destination black point rgb profile i1profiler2

[tommih70847716]

I have profiled a 7-col printer with i1pro as rgb-printer.

I have recently tested i1pro 2 and possibility to make M1 and M2 -profiles with filtered UV-area.

Basic problem is that icc profile converts 0/0/0 black to a little bit greenish.

In M0 profile , black conversion with relative bpc on will produce (srgb 0/0/0 >  6/5/0 to printer profile)

M2 makes the best conversion from 0/0/0 > 0/1/0, probably because optical brighteners makes it look too blue on spectrophotometer.

Still, since linearizing of printer is rather limited and near best black (0/0/0) in printer there is easyli a greenish cast on dark areas.

It would be important that profile would convert 0/0/0 to 0/0/0 since it is visually the strongest black.

Is there any way to modify black point in profile side ? Or any other way ?

IF OBA's why not try the i1P OBA compensation module?

Does the black look greenish under differing illuminants?  There's no way to 'edit' the black of an RGB Profile in i1P.

Gretag's Edit Module should have no problem either editing what they call the "workflow" black point of the profile, or you can do a very selective (or not so selective) color shift on the black. There are a couple other tools in Edit that might help as well. Plus you can edit in RGB, CMYK, Lab or LCH - whatever's easiest for you.
