Hot foiling by Pantec

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.

A valid hotfoil alternative?

Coldfoiling

 

The improvements in cold foil technology resulted in more and more competition for hot foil. Due to the higher tooling costs in hot foiling compared to a flexo cliché for cold foiling, many brand owners and printers relinquished the higher brilliance and better fine line quality of hot foil for the benefit of economy. But there is a major factor of economy that is often not considered: Hot foiling with a powerful foil saving system quickly overcomes the breakeven point between the costs of cold foiling and hot foiling. Despite the higher tooling costs in hot foiling, hot foiling may become much more competitive than cold foiling. Because the foil saving not only covers the tooling costs, it generates profit. Moreover, the higher brilliance, the sharper edges, etc. make a positive differentiation in quality.

IS COLDFOILING THE BEST OPTION?

Cold foil on a first glance is more economic than hot foil because of lower tooling costs. But how is the calculation if the saving potential of hot foil is taken into consideration?
