I'm curious to know: are you softproofing (onscreen) your scans to
the original or to a printed reproduction? If printed then which
output device are you using?
I ask because I spent an inordinate amount of time when I first got
into this to remove these very tints you are trying to recreate. They
were generated by rendering greyscale images through canned profiles
to third party media using different rendering intents. If you are
using inkjet I would think your hopes to achieve monochrome 'tints'
lays in a duotone solution. I use a ColorSavvy Colormouse to
digitally sample colours/hues directly into Photoshop as a spot
colour and then tweak my 'duotone' colour according to my printed
sample.
Sounds like a nice project. Good luck.
On another note (which may even apply here):
Mon ami Neil,
I'm just getting into the whole neutral grey quest with ScanOpen 4.0
on our Lino Saphir Ultra and Scitex Eversmart Jazz. Tweaking IT8
generated profiles seems like a reasonable place to go with
transparency and/or print workflows, but we are increasingly scanning
watercolour and canvas works. Using our existing IT8 reflective
profiles generate consistent magenta which varies in intensity
depending upon which profile being used with whichever paper/canvas
(ink,oil, acrylic) scanned. I read Hutchinsons Consulting paper
(1997) on setting hard and fast WPoint/BPoints for the Eversmart, but
was wondering if you have a scan or PS workflow for generating or
achieving neutral grey. And I can't seem to find any documentation
which gives actual Lab values for middle gray. I get varying results
when I come at it from different directions. Not huge, mind you, but
enough of a variance not to base a profile edit upon. Lab50a0b0
renders a (HSB) brightness of 46, while a (HSB) brightness 50 renders
a L54a0b0. Any hints on target levels? URL's.
your loving servant,
