The hot stamping process operates based on the principle of heat transfer. With the help of heat and pressure, the aluminum layer in the electroplated aluminum is accurately transferred to the surface of the substrate, thus presenting a unique metallic texture effect. Since electroplated aluminum foil is the most important consumable in the hot stamping process, from a professional terminology perspective, hot stamping is also called electroplated aluminum hot stamping.
Electrochemical aluminum foil is usually composed of multiple layers of materials, the base material is usually PE, followed by separation coating, color coating, metal coating (aluminum plating) and glue coating.
In the printing industry, electrochemical aluminum foil is often hot-stamped on paper, which is called hot stamping. Hot stamping is a general term for a process. Hot stamping does not mean that the hot stamping is gold. There are many kinds of hot stamping paper materials, including gold, silver, laser gold, laser silver, black, red, green and so on.
Ordinary gold hot stamping and laser gold hot stamping have wide applicability and can be used for most products. Whether it is a gold card, a silver card, a laser card, or a glass card, these two hot stamping methods can add unique charm, and are widely used in actual production.
The holographic laser positioning electroplated aluminum used in positioning holographic hot stamping is a special process application at the design level. It has a specific anti-counterfeiting pattern, which can significantly improve the anti-counterfeiting performance of the product and at the same time make the product grade leap. This type of electroplated aluminum is mostly produced domestically, and compared with foreign imported products, the price is more affordable, but the hot stamping performance is slightly inferior. The hot stamping effect of holographic laser positioning electroplated aluminum is closely related to the hot stamping temperature, hot stamping pressure, and vehicle speed control, and even has high requirements for the hot stamping machine model.
In the field of cigarette label design and printing, "hot stamping first and then printing" is a novel idea. This process has extremely strict requirements on the quality of electroplated aluminum. It must not only ensure that the hot stamping position is accurate, the surface is smooth and bright, the pressure is balanced and evenly distributed, and bubbles and paste are eliminated, but also pay special attention to the edges of the hot stamping pattern. There must be no obvious indentation, and the electroplated aluminum must have good adhesion on the hot stamping surface, and there must be no obvious scratches or scratches. You must know that the hot stamping process is essentially a process in which the paper is subjected to heat and pressure. For white cards and glass cards, the protection of semi-finished products is particularly critical. In the production process, various adverse factors that cause paper deformation should be reduced as much as possible, which will greatly benefit the smooth progress of the subsequent hot stamping process and the improvement of product qualification rate.
