Re: 16 bit and printer output -???

2005-01-13 by Tyler Boley

I'm getting out of my element here, but my understanding is that all
printer drivers make 16 bit ramps internally. Also, many profiles,
even color, use 16 bit LUTs. Of course IJC/OPM probably does not use
icc profiles in the strictest sense, but if their "profiles" use LUTs,
that's probably where that statement applies.
So some of this would not be extremely informative, until you see this-
"(16-bit files remain 16-bit)".
That answers the question.
