I think I might have come up with a quicker way to identify the plastic based
papers - heat. I found this out by accident - there was a piece of Epson photo
paper stuck in my soldering stand, and the soldering iron touched it and
burned it. That got me wondering...
So I attacked a sheet of copier paper, and some samples of inkjet paper with
my Microjet mini heat gun (which usually gets used for shrinking heatshrink).
The copier paper and Staples photo paper burned, but the gloss layer didn't
deform a great deal.
The Epson Premium paper, on the other hand (which seems to be resin or plastic
based) burned, but the back and front bubbled quite severely before it started
burning. Around the burn area, there's a lot of bubbling, very similar to the
sort of bubbling you see on burning plastic.
It seems the "premium" photo papers are more likely to be plastic-based than
the standard photo papers, based on my tests:
HP Premium Photo Paper, C6040APlastic based
HP Photo Paper, C1847AWood based
HP Coated Paper, 51634ZWood based
Epson Premium, S041706Plastic based
Epson Durabrite, S041732Feels plastic based
Staples Inkjet Gloss Paper, 153458Wood based
FYI, the HP Coated paper has the HP logo printed in the corner on one side.
That's the uncoated side. The coated side should look brighter and smoother,
and appears to be a clay-based coating.
Anyone care to comment? Besides the obvious stupidity of burning paper, I
mean. As the saying goes, "don't try this at home"....
