A question that has puzzled me for a while:

I've seen number of tutorials that advice adjusting images for print so that they are compensated according to printers dot range: if dot range is for example 5-95 (minimum and maximum printing dot in that specific process), an image should be compensated to produce dot all over the printed image. That is achieved by lowering contrast (in this case by moving images white and black point by 5 %). (Or this is as I have understood it...)

But what is the relationship between profiled (eg. Euroscale coated v2) RGB 2 CMYK conversion and dot range compensation?? Does a particular profile take care of compensation or should it be done anycase? AFAIK profiled conversion compensates dot gain, but black and white point clipping isn't only due to dot gain - other printing process factors affect clipping as well.

So: should I compensate images as described or not? If so, should compensation be done before or after CMYK conversion?

I'd preciate your views.
