Digital BW, The Print

When I've profiled Claria black only in a printer with the full set of color inks, I've added some LM to offset the slight drop in Lab A that usually is characteristic of Claria K's tones.

A similar altering of the Lab A distribution can be accomplished by simply adding a little Claria M from a small Claria cart.  

The graph at http://www.paulroark.com/BW-Info/Graph-4pc-M.jpg shows the Lab A and B distributions for the 100% K Black Only (BO), as well as the tonal distribution for Noritsu K with 4% Claria M added to the mix.

Looking at the actual test strips, I can see the difference between the BO and toned versions, but I'm not sure it makes enough difference to bother with.  Toning like this is an option, however.  I don't think dyes will separate or settle at all.

Note that I'm looking at this for gloss paper.  Matte papers may need toning, to the extent of about 10% M to counteract Claria K's tones.  I do not intend to go there.  

The Noritsu K inkset I'm working on is aimed at glossy photos and brochures, as well as general, all purpose printing if the dilution works.
