Digital BW, The Print

You can print an RGB file with a grayscale paper profile in Imageprint.  It simply prints a grayscale image.  In fact, IP's color to b&w conversion isn't too bad.  It doesn't look 'strange'.
 
So far, I've been unable to get a print from an RGB file to print on a color paper profile that looks like the grayscale profile.  I've converted a grayscale to RGB and printed using a color paper profile, and it always looks a bit strange.

Steve,

To be honest, I've never tried to print a basically B&W image with selected portions in color, therefore, I really don't know what IP would do if a gray paper profile was selected.

In a nutshell, the setup in IP for printing B&W or color is as follows:

* If grayscale image file, then the appropriate "gray" paper profile is selected which, in turn, activates the Tint Picker. As of v5.6 selecting a gray profile also sets the inkset to "Gray Pigment Matte" (assuming you're printing on matte papers.)

* If RGB image file, then the appropriate color paper profile is selected which, in turn, sets the inkset to the correct color values...can't remember exactly what they are at the moment.

Therefore, I would think that if a gray paper profile is used with its corresponding inkset selection for B&W printing that any color might look odd. This would be an interesting experiement...Would IP print the color when it "sees" it? I know it would if a color paper profile is selected--and I suspect the gray portions would print as gray--but, then you would have metamerism, etc.

If you're curious about all of this, download the demo from Calumet Photo's website and take 'er for a spin. IP will print "DEMO" all over the image in large letters, which is kind of a pain, but an evaluation of the print is still possible.

Good luck,
Alan Huntley
