I played with demo too (waiting for my dongle) and I did not noticed this. I am using temp 5850, 2.2 gamma and 120L target values as I don't work in the total darkness. I mostly use ColorEyes. Profiles were wery similar.

Hi Martin, DotProof can satisfy needs like this - but working with *real* 1-bit RIPped data, exactly same as will be used for plates, is a must. (as saying, necessary but not sufficient condition). If using real data, results can be useful.

I1 pro is not even as precise as dtp-70. Well if it was *me* that had to do the calibration I'd go out and buy an Isis ;-) And, as we were using EFI before GMG and had to calibrate for every profile simulation (we proof everything from FOGRA39L through to FOGRA26L) the recal times have been cut by 95%. > Besides you don't need more than 4gb ram for gmg. Maybe if you have 3 44" printers and gmg dotproof option ($4,000) and only do dotproof proofs. I am running gmg dotproof in 32bit and I have 2 44" licenses and one 24". It flies. Bottleneck is speed of my proofers (880 series epsons). We're driving a 9880. What do you think of dotproof? I'd like to have it -- in the same way I like to have 64 bit :-) -- but the only time we are ever asked for dots is when we supply ads to US magazines. I'm not forking out that much cash just to satisfy their specifications as the majority of the proofs never make it to the US because the deadlines are too tight. Are the dots good/similar enough to catch problems like moiré in fabrics etc? We do a lot of skin and fabric work and I really miss the control we used to have when it was us who made the films :( -- Martin Orpen Idea Digital Imaging Ltd

I had time this evening to work on the profiles. I did get Profile Editor to work on Mac OS 10.6.7. Color Indicator Patches, under Gradations, are all black, but I have an old screen shot that shows the correct colors. I edited the canvas again and warmed that up by adding some yellow at the quarter tones, and held that off some at the 3/4 quarter tones, did the same thing with the matt paper used for proofing. The test prints all look really good now. Skin tones are much closer on all papers now, a really good match. I left the natural paper alone as it needed no edit, it also has the smallest gamut of the 3 medias. I think my friend will be happy when he returns and begins printing again. After all, good color is not always "correct color" its color someone will pay for, right? Are there other ways to achieve a match when the paper whites go from pretty much neutral to warm? In this case its the skin tones that really matter, and holding detail in the shadows. The 3 paper whites are as follows; Matt L96.2 a-0.6 b-0.2 Canvas L97.8 a-.06 b1.1 Natural Rag L96.4 a0 b4 Thank you everyone, David
