Digital BW, The Print

Steve,

Tom Baker responded to a similar thread on the ImagePrint forum as follows:

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.

Apparently, an RGB image file can be printed with a gray paper profile, but
it won't look the same as a grayscale image file printed with the same gray
paper profile. I've never tried this, personally.

BTW, all the reports I've read on the new Epson 4000 and B&W printing seemed
to indicate that a RIP will be necessary for neutral, no metamerism
grayscale prints. As Paul Roark pointed out in one of his posts things could
get interesting if one of the RIP companies decides to use the 2nd black
position for some other dilution of black rather than its intended purpose.
