[QUOTE=TerryWyse;119507]Upgrade to MonacoPROFILER 4.8.x ASAP....there were some major changes made to the color engine in 4.7...the upgrade may be free but even if it's not, it would be worth it. The changes made in 4.7/4.8 are what had me switching from ProfileMaker 5 permanently.
4.8 was released like 4 yrs ago, what was the major changes that is superior to ProfileMaker?
[QUOTE=TerryWyse;120926]Hi Dan, Photoshop CS4 ships with all the relevant "G7" profiles (GRACoL Coated1 and SWOP Coated3/5). Previous versions can simply download them from the IDEAlliance website and install them. No more reason to use the ugly Photoshop Custom CMYK settings!
Just a FYI- the "G7" profiles that ship with the CS4 apps are not the same profiles that are available for download from IDEAlliance. The black start, TAC, and the amount of GCR differ.
Best regards,
Todd
Not only that, but the Magenta is about 3% lower in the 10% area, which makes me wonder about using the Adobe GRACoL profile at all. See attached Excel doc. Press on top is GRACoL2006_Coated1v2, and press at bottom is Adobe's GRACoL profile that came in CS4.

I think the discrepancy may be the result of rounding when obtaining the Lab values (for the 10% Magenta) rather than any true or significant difference between the two profiles. Comparing lab values rendered from an IT874 using both profiles, the delta values are negligible:
dE Report
Number of Samples: 1617
Delta-E Formula dE76
Overall - (1617 colors)
--------------------------------------------------
Average dE: 0.12
Max dE: 0.76
Min dE: 0.00
StdDev dE: 0.07
Best 90% - (1454 colors)
--------------------------------------------------
Average dE: 0.10
Max dE: 0.21
Min dE: 0.00
StdDev dE: 0.05
Worst 10% - (163 colors)
--------------------------------------------------
Average dE: 0.27
Max dE: 0.76
Min dE: 0.21
StdDev dE: 0.07
I recently saw in ReadMe 2009 IDEAlliance 12647-7e how to get 16-bit readings in PhotoShop, and did so for the problem area, using Bruce Lindbloom's LabDotGainCalculator2, just using 16-bit readings instead of 8-bit in Info palette. Plugged those numbers in Excel, with a little math, and what was dE of 1 and needing dot gain adjustment on plate of -3.08 to get from Adobe GRACoL to GRACol, now being more precise because using 16-bit, is seen as dE of .353 and needing to only change -1.05 dot gain on plate to get from Adobe GRACoL to GRACoL. And this was the biggest difference between the two when using 8-bit, so I can see why you say there is no worries.
