It’s the method through which gold, silver or coloured metallic hot-foils are stamped on various surfaces, like paper, leather, plastic etc.
What we should keep in mind when we want to use the hot-foil stamping method on our printouts:
The hot-foil stamping is achieved with stamping dies (metallic tint plates on which the design to be stamped pops out), which are warmed up and then pressed on the printout along with the foil.

This method is fully overlaying, which means there should be no holes underneath. On our page make-up program we choose to use hot-foil stamping with a spot colour we have to name and then use overprint.
On the final PDF we’ll send out to be printed, the background should be able to be seen intact when we close the hot-foil channel. This way, there’ll be no register problems.

We should also keep in mind that due to the die-stamping technique there are many things on our original design that cannot be stamped. So we should not use complex details on the design we want to stamp. Of course, it all depends on the hot-foil-stamping machine, as well as the way the die is made. However, in any case, since we don’t exactly know what the quality of the final product could be, we should create large and clear designs.
