In the increasingly fierce market competition, in order to increase the added value of products and carry out packaging anti-counterfeiting more effectively, more and more people will use hot stamping technology on product packaging.
Hot stamping, commonly known as "bronzing", refers to ironing words and patterns of colored foil and other materials on the substrate, or embossing various convex and concave book titles or patterns. The essence of hot stamping is transfer printing, which is the process of transferring the pattern on electrochemical aluminum to the substrate through the action of heat and pressure.
When the printing plate heats up to a certain degree with the attached electrothermal base plate, it is embossed between the electrochemical aluminum film and the paper, and the adhesive layer, metal aluminum layer and color layer attached to the polyester film are transferred to the paper by using the action of temperature and pressure.
Bronzing of wire drawing bronzing paper is widely used in various printing and packaging fields. Bronzing is also the only printing technology that can produce bright and non discolored metal effects on paper, plastic, paperboard and other printing surfaces. In terms of commodity packaging decoration, the bronzing process can make the products have special effects such as brightness, gorgeous, laser, laser, wire drawing, mirror, wood grain, metal and ink. The hot stamping pictures and texts after bronzing paper processing show strong metal luster, bright color and high luster. Moreover, the processed products of bronzing paper look high-end and high-grade, and are deeply loved by the public. So as to improve the rapid development and wide application of hot stamping technology.
Now the bronzing technology is mostly divided into hot stamping and cold stamping.
Hot stamping technology refers to the use of special metal hot stamping plate to transfer hot stamping foil to the surface of printing materials by heating and pressurizing; The cold hot stamping technology refers to the method of transferring the hot stamping foil to the substrate with UV primer.
Hot stamping has good quality, high precision, clear and sharp edge of hot stamping image, high surface gloss, bright and smooth hot stamping pattern. A wide range of hot stamping foils can be selected, including hot stamping foils of different colors, hot stamping foils with different gloss effects, and hot stamping foils suitable for different substrates.
Cold stamping is a kind of printing technology. Special glue (ink) is used to adhere other parts of cold stamping anodized aluminum except the base layer to the surface of the substrate, so as to achieve the effect of hot stamping. Moreover, the cold hot stamping technology does not need to use the heated metal printing plate, but uses the method of printing adhesive to transfer the metal foil. Moreover, the cold hot stamping technology has the advantages of low cost, energy saving and high production efficiency. It is a new technology that meets the needs of the processing market in the future.
Cold hot stamping plate making speed, short cycle, can also reduce the production cost of hot stamping plate, faster and more efficient.
