Hot foil stamping is the process of applying Hot stamping foil OR holographic foil by using a hot foil stamping machine.
The foil could be stamped on the substrates such as light papers, carton board, laminated board, plastics and corrugated board. …
The process is used on a wide range of products to create decorative finishes and anti-counterfeiting measures. In the packaging industry the applications include food, pharma, tobacco, and luxury goods packaging, as well as labels for products such as wine and spirits. Beyond packaging, hot foil stamping is extensively used on banknotes, greetings cards, and throughout commercial print.
There are 3 different operating way for the foil stamping process , flat-flat, round-flat, and round-round stamping
1,Flat-flat foil stamping machines operate on similar principles to those of flat bed die-cutters, with some presses being able to swap between both functions and others being fully dedicated foil stamping presses. In flat-flat foiling, the foiling dies are either attached to a flat honeycomb chase allowing for variable positioning, or in fixed positions on a flat metal plate, for repeat jobs. Whichever type of die carrier is used, the sheet and foil will be brought into position between it and the lower counter plate. This is either completely flat, for flat foiling, or mounted with counterparts to the dies, for embossed foiling. The press then brings the upper and lower elements together, delivering uniform pressure across the entire sheet
2,In round-flat hot foil stamping, the flat counterplate is replaced by a rotating cylinder. The die chase moves horizontally in synchronization with this to deliver a narrow linear zone of pressure where the die, foil, substrate, and cylinder meet
3, The round-round principle of hot-foil stamping is based on a rotary principle similar to that used by printing presses. Here, the dies are mounted on a cylinder that rotates in synchronization with a counter cylinder. The substrate and foil are brought together between the two in the narrow nip point
