In the C80 if you select a glossy media in the printer driver the black ink
is not used, it's just CMY. While this will limit the density's you can get
on pictorico, it also makes for a very well behaved curve at the dense end
and works beautifully. Here is a curve I worked out for the C80 with glossy
media, 2.2 gamma, and color controls set on photo-realistic, in the Epson
driver. This curve is applied after you invert, just before printing:
0 5
5 17.25
10 28
20 42.6
30 55.5
40 65.86
50 73.53
60 80.28
70 84.34
90 91.89
95 93.45
100 95
It's easiest to input this as a transfer function, save it, then load it
into curves. Be sure to reset your transfer function after saving the curve
as I think it gets saved and applied when you print if your not careful.
