Hi Nikolay, such a thing is certainly possible, and I have some well developed stochastic fixed pattern dither code that could be applied to the task, but I guess I'm a little puzzled by the work flow :- normally in color management you strive to keep the profiling and final used workflows as close as possible, so the question is why the profiling workflow is 8 bit, while the printing workflow is 8 bit dithered ? What is doing the dithering for the normal printing workflow ? Why can't the 16 bit test chart be printed via that workflow ? > http://www.freelists.org/post/argyllcms/targen-samples-filter-out-bug-v135,1 > I suppose the > clarification "Note that some classes of the full spread patches don't > support generating the > total number of patches while being filtered - instead the points are > generated then filtered" > would be appropriate in targen -F option description. I've added this. Graeme Gill.
