Keith, I printed for a few years using Strathmore 500 (2-ply) with a layer
of dichromated, unpigmented gum as size. Trouble was that the glue holding
the plies of the paper together was acidic and yellowed the paper and I
switched to printing on BFK Rives with gelatin sizing hardened in
formaldehyde. One layer of the dichromated gum size was not sufficient with
the fuzzier BFK. I did experiment and found that two layers worked but I had
come to like the other way of sizing. Vegan students sometimes use the
dichromated gum method since they don't want to use gelatin.
