    Question Conversion from U.S WebCoated (SWOP) to IsoCoated V2

    I have a pdf with an U.S. Webcoated(Swop) output intent.
    This has a yellow square wich is 4% c, 0% m, 94% y, 0 black.
    When i convert this to the IsoCoated profile, i get different colorvalue's: 8% c, 0% m, 86% y, 0 black
    I did this conversion with GMG Colorserver.

    Is it correct this way? Because the yellow become's much greener this way.

    You're probably using perceptual rendering intent. Try relative colorimetric.

    I tested the L*a*b* values quickly in Photoshop using AbsCol rendering intent:

    Original colour values = L83 a-8 b76
    New colour values = L87 a-8 b75

    They are both as green as each other and almost as yellow as each other, the major difference being the L value... Despite/independently of Lab values, I don't think that cyan is good when you want yellow, a little magenta would be better (this being an artistic viewpoint and not a scientific one).

    Relative intent gives different numbers in the above test, with the green being the same with more variation in the yellow.

    Did you create your own MX4 in GMG?
