Digital BW, The Print

This is the workflow I use (so far) to get results with the RIP using 
stock inks that are, in my opinion, very close to if not equal to 
that of a Pieziography print using quadtones -- and with negligible 
metamerism. The OS on my computer is WIN98SE so descriptions of input 
fields may not apply exactly to other OS's. There is some trickery 
going on here; that is, I'm tricking the RIP into printing at 
2880x1440 dpi on Epson Enhanced Matte paper using Matte Black 
Ultrachrome ink (the RIP doesn't want to let you do this). Okay, here 
goes...

From the START button select <settings>, <printers> and then right-
click on the icon for the RIP (lablelled "Epson StylusRIP 2200" on my 
computer). This should bring up the RIP Properties dialog box. 
Settings for this box:

General: default settings
Details: default settings
Color Management: Manual, defaulting to AdobeRGB1998
Paper: default settings (and common sense, set what you want)
Graphics: Resolution 2880x1440, all other fields default settings
Fonts: default settings
Device Options:
     paper: EPSON Proofing Paper Semimatte_2880x1440
     ink: color
     high speed: off
     CMYK simulation: SWOP
     RGB simulation: Adobe RGB
     Greyscale control: image
     Auto cut: off
     Borderless: off
Installable options: Photo BK + Light BK

All other settings for the properties dialog box left at default 
settings
Click <apply>, <ok>

Open Photoshop and your image then assign the profile "Grey Gamma 
2.2" to the image.
Open the RIP, select <edit>, <color manager> and use these settings:

CMYK boxes: default settings
RGB: Custom
     Icc Profile: browse (the "+" key) to enter the profile you use 
     to print EEM at 2880 dpi on the 2200
Media: EPSON Proofing Paper Semimatte_2880x1440 (room to experiment 
here if you want)
Icc Profile: CPS SP2200 PSM84 (this field defaults to the profile  
associated with the media selected in the previous step, there is 
room to experiment here, which I haven't done yet)

Calibration: -blank-

Paper Configuration: 95% (I had to adjust down the ink density to    
compensate for the fact I'm printing on paper (EEM) different than 
the media I selected above (proofing paper), this is part of the 
trickery.
     
click <ok>

In Photoshop select <file>, <print with preview>, <color management>
Your source space should indicate Gray Gamma 2.2
For the print space select:
     Profile: Adobe RGB (1998)
     Intent: Relative Colorimetric
     Use black point compensation: checked on
Click the <print> button and then select the RIP as your printer 
(mine's labelled "Epson SylusRIP 2200") and then select <properties> 
and use the following settings:

Paper: common sense, select what applies. If you need to specify a 
custom size of paper scroll over to one of the "custom" icons then 
select the <custom> button to allow you to input your desired 
dimensions.
Graphics: Resolution 2880x1440, all other boxes to default settings
Device Options should have defaulted to the following:
     Media: EPSON proofing paper semimatte_2880x1440
     Ink: color
     High speed: off
     CMYK simulation: SWOP
     RGB simultation: RGB
     Greyscale control: image
     Auto cut: off
     Borderless: off
PostScript: default settings
Watermark: default settings

Click <apply>, <ok> which should bring you to the Print dialog box
Click <print> and you're on your way

I don't know why Epson doesn't want us printing at 2880 dpi with 
Matte Black -- I just hope I'm not harming the print nozzles, so be 
careful and remember this is a non-standard workflow (but then what 
is?). Happy printing.
