Bob,
Not to my knowledge: ICC is based on D50 worldwide. But ink industry
practices are hard for me to pin down. Bear in mind that ISO-3664 which is
the world standard for appraising prints us built on D50 not D65. So, it's
confusing, at best. I think the D65 mixing ink practice is worldwide but the
whoel repro world is D50-based. So much for communications and
interoperability.
