The upper platen cover is much like the lower platen cover, but fitted for the upper platen. It protects the upper platen from residue, inks, and other adhesives. While it doesn’t replace the need for a non-stick cover sheet, many heat printers find it useful. Direct-to-garment and sublimation printers consider it an essential accessory to protect their heating element from steam and chemical buildup. Use this with your Hotronix, Fusion, STX or MAXX 16x20 heat press. Heat Press Not Included.
