Foiled by Foil

Low running speed on a rotary hot stamp machine is typically a result of the inability of the rotary hot stamp die to be able to regain enough heat after each rotation," he said.

Managing the temperature and pressure are issues that relate to speed. According to McElree, "Too much heat tends to dull the metallic finish [of the foil]; too little will cause incomplete foil transfer. Too much pressure will cause a distorted or debossed image and too little pressure will also cause incomplete foil transfer.
