Digital BW, The Print

There was a lot of discussion about grayscale profiles a while ago.
I've worked out a bunch of the details and have adapted the linearizing
code to create ICC files.

It is now part of the QTR package version 2.3 which has been just uploaded,
available for both Mac and PC.

QTR-Create-ICC  is the newest feature.  It creates grayscale ICC printing
profiles.  Although packaged as a QTR tool it is a general purpose program that
can accurately profile any B&W printing workflow.  The current version only 
supports the Eye-One/MeasureTool data format.  It uses the same target files
and reference files that the QTR linearizing function has always used. The profiles 
created do full Perceptual Intent mapping of the grayscale and allow Ink Black and 
Paper White simulation in SoftProofing.  See Eye-One folder in either Mac or PC
versions for information.

See the main download page and follow the link at the top to
the beta versions -- that's QTR version 2.3
