One characteristic of a good Ink will be how UV stable it is Ian. This is one of several reasons third party inks should be questioned when not from reputable sources. I am in no way any sort of expert on ink or printers but Life expectancy of inks must take into consideration how UV stable it actually is.
I would doubt the print media will give any added benefit to how UV stable an ink is. certainly, the ink may have more bite on the surface helping prolong its life on scratch/rub/abrasion life but not against UV damage.
what i mean is… Ink sits on the surface of the vinyl. UV light comes from above… hence why the vinyl below wont benefit the ink on top. However, this is were regular "clear" vinyl used as a laminate is outweighed by "proper" Laminates with UV filters specifically aimed at prolonging/protecting the ink on the vinyls surface. This i expect why we pay a bit more for a proper laminate as opposed to just a clear vinyl laminate. -
correct me if im wrong but when you heat the vinyl it opens up pours and allows ink into them, which may give more protection
this might be a load of rubbish, but might be something in it? -
Hi Ian,
I certainly have no experience or knowledge of solvent inks on vinyl, but what you described is how the older aqueous based inks work.
As far as I understand, all media to suit them (aqueous based inks) have an ink receptive layer on top which absorbs the ink and seals over the top. (I had always assumed that the ink just sat on top ) 😕
Still referring to aqueous based inks … I can imagine that the uv stability of different quality media could vary considerably … but I have come to the conclusion that some sort of overlaminate … especially a good quality uv rated one is the best insurance.
