Thread: Single-Sided Release Paper vs Parchment

Parchment paper is not necessarily silicone coated, although Reynolds brand (which I use) is and apparently so is Costco's. It woks just fine, and is large enough for an 11x14 print, but curls vigorously when hot from the press---this makes getting the print under the flattening plate something of a challenge. Except for my relict box of Kentona paper, the texture of the release paper hasn't caused any problems with print marring. And it is a lot cheaper than the last roll of release paper that I bought.

If parchment is working with no issues I don't think there is any harm. But be aware if you change dry mount tissue then you should test it with the parchment release first. There are two primary adhesive types sold as dry mount tissue, solvent acrylic and thermoplastic (polyethylene). The former is more agressive and will cross link better with more materials where the latter creates a surface bond and stops there. Some manufacturers and dealer/distributors sell both, and under the same brand they should have different names. Under one of the most popular brands for example the thermoplastic is less expensive than the acrylic adhesive (as should be the case) but they give no explanation as to why it matters. Many reversable adhesives may actually be thermoplastic but sold as archival and reversable so they charge a premium price for the less expensive and less aggressive product. Bottom line is that while parchment may work in one instance you cannot count on it without running a test to make sure the adhesive does not bond to it.
