I have been wondering about an rather old idea of producing a printer that uses dye inks, but coated with a clear solution containing metal ions, that could bind the dyes and renders them insoluble, causing a precipitation reaction, thus forming an in situ pigment on the paper surface. This way there won't be any gloss differential, metamerism or bronzing. Metallo-organic compounds are far more fade resistent to pure organic dyes.

It is comparable to the UV-curing method of some inks, which use high energy UV light photons to cause a polymerization process instantly of the ink sprayed on the surface, that seals the dyes used in the ink and protects it against water, air and light.

"solution containing metal ions"
Any idea how to make this ?

Would it be spayed using a printer or airbrush?

"Addition of metal ions to improve lightfastness of inkjet inks"

FIELD OF THE INVENTION
This invention pertains to inkjet ink formulations having increased lightfastness, and, more particularly, to the addition of divalent metal ions to inks to improve lightfastness.
