The
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).
A couple of things to add:
1) Since the "color-matching" processes of these RIPs use no ICC
profiles - what are users sending to clients in place of a press/target
profile?
2) In doing some testing here with Oris I found their deltaE numbers to
be rather "optimistic". I took the same measurement data into Measure
Tool and found that I had not improved at all over my current proofing
scenario (comparing measurements of TC3.5s and IT8-7/3 from press and
proofer). Anybody else done similar comparisons?
3) Your experience seems to depend a lot on which proofer you have. For
example - I've got the KPG 5542 (HP 5500 with KPGs firmware) and Oris
does NOT like to play with this unit. The API's weren't written for it
- so use differed quite a bit from the "wizard-based" approach laid out
in the "manual".
4) Lastly, Oris apparently has 1 tech support guy: Lewis. And while
Lewis really knows the software, if he's out on site, or at lunch, or
in the potty you're pretty well screwed. No one else has a clue. GMG's
installation and tech support are farmed out to a color-consultancy who
never bothered to call me back when I wanted to test the product out in
my shop.
Roger, how do you spell it? Say la vee.
