<P>Here's some doc about adding gamma options.

|

It's not very hard. But if it doesn't work right the first time, testing
|
|
<BR>
|
|
different settings can cost a lot of ink.

In this document the gamma is to 0.3, but if i remember correctly i used
|
|
<BR>
|
|
gamma of 0.7 or somewhere close (I have an Epson 670).
|
|
<BR>
|
|
If you use printtool to set up your printing, you can set extra gs
|
|
<BR>
|
|
options. All you need to do with that is point to the file which contains
|
|
<BR>
|
|
lines like:
|
|
<BR>
|
|
<P>%!
|
|
<BR>
|
|
%transfer functions for cyan magenta yellow black
|
|
<BR>
|
|
{0.7 exp} {0.7 exp} {0.6 exp} {0.5 exp} setcolortransfer
|
|
<BR>
|
|
<P>I have that file named gamma.ps and keep it in my /home directory.
|
|
<BR>
|
|
I didn't test these settings out yet, but they should be a good starting
|
|
<BR>
|
|
point.
|
|
<BR>
|
|
I hope that's enough to get you going.
