Help System > ICC profiles
Here are the ICC profiles for our papers. If you download them and install them on your computer, you can "soft proof" what your images will look like when you get them from us.
They're either profiles we've done with our hardware calibrators, or they're manufacturers' supplied profiles specifically intended for our particular printer with that particular paper which we have found to produce excellent color-matching results.
Some of the files are .ICM and some are .ICC: the file extension doesn't matter; they're just different extensions of the same type of file.
