For hot foil stamping the glue layer must be activated well and pressure needs to transfer from the carrier to the surface. Depending on the substrate surface, the transfer is easier or more demanding. Consequently different applications demand different characteristics of the applicator. For some applications rotary is better, for others flat bed has a great advantage.
The stamping process on uncoated papers is more demanding than on coated. With rotary application - due to the short line contact between the tool, the foil and the substrate - often 35, 40 or sometimes 50 m/min cannot be exceeded. Pantec GS Systems flat bed systems can increase the contact time by factor 7 or higher. This allows higher linear speeds, better transfer quality and cheaper foils and cheaper tools.
Typical business areas for hotoiling on uncoated substrates: Wine, spirits, security, tax stamps.
RHINO™ is a fast flat bed hot foil embossing and hologram insetting system with up to 25´000 strokes per hour. With its revolvable head even multifoil designs can be manufactured at reasonable speed in just one single pass.
