[filmscanners] RE: CMYK rant (was Digital Darkroom ComputerBuilders?)

["Paul D. DeRocco" <pderocco@ix.netcom.com>]

I don't see that working in CMYK mode does anything that couldn't be done in
RGB mode. Increasing C just decreases R, and so on. If you play with the
black undercolor removal, that accomplishes nothing because the data gets
converted back to RGB for sending to the printer driver, when then
reconverts to CMYK using its own undercolor removal algorithm. Or is there
something that I'm missing?
