Guys
A question about ColorVison's "Profiler RGB " if I may. I can't
just understand how it works from the scanner - it comes as a
printer testfile - on disk - with no printed target and is said
to be able to use an unprofiled scanner to read the patches once
printed.
I am sure it works fine because I have a lot of respect for
ColorVision but to me it seems like this:
The printed result likely contains distortion of the image
appearance, in relation to the original file data, so the
Profiler RGB SW plainly needs to make an output profile which
provides for correction of this deviation. That bit's obvious,
and easy.
I just can't get my head around how the printed target gets
scanned.
If the unprofiled scanner distorts the printed image's appearance
[ie it adds to or subtracts from the printer errors ] - then
obviously that distortion should not become part of the printer
[output] profile correction. So how can the Profiler RGB SW
"know" whether it's looking at scanner distortion or printer
distortion, or a combination?
I understood how Praxisoft [WYSYWYG?] did it with their pre -
printed target which profiled the scanner first - but this seems
very difficult to understand.
thanks
