Danny,
This will work if you already have a printer profile. But what is the result
if you do not use a printer profile and print with "No Color Management"?
Does Photoshop convert to RGB or CMYK and pass that on to the driver? Does
Photoshop pass on Lab values and the printer driver converts to device
values (even with color management disabled)? I'm trying to understand what
the processing chain would be in that situation.
My intent is to print a process control strip which is independent of a
printer profile (such as R, G, B, and neutral ramps). I understand the
process if the image is RGB, but I'm trying to figure out what would happen
if my image was Lab instead.
