But one bit of news - I made up a color chart of sorts with mixtures of CMYW and sure
enough "Black" which is 100 CMYW does fluoresce as the best WHITE I have seen. White toner
alone glows Blue as I've said - but when fully mixed with the other colors then I do see a
not so bad white.
ArgyllCMS isn't setup to create RGBW type profiles. You would have to do your
own
separation from RGB -> RGBW to make a profile.
(In principle the CMYK path could be modified to work as RGBW, but there would
be a lot of changes needed. I'm not sure if simply inverting device values and
CIE
values would work, since white is treated as a special value in fully adapted
colorimetry.)
