major benefits to most other Rips as I see them are GMG's proprietary
profiling process is iterative, each measurement cycle lowering the
delta E between the target and actual Lab values until it is within a
user specified delta E value or it can no longer be lowered. If you look
at the IPA Proofing Round Up results, you'll see they took 1st
place(colorimetric)with an average delta E of .89 compared to DTR004
(Oris took second). I have done this myself and gotten a delta E of .64
and could probably go lower by using GMG's own paper. This is all
accomplished without the need for third party software (ProfileMaker, ect).
Cute trick except: are you sure the process lowers the delta E of the
overall profile, or only of the particular test values that are being
used, while errors in colors that lie between those test values remain
the same, or even get worse ? (ie. it's a benchmark fudge, rather than
being of real world benefit).
