permanence of aqueous vs solvent inkjet

[bteifeld]

This is a question based on a thought experiment.

Assume you are printing the same image on the same uncoated paper material.

One print is based on aqueous pigment inkjet ink, the other is based on solvent pigment inkjet ink.

Assume that for all inks, the pigments used are the same(solvent cyan pigment same as aqueous cyan pigment, etc.)

Both are top-coated with a solvent-based protective coating such as Clearjet Fine Art Gloss.

Both will be in an outdoor environment in a horizontal orientation- daylight will be continuously shining on them.

As the only difference is the solvent used in the inks (water vs hydrocarbon)- should there be any permanence difference?

should there be any permanence difference?

Considering some aspects; an aqueous carrier *might* be less effective than the solvent adhering or penetrating the pigment to the uncoated media. Could the media absorb and reflect at different rates over time? Pigment being the same should have the same endurance. The top-coat should be the most protective and maybe influential agent in the test unless there is another component (resins, etc?) such as one not known or considered in the compound.

A test on the roof probably would be telling before too long.

I believe that your question is fundamentally flawed. If I remember my chemistry, aqueous ink and solvent ink pigments cannot be the same because of the basic chemical difference between the solvents.
