I know that the coating used to prime glass and the like for dye-sub heat pressing is polyester, which is a synthetic polymer. Gesso is also a polymer. I was wondering if any of you have tried using gesso to sublimate a photo onto canvas or anything else. I want something cheaper and more profitable to prime substrates other than the super expensive primer LaserRepro sells to coat tiles. From my understanding, the only reason you can't sub on natural fibers is that the heat won't open any pores in the fibers like it will with a soft polymer. Any suggestions?
