    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

    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?

    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:

    Thanks to all
