Hot Foil Blocking vs Cold Foil Blocking

There’s much debate over whether the greatest benefits come from using hot foil or cold foil. Obviously we’re biased but hopefully this page can help make your mind up for you.

What is hot foiling?
Hot foiling is the technique which transfers foil of any required shape, colour or texture onto a required substrate. It uses a foiling die, made from brass, magnesium, copper or aluminium, and a combination of heat and dwell time to create the impression on a flat surface.

What is cold foiling?
Cold foiling is very similar but applied rather differently – no heat or foiling die is required. The design shape is applied to the substrate in adhesive and then the foil is pressed onto the paper. Then the foil is removed where none of the adhesive was originally laid leaving a foil design on the substrate. Then a UV light dries the product to completion.

So what are the advantages of hot foil blocking?

  • The quality of the final print will be better. Cold foiling users suffer from pinholing
  • Hot foiling is better for jobs not requiring a large foiling area but by no means is size a limiting factor
  • Cold foil requires an extremely clean environment, hot foil doesn’t
  • UV lamp issues can be a common issue when cold foiling
  • Hot foiling is easily combined with embossing to create stunning fluted effects
  • Hot foil can be applied to rough stock and textured papers, cold foil can not
  • Ideal for short and long print runs
  • You’ll get a higher end appearance using hot foil blocking
