QTR-Quadtone RIP

Hello Paulo,

The icc profiles you mention are not used as working spaces directly,
as you would do with Adobe RGB or GG1.8 etc. Instead you convert to
the gray-lab.icc, do your editing of the image, and when ready to
print, convert to either the gray-matt.icc or the gray-photo.icc for
printing on matt or gloss papers. At least that was my initial
understanding of the process.

I personaly use the gray-matt.icc and gray-photo.icc for softproofing
via the View/custom menu in Photoshop while editing photos, and find
it unnecessary to first convert to gray-lab. I also have found that,
if GG1.8 is the normal working space for B&W work, my prints come out
identically regardless of whether or not they are converted to
gray-matt.icc or gray-photo.icc before printing. I don't know if this
is supposed to be that way or not but it has worked that way with both
a CRT monitor and LCD [both properly profiled]. 

I do continue to use softproofing with the two because I don't always
trust my eyes, as the room I use for working has multiple windows and
the lighting varies with the time of day. [Not the best, I know, but
the best I can do for the moment.] I also make a quick check of
highlight,midtone and shadow values before completing editing for the
same reason.

If anyone has issue with anything I have said above, feel free to
correct me.

Regards
Duane
