What's the best for using as a backer (release) board in a dry mount press? I have always sandwiched the mat board with print between 2 sheets of 4-ply mat board with release paper, but I am now in the process of changing with new board with fresh release paper and wonder if it would be best to use 2-ply instead of 4-ply for both front and back or 4-ply for the back and 2-ply for the front? Also museum, conservation, or illustration board or does it matter?
