RE: Carbon tissue and inkjet inks, Was: Gum and inkjet

[Marek Matusz <marekmatusz@hotmail.com>]

I think it is a good idea. The pigmented inks when bought in bulk from MIS are not that expensive. On top of that they are well engineered with respect to particle size, dispersion, etc. The eboni black is a wonderful warm black and I am going to try it with gum. The CYM inks are nicely balanced for tricolor. I would stay away from the dye based inks. They are not very lightfast.

More about lightfastness.

I have just pulled a test print from my window. This was a colour print made on Epson 2200 printer on epson paper with OEM inks. It was hanging on a south facing window in Texas, lots of sun exposure. I am disspaonted to say that after two years the yellow pigment has disappeared almost entirely and I vaugely remember reading somehere that the yellow is least lightfast (maybe on MIS page). Both cyan and magents seem to be very stable.

I have also tested lightfastness of some pigments that I use for tricolor gum. I will report shortly
