Eye Catching

UEI recommends taking monthly measurements to ensure that once placed in the machine, the hot stamp cylinder continues to rotate to the original value it was meant to achieve. “The rounder the cylinder and the impression rollers are, the better the system will perform,” Hutchison says.

It is also very important to keep the press as clean as possible, as the foiling process creates dust, according to Raney. He also suggests making sure the heating system is functioning properly, because heat control is a very important component in the hot foil stamping process. While there is much to consider with hot foil stamping maintenance, Stanford recommends converters keep three rules in mind: “Keep your die clean, always check compatibility of new substrate/foil combinations, and use your die maker’s advice.” n
