Hi

I’m investigating on ICM proofing, and I download some examples that use the Windows ICM proofing.

The problem is that when I compare this proofing with the Photoshop proofing I get different results.

For example windows ICM convert white to yellow values, and Photoshop convert it to light gray+blue values.

anyone knows why ? what is the good proofing? (I change the internal engine of Photoshop to Windows ICM (instead of ACE), with no differences)

Note: I’ve an image with an internal profile, and the monitor and printer profile.

There are a number of things that can change the way your previews look. Which program are you using to do your preview?

Hi

I discover why the image appears yellow.

The image appears yellow because I calibrate my monitor to a temperaature of 6500 (D65) and the printer profile is calibrated to 5000 (D50), like all printer profiles !!!!. (ICM try to proof an image with 5000ºK printer profile in a monitor with 6500ºK, then it converts the image to yellow)

When I calibrate the monitor to 5000 (too yellow in my opinion) all appears successfully.

To know why Adobe appears correctly … is something dark. See next discussion to learn about it:
