It's probably too early at this point, but I am wondering whether
anyone is
trying to figure out a way to profile the new Epson UltraChrome K3
printers
in black-only mode (Photo Black, Light Black and Light Light Black).
The B&W mode is not profilable, its a fixed setting mode. The only
adjustments are a choice of density settings, and a hue adjustment
control.
Speculation and not a beta tester but ..
That's on the outside but it could still use a kind of "unsaturated"
profile internally. The possibility to feed the B&W mode with RGB and
Greyscale suggests that it actually converts to RGB first like the
drivers always have done with CMYK data. A profile would take care of
perceptual rendering of the greys on top of the factory added
linearisation. It wouldn't surprise me if it did work like that. If it
would use the one channel Black Only monochrome printing of the old
drivers but with 3 tone separations I doubt they would have added RGB
input. Many digital cameras don't have greyscale format output, that's
the only other reason I can imagine. Anyone fed the B&W mode with a
normal RGB (not neutral) file ?
To get the same profiling done with custom profiles is another matter.
I guess it is time to add an extra B&W rendering to color profiles for
the next generation printers.
