Printing grey in color space
I'm REALLY hoping someone can help me at least find a direction to go in. I'm creating images in Photoshop and printing to a Xerox solid ink printer. If I print in greyscale everything is fine, but if I have an image that has both color and B&W portions, the greys come out green (or brown depending on whether I print from CMYK or RGB). Is there any way to have a portion of an image in a color space and others in greyscale?
Any tips on what I might try as far as the printer? If I print CMYK the greys come out really green but all the other colors are good. If I print RGB the greys come out browner (which is a little better), but other colors get muddy.
Is there any way to get a printer to stop trying to "interpret" greys as a color when in a color mode?
Thank you very much for anyone who can help.
Re: Printing grey in color space
One solution would be to run the paper through the printer twice, once for
color and again for grayscale.
If that is not practical, my first suggestion would be to adjust your
printouts for as neutral a result as possible. This can be done either in
Photoshop, or in the printer driver itself, using the individual color
sliders that are provided in the printer settings. Sometimes it is better
to aim for an overall warm or cool appearance, rather than try to get a
perfect neutral across the entire range.
Here's a test strip and a procedure for doing this with a minimum of time
Photoshop also provides printer "transfer" curves for adjusting the output
of the individual CMY colors - this is a somewhat archaic interface,
originally intended for PostScript printers. They do provide more control
than the manufacturer's slider adjustments, so there you may find it useful
in your situation.
If you will be doing much of this sort of thing, you may find it worthwhile
to experiment with having a custom profile made for your printer. The
procedure involves printing out a test image and sending it in to be
measured, after which you receive a profile. Cathy's is a good, reasonably
priced service with a good reputation http://www.cathysprofiles.com/ . You
may want to combine the custom profile with a final manual adjustment to
get clean neutrals.
