    Here's some doc about adding gamma options.
    It's not very hard. But if it doesn't work right the first time, testing
    different settings can cost a lot of ink.

    UFF
    In this document the gamma is to 0.3, but if i remember correctly i used
    gamma of 0.7 or somewhere close (I have an Epson 670).
    If you use printtool to set up your printing, you can set extra gs
    options. All you need to do with that is point to the file which contains
    lines like:

    %!
    %transfer functions for cyan magenta yellow black
    {0.7 exp} {0.7 exp} {0.6 exp} {0.5 exp} setcolortransfer

    I have that file named gamma.ps and keep it in my /home directory.
    I didn't test these settings out yet, but they should be a good starting
    point.
    I hope that's enough to get you going.
