Cast n Cure

Vinfoil’s cast n cure™

What is Cast & Cure

In graphic arts industry Cast & Cure is used as a technology to transfer holographic patterns on top of printed images. Different from cold foil there’s no transfer layer being applied to the sheet. It is more or less a micro embossing of a holographic pattern.

As the holographic pattern is “embossed” into the coating surface pressure from following units will flatten this effect and make it disappear. This is why the technology is used very often in the last coating unit at the end of press. When applying the effect in a different section of the press
(e.g. printing unit) the pressure in the following units should be switched off.

“The holographic film can be used multiple times”

Application of UV Coating

The UV coating can be applied partly or in solids from a printing unit using an offset plate or from a coating unit using a stripped blanket or a flexo plate.

Transfer of holographic pattern & UV Coating

During the transfer of the pattern the holographic texture of the foil comes in contact with the wet UV coating on top of the printing sheet. During this contact the UV coating is being cured through the transparent holographic film. The result is a vice versa of the holographic film pattern on the printed sheet.

Release and rewinding of the foil

After the pattern has been transferred and the UV coating has been cured the plastic film is released from the sheet surface. The plastic film for Cast & Cure can be used multiple times, until the pattern on the plastic is fading away or the plastic film gets worn. The number of passes is depending on different parameters such as intensity of UV rays, type of coating, amount of coating etc.

A process with many advantages

A fast, flexible and cost-effective finishing technology:

  • Enables full-surface or partial sheet decoration at high speeds
  • High-speed holographic applications up to 15,000 sheets per hour
  • UV coating can be applied from printing unit or coating unit depending on press configuration
  • Foil reels can be re-used several times depending on UV energy, UV coating amount and foil type.
  • Job changeovers, with or without foil, can be performed in just minutes
  • Creates holographic patterns in combination with metallic effects if used in combination with metallic cold foil or metallized board to replace expensive holographic metal foils and reduce the cost per sheet.
  • Outstanding flatness of the output – optimal further processing
  • Speed-to-market potential – very short production times
  • Ideal for small print runs and frequent job changeovers
