A couple of notes, mostly for my own future reference:
Spent most of the last two days fine-tuning my inkjet print workflow.
Currently I'm happy with it for most of the prints I've tried, in fact, before I went to sleep I looked at several prints again and did a little victory dance. Here's how it stands:
The preparation of the file is a subject for another day, but suffice to say it is at 300 dpi.
1. Color Preferences
Working Space: Color RGB (1998)
Conversion Options: Engine: Adobe
Intent: Perceptual (though I'm still not sure what the difference between Perceptual and some of the other options are)
Use Black Point
Dot Gain is 15% (this is important for the Duotone rendering)
2. Print Space (in Preview Screen): Profile: Color RGB (same as working space)
3. Printer Setup Screen
Custom - Advanced:
Media Type: Colorlife Paper
Color Management: Color Controls : Mode: Automatic
(There are two other options that in the Mode Box that I haven't fooled with yet)
sRGB has been tried and limits the output.
No color Adjustment works, but only if you are using a printer driver in section 2, i.e. in Print Space. But not as well as what I have going now.
Edge Smoothing: Off
4: Duotone Settings:
This is where the most tweaking happened.
Ink 1: PANTONE Process Black CVP
Curve: 50 = 15, 80 = 40
Ink 2: PANTONE Cool Gray 9 C
Curve: 50 = 40, 100=90
Ink 3: PANTONE Cool Gray 3 C
Curve: 40 = 30, 100 = 90
Ink 4: PANTONE Cool Gray 1 CVC
Epson 1280 with standard Epson Inks
With these settings, there is no color cast in the blacks. The whites have a slightly cool look. And the midtones are good. If you were thinking in Zone System terms, where Zero is black and 10 is White, there is still a very slight magenta cast, but only in one zone, which I'd say was about zone 7. But you have to look hard to find it.
One other note: After two solid days of printing, no smudging or extra ink. And of course the paper really does need a good chance to air dry overnight.
It takes about 7 minutes to print a 5 x 7, and 15 minutes to print an 8 x 12, more or less.
I've probably left some setting out, but this is most of it.
