterized some colors by using rel col instead of perceptual? Why not ask them to use the older ISO Ctd v2 and you take it the rest of the way—and ask for original RGB images when they have them? And get or make some decent device links with better highlight scaling?
It is different. As most people (in Europe) are used to using FOGRA39, the 51 experience is very different. What you see on screen is not what you’re going to get. And it doesn’t matter whether you use perceptual or relative in Photoshop, those light, white skin tones don’t have enough yellow in them.. Problems with uncoated or newsprint are usually issues with density range expectations and clients can appreciate that images will need a bit more intervention. This is easy to explain and fix in a pre-press workflow. But, again, FOGRA52 is a big problem (as I’ve mentioned here before). Again the issue is with yellow. The ECI profile cannot be replicated from the published data. You cannot create a viable ICC profile from this published data using either i1 Profiler or Argyll etc. You get CMYK separations with almost NO yellow! It’s not unreasonable to expect that newer standards will give you better results... -- Martin Orpen Idea Digital Imaging Ltd
