The hot stamping process uses the principle of heat transfer to transfer the aluminum layer in the anodized aluminum to the surface of the substrate to form a special metal effect. Because the main material used for hot stamping is anodized aluminum foil, hot stamping is also called anodized aluminum hot stamping.
1. Ordinary gold, laser gold hot stamping. It can be used for hot stamping on most products, including gold cards, silver cards, laser cards and glass cards, and its application is relatively common.
2. Positioning holographic foil stamping. Holographic laser positioning anodized aluminum is a special process application in design, with corresponding anti-counterfeiting patterns, which can greatly improve the anti-counterfeiting ability of the product, and at the same time improve the grade of the product. This kind of anodized aluminum is generally produced domestically. Compared with imported products, the price is cheaper, but the hot stamping performance is slightly worse. Holographic laser positioning anodized aluminum has a great relationship with the control of hot stamping temperature, hot stamping pressure and vehicle speed, and even hot stamping models.
3. The special application of anodized aluminum in technology. Ironing first and then printing is a new idea in the cigarette label design and printing industry. The application of this process has high requirements for anodized aluminum. In addition to achieving the requirements of accurate bronzing position, smooth and bright surface, balanced and uniform pressure, no blistering, and no paste, special attention must be paid to the edge of the bronzing pattern without obvious pressure. The hot stamping anodized aluminum should have good adhesion on the hot stamping surface, and there should be no obvious scratches and scratches.
Everyone knows that the hot stamping process is actually a process in which paper is heated and pressed. For white cards and glass cards, special attention should be paid to the protection of semi-finished products, and various unfavorable factors of paper deformation should be minimized during the production process, which is of great help to the smooth progress of the post-gilding process and the improvement of the product qualification rate.
