Guys
One occasionally hears that a colour profiling SW makes a profile which has to presume something about the data it is expected to convert. Talk of digital camera SW being <based> on sRGB input reinforces this thought.
There appear to be occasional issues in Perceptually mapping colour [I've seen it strong blue and green] which is pretty much on the edge of a large - ish space like A-RGB to, say an Epson 7000 printer space. One sees blocked, detail - less areas of printed colour which look almost relatively mapped - could this be an issue of the data a profile is <expecting>?
Dan Margulis has suggested [I think, didn't read this part myself - yet] that a conversion to ColorMatch RGB [or at least sticking to ColorMatch as a source] can assist in rescuing the situation - but it would seem that this would clip the strongest colours and therefore cause it's own problems.
Are we banging up against the limits of the technology? What's the deal with mapping really strong colour to a print space from a larger workingspace - I'm sure the CMM should handle it but I'm seeing it fail. Could thsi be why ColorMatch has remained so popular in some fields?
Perhaps the imation CFM would be able to handle thsi but it seems to be discontinued <for the desktop>. I wonder if those nice guys at Imation might make it shareware now??
