These can be produced from magnesium, copper or brass. The die is shaped to the image required to be foil printed.Blind embossing:
The paper/board is shaped into a defined, permanent relief. Sometimes the sheet is foiled first and then blind embossed to create a deep foil embossed effect.
Sometimes referred to as combination stamping is where the foil stamping & embossing are done in one pass through the use of a foil embossing die.
The paper/board is pressed to create a pattern within the paper/board using a special die & makeready.
This is used on the base of the foil printing machine. By making use of different make ready materials a better foil print can be achieved.
This is the thickness of the film carrier. Most hot stamping foil is 12 micron thick although can be up to 36 micron in thickness.
Allows the hot stamping foil to release from the film carrier upon application of heat & pressure. This layer affects whether or not a foil is suitable for fine detail or large area coverage.
Adhesive or Size Coat:
The final layer in the foil construction is the sizing which serves to bond the foil to the substrate being stamped
This is real gold that has been hammered into extremely thin sheets and is often used for gilding.
This is a measurement of the surface tension of the surface of the material. If it is to be foiled the dynes level is recommended to be above 40, however we have found that some of our foils can work below 30 dynes.
This is when the foil is not adhering completely to the stock and leaves small ‘Pick’ marks. This can normally be resolved by adjusting machine settings or a change of foil grade.
