Thanks. Sorry I can only read the online help. Unless I am mistaken I can’t demo this thing and it’s not cheap. I see the options you mention below in the Online Help under Gamut Mapping Variants. I note also there is the option to “Define Handling the Gray Axis in the calculation of the Perceptual Rendering Intent.” Can someone explain to me what these options are. Is there any more available literature on what these options do?
(They will also have applicability to something I am tinkering with in the B&W domain.)
I forgot to mention viewing lighting is selectable in PM where in Match it is not.
Grey axis is an option that can be considered this: use neutral grey for an paper independent color corrected grey from 3/4 tones to highlights for most situations. As Gretag suggest use paper grey for pass thru colored grey such as newsprint when the media base is colored such as pink or blue stock etc. In some cases users have had success with using paper grey with art papers as the cotton rag is usually quite yellow , so they prefer to leave the grey come through without correcting for this yellowness in the grey scale. It’s an option that is there for these cases.
To do B&W profiles many options exist, yet they all require more than one button profiling. Personally I have not tried any of the following but you can either build them in PM as rgb or cmyk profiles then create a device link profile or use Profile Editor and save as Gray Profile, use custom generated low saturation charts, and or custom N color profiles say for 3 or 4 color tri or quad tone blacks IF you have a rip that can accept multi channel separations.
What I do for B&W profiles is run edits on top of the TC 9.18 charts reducing the composite colors until I have a near neutral rendering that is much less metameric under the desired viewing lights. Just another example of when a editor is useful for all the wrong reasons!
