Hotfoiling

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.



Flat bed hotfoiling

Flat bed - Highest quality for hotfoiling on uncoated substrates

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

Rotary Hotfoiling

Rotary is perfect for hotfoiling on coated substrates

In rotary stamping the foil is applied to the web by a rotating cylinder. A main characteristics is that the transfer time for the glue activiation is an inverse function of press speed. Since the contact point between the stamping cylinder and the mandrel is theoretically a line, the contact time while the web is moving becomes very short with an increasing web speed. This extremely short dwell time explains why porous materials are difficult to process rotary.  Therefore rotary stamping is appropriate for closed surfaces, such as on coated papers and plastics. 

 

Typical business areas for hotfoiling on coated, closed substrates: Food, cosmetics, health care, security
