Paul,

What do you mean by "correct prep work needed to make this into a viable
inkjet pigment" ?

In a sense, inkjet printers are photographic water-color painters.

The cyan is very lightfast, but it is subject to UV and gas attack.

There is a very interesting Dan Smith pigment that is directly opposite
carbon yellow in the color wheel and can make a single-pigment offset to
the carbon. It's indanthrone blue. I've actually used it in an inkjet
printer and fade tested it. It's not quite up to cyan, but overall in
the same league as our M + C cooling methods. And, it will not cause
the inkset to drift into green as it fades. The fade path will be
straight back to carbon warm.

Some innovative ink company ought to persuade Dan Smith or IS to do the
correct prep work needed to make this into a viable inkjet pigment for
B&W. I've obviously decided not to take on that task myself.
