Been using the Advanced Profiling System included with my z3100 for some years now to make profiles of papers and canvas for my z3100, but mostly using the APS and embedded spectro on the z for making profiles for my ipf8300 these days. Been thinking of getting the x-rite i1photo pro 2. Can anyone with experience using both of these speak to the quality of the profiles? I've been fairly happy with the APS, but I don't have anything to compare it to other than manufacturer profiles. Thanks
