I think it is worse than that and a good printshop knows it and they alter the image to the press specs. Nowaday usually with a ICM profile on top of the ink limitations. The figures above for the press dotgain say that the image has to be compressed far more than 4 % on the blacks. Usually the highlight can be controlled with the profile. My point is that the printshop's prepress people have to do their job good and based on the press information they have. Modern printshops have spectrometres and densitometres all over the place. It isn't the job of the photographer or designer to apply the limitations before the prepress people start their work. Ernst - Turn off HTML mail features. Keep quoted material short.
