I recently switched to a new batch original Epson 3800 inks and low and behold, there was quite a color shift. I printed on two different papers and they looked identical (using their own i1photo created profiles). So this was nice and consistent as expected in a fully color managed environment. I re-profiled the first paper and the color was back spot on. Now instead of re-profiling the about 7 papers I regularly use it would be nice if I could apply a diff between the old and new profile to the profiles of the other papers. Can this be done, if so, does a tool for this exist?
Cheers, Fons.
