Hello List,
If you create CMYK profiles with X-Rite i1Profiler, pay close attention. From 1.4.2, the meaning of the black start slider in Profile Settings has changed.
A black start of 10 now means that from L*10 and darker, black is used, as opposed to a start from 10%, which are of course highlights.
So from now on, this is the rule:
- Select a Black start of 100 to get Black into tonal CMY values from 0-100%
- Select a Black start of 70 to get Black into tonal CMY values from 30-100%
- Select a Black start of 50 to get Black into tonal CMY values from 50-100%
- Select a Black start of 30 to get Black into tonal CMY values from 70-100%
- Select a Black start of 10 to get Black into tonal CMY values from 90-100%
A mistake is easily made.
I shall restrain myself from any sarcastic comment.
Met vriendelijke groeten - Cordialement - Kind regards
