You might want to eliminate the Beinfang laminating products as they have been sold off and the laminate coming in under the DK Impressions label is pure crap.
I bought a roll, assuming it was still Beinfang and I laminated a canvas and it turned all of my nice blue sky green. The laminate had a distinct yellow cast to it. Sent it back and got another roll with the same problem.
Whatever it is going on, it is definitely an inferior product from what Beinfang used to make and sell.
Who in their right mind would think that it would be ok to sell a laminate with a color cast to it when it is specifically being used to cover art?
Went and bought a roll of Drytac and I was back in business.
