Build a Proper Sublimation Sandwich
Protect your equipment with this material.
Unless otherwise instructed, always use uncoated white butcher paper on the top and bottom of your sublimation sandwich (available from Uline or Sam’s Club). The paper, thrown away after each use, protects your heat platen, bottom pad, and substrate from ink and other debris. Poly-poplin fabric is recommended for metal and glass.
