Digital BW, The Print

Hi,

I have a 2200 which is becoming aged.  I use Photoshop, Qimage and the 
QTR rip.

I am thinking of moving to the 2400 (or maybe the 3800) and am 
attracted to the ABW functionality and K3 inks.

Qimage converts grayscale to RGB during the print process (so I never 
bother converting to grayscale after fiddling in Photoshop.)

Can anyone tell me whether I will lose something in the ABW process 
because of Qimage's habit of converting everything to RGB?

Thanks very much,

Fred Rothenberg
