"If you can scan in CMYK thats even better."
"Hope I helped and didnt confuse" [Denis: You did confuse.]
"What I was saying is that scanning in CMYK gives you a better
representation ..."
Ed,
I have extracted what you said, twice. It must be confusing to anyone less
knowledgeable than you about scanners. That's why I belabor the point.
Barring some recent development (please provide details if I'm wrong),
scanners all scan in RGB. Is this not to be expected of a transmissive color
process?
Any scanner that offers CMYK output is merely converting the RGB information
to CMYK before you get the file.
