Digital BW, The Print

Because CS4 dropped the "No Color Management" option for grayscale printing, I was curious how the remaining options with the most likely settings compared to what I use in CS2.  So, using a 1400 with Eb14 inkset, I printed a series of 21-step test files and graphed their Lab L values. 

The file was un-tagged.  The PS Color Settings include gray working space Gray Gamma 2.2 and rgb working space Adobe RGB (1998).  The printer driver settings were my matte standard Color Controls with gamma 2.2.

I posted the results at

The bottom line is that what I found was a change in printing densities as the printer warmed up and almost no differences in how CS2 and CS4 print with the settings I was using.

The CS2 prints were with 
(1) a grayscale file and "No Color Management" set in the print preview and 
(2) an rgb file with "No Color Management" set.  

The CS4 prints were 
(3) grayscale file with "Photoshop Manages Colors," "Working Gray – Gray Gamma 2.2," and "Perceptual" BCP, 
(4) grayscale file with "Printer Manages Colors" and "Perceptual," and
(5) an rgb file with "No Color Management."

So, maybe this is an argument in favor of leaving printers turned on.
