Hi I'm using the ICM for proofing my printer output. I've the printer and monitor profiles. When I try to make a proofing with ICM and compare it with PhotoShop proofing, i see high differences. For example, ICM transform the white colors with yellow values. But when I make the proofing with the PhotoShop, it convert the white to light gray+blue (it is more realistic, and more accurate to the printed image). Photoshop can use the Microsoft ICM and an "Adobe Color Engine", with the same (light gray+blue) results. anyone knows why ? Note: I try all options in Photoshop (and using the windows ICM engine) to get yellow values without result. Note2: I use some other programs that use the ICM 2.0, with the same (yellow) results (I try with PaintShop Pro, the IcmView.exe, an example of the Black Book). ATt Ramon Graus
