As a printer for others I do inkjet and I do gum dichromate, and pt pd and silver, I have many reasons for using any one of the products.
I have always wondered about the difference between dye based inkjets and pigment based inkjets.... When I mix my pigments for gum printing the mixture is extremely thick and takes hours to dry, but with inkjet pigment prints the dry time is almost instantaneous. This leads me to wonder how much real pigment is in the lay down and second how is it possible for the pigment to get through the nozzell head configuration which in itself pretty incredible set of engineering.
I question the amount or the thickness or even the quality of the pigment, as there is many types of pigments that can be used for gum printing or painting for that matter, and when going to the pigment store I find myself looking at these characteristics as closely as would a painter grounding their own mixtures.
So is it a matter of small yield pigments that are able to get through the nozzels , and the manufacturers claim that its pigments so therefore an archival pigment inkjet print , But I am curious What Type Of Pigment Mr Epson and Mr Canon Mr Piezography, this is a thing about these claims that I have never clearly heard explained in paper or on threads like this.
I am always perplexed when I go to shows and I see these labels under the prints(archival pigment inkjet) and since the Manufacuturers say so its true I begin to wonder .. Are these labels Fake News to create for the artist a very comforting thought but how true is it really.
When I sell print to others ,with my own work I clearly describe what they are getting, When I am asked by my clients how long will their inkjets last and how should they describe them my answer is as follows.
Ink on paper, and I have no idea how long they will last as this is a new product that enough time has not passed to predict properly.
