Digital BW, The Print

The reason I suggested the HP Z series is that the current feedback
I've heard from users who have compared it to the competing OEM
solutions (Canon Lucia and Epson K3) find it the best in B&W printing.
I was under the impression that all 4 blacks are used when printing on
heavy fine art matte media, which seems to be what Clayton tends to
use. It is true that 3 blacks are used on glossy media. Even if you
feel the extra black used on the art media isn't much use, users claim
that the results are good.

This is not the same solution as the R2400 or the other K3 printers.
With the K3 printers, when printing a neutral B&W image thru the RGB
driver, all 8 inks are used, including C, M, LC, LM, and Y. When
printing in ABW mode, C and M aren't used, but bits of LC, LM, and
even Y are used. In contrast, the Z series printers only use the
blacks. I bring this up since Clayton mentioned this as a concern of his.
