Dear Stephan,
Grayscale profiles require special profiling software other than what
is used to profile colour devices.
There is a specialist package available from iccTools.com which allows
control of the following: (it is called iccGrayscale)
It allows the setting of the following preference defaults.
1. CMM (any that you have available on your system except Adobe)
2. Set any rendering intent.
3. Profile Quality (Normal, Draft or Best)
4. Media type (Gloss or Matte)
For Data Input you have the following choices:
1. Hardware (which includes Spectrocam, DTP41 and DTP22) you can set a
grayscale step measurement target using either 5, 11 or 21 steps.
2. Manually you can set a tone repro curve using the inbuilt curve
editor.
3. or in the Dot Gain dialog enter your own values (as %) from 0 to 100.
This also has 7 inbuilt standard value setting for various grayscale
uses.
4. Gamma setting control from 1.0 through to 3.0
5. and last but not least, the ability to build grayscale profiles
interpreted from you own existing CMYK profiles or other grayscale
profiles.
But there is more.
You can also set both the media white point and the media black point
independantly of each other using LAB values.
Oh, one more thing, it allows the setting of the Min Dot on a scale
between 0% and 10%.
It's a pretty cool app and if you are into ICC trivia, it creates a
wonderful grayscale profile icon.
You will have to contact email@hidden for further info.
