First, the definition of hot stamping process:
Hot stamping process: The process of transferring metal foil to the surface of printed matter or other items by hot pressing to increase the decorative effect.
Cold stamping process: It is a process of transferring metal foil to the surface of printed matter or other items and decorative effect without heating, only through pressure and bonding and peeling forces.
Second, the purpose of hot stamping:
The printed surface has a metal texture pattern of multiple colors at the same time, and it can also combine different pressing effects. In addition to the surface decoration function, hot stamping has an important role in anti-counterfeiting.
Three, advantages and disadvantages of hot stamping process:
1. Advantages:
(1) The whole face of hot printing products, no ink residue;
(2) No ink and other bad smell, air pollution;
(3) The color pattern is printed once to reduce the loss;
(4) The process is simple, the production management and process are smooth, and the product quality insurance factor is large;
(5) A wide range of processing, suitable for paper, wood, plastic, leather and so on.
2. Disadvantages:
(1) not suitable for stamping surface uneven pockmarked or matte substrate;
(2) Metal, glass, ceramics, nylon and other products are generally not suitable for hot stamping, unless first painted or screened;
(3) Match the pattern color with the base color of the workpiece: when stamping, the hiding power of the color of electrochemical aluminum (gold, silver, copper, red, blue) is very strong, even if the base color of the workpiece is black, it can be completely covered; However, when the transfer paper with lighter colors such as white and yellow is used on the black background for hot printing, its hiding effect is not as good as pad printing and screen printing.
Four, hot stamping process classification:
1, hot stamping process is divided into cold stamping and hot stamping
2, hot and divided: ordinary flat hot stamping, three-dimensional hot stamping (commonly known as relief and embossed hot stamping), holographic positioning hot stamping.
