I'm finding a best way to profile an Epson Stylus Pro 3800 with Gutenprint
( Uncorrected color mode). I printed a test patches with targen+printtarg
but some patches (dark colored patches - not gray or black patches) are
over-inked: ink is visible from the back of the paper and some patches have
a lot of dark dots if I view the paper with a backlight.
If I reduce the overall density I have a decent print without dark dots and
the ink which go underside..
I'll like to print some sort of more dark patches with some density proof
and estabish what is the good density.
Is there some targe-printtarg options which I didn't see??
Do I have to hand adjust a targen output with a spreadsheet??
