Hot stamping, commonly known as hot stamping printing, has a long history in my country. It refers to the words and patterns of materials such as colored foils hot stamped on the first or fourth cover and the back of the hardcover book cover, or the titles or patterns of various convex and concave books are imprinted by hot pressing. Now, many fast printing companies are also using different types of hot stamping technology, let's take a look.
1. Cold stamping: instead of using a heated metal printing plate, the metal foil is transferred by printing adhesive. The cold stamping process has low cost, energy saving and high production efficiency, and is a promising new process.
2. Concave and convex hot stamping (also known as three-dimensional hot stamping): Using modern engraving technology to make upper and lower matching female and male molds, the hot stamping and embossing process are completed at one time, which improves production efficiency. The mold made by electro-engraving can transition from curved surface to achieve the three-dimensional relief effect that is difficult to achieve with the mold made by the general etching method. The emergence of embossing hot stamping enables hot stamping and embossing embossing process to be completed at the same time, reducing the process and the waste caused by inaccurate overprinting.
3. Holographic logo: The amplitude and frequency of the grating are changed by computer technology, so that the effect is more vivid and clearer than the color of the calculated pattern. If this holographic mark is used as the original copy, a large number of holograms will be lost, so as to achieve the purpose of anti-counterfeiting. According to the characteristics of hologram hot stamping logo, it can be divided into continuous holographic logo hot stamping and independent holographic logo hot stamping. Continuous holographic logo hot stamping is a replacement product of ordinary laser holographic hot stamping. Independent holographic logo hot stamping is to make the holographic logo on anodized aluminum into independent trademark patterns, and there are registration marks next to each pattern.
The holographic logo can not only have very good anti-counterfeiting performance, but also can incorporate special numbers or characters into the holographic logo according to customer needs. The holographic logo is hot-stamped on the packaging carton, not only the holographic logo is hot-stamped on the surface of the substrate, but also has a very high overprinting accuracy, which is more and more widely used in high-end carton packaging.
