Digital BW, The Print

David,

Below is the workflow I found through a search on the forum several weeks ago.  I believe Lou Dina wrote this.  Hope it is helpful.  I follow it and have very good results.

"Here is a step by step for Windows XP Users.

First, download Roy's Lab profiles and unzip them to your desktop.
Here is the link:

http://homepage.mac.com/royharrington/FileSharing2.html

After unzipping them, copy the files to the following directory:

C:\WINDOWS\system32\spool\drivers\color

Start photoshop and open a file, whether it be RGB or grayscale. If
you like the tonality as it exists on your calibrated monitor, then
you will want to convert the file to the Lab Grayscale profile, as
follows:

Image > Mode > Convert to Profile > Gray-Lab.icc
Be sure rendering intent is perceptual and black point compensation
is checked. Now, you file has been converted to the generic gray lab
space. If you wish, edit the file in photoshop until you get it the
way you want it. When happy, save it with the embedded profile as a
TIF, PSD or JPG file. Now you have a "master" file which you can use
to create a file for printing.

If you want to output to matte paper, do another conversion the same
as above, but use the "Gray-Matte" profile, with perceptual and BPC
checked. Save this and import it into QTR or IJC/OPM for printing.

If you wanted to send the file to glossy or semi gloss type paper,
use your master file and convert to the "Gray-Photo" profile, using
perceptual and BPC. Save and import into QTR or IJC/OPM for printing.

When printing from QTR or IJC/OPM, you will need to select the
appropriate profile for matte or glossy paper, and your other
settings as you usually do. When the print comes off the printer, it
should be a pretty close match from a tonality standpoint to what you
saw on your calibrated monitor.

Apparently, the Mac allows you to convert on the fly. With Windows
you have to save the converted file first as documented above. Hope
that clarifies it.

Lou

  What is the actual workflow? Should I convert the RGB file (which
  looks fine on screen) then save as RGB with the profile for print in
  QTR? Or should it be converted to Grayscale? (in which case converting
  first to Roy's profile wouldn't make a difference).

  David.
