Michael's review of the Hanemuhle paper with magenta cast raises an interesting question about inkjet vs dye-sub and photo processes. In the latter, we have CYMK or subtractive. Inkjet is also subtractive, but in a different way; instead of the eye being given a 'resulting spectrum' at every point due to the CYMK ribbon absorption, the dots 'fool' the eye into thinking that a VERY small region has a resulting spectrum. The eye integrates and 'sees' a color from the dots.
In the Han FB paper, starting with a magenta cast we assume to 'get white" a bit of cyan and yellow would be added in that area, giving a 'SUPERLIGHT grey" rather than white (
OR the eye As we saw in the checkerboard test" will perceive white when the neighboring colors have a magenta 'uncast'
in no case do I think the profile will result in our seeing magenta in a 'clear' area.
I for one was disappointed that Michael did not continue to tell us which it was. I don't buy the 'european look" nonesense either, but I doubt that this paper will give up on white. If the brighteners REALLY brighten, more than the darkening from the YC needed to produce white perception, then Hanemuhle might have something
Or NOT! :-)
