A brief analysis of the advantages and disadvantages of hot stamping technology
In order to attract consumers’ attention and stimulate consumers’ desire to buy, nowadays the packaging of products is becoming more and more bright and dazzling. When customers purchase products, their eyes stay on each product for no more than 1.8 seconds. There are no less than 30,000 products in a medium-sized supermarket. In order to grab customers’ attention, novel and unique packaging has become a must for merchants. An important trump card. When you are shopping or strolling in supermarkets or shopping malls, you will find that metallic effects and holographic effects are increasingly used in packaging products. Mr. Sam McElree, Product and Sales Manager of KURZ Transfer Products Division (Transfer Products) using hot stamping technology, pointed out: “The packaging of perfumes, chocolates, chewing gum, films, CDs, DVDs, cigarettes and snacks is the same as the exquisite labels of wine, champagne and liquor. , also requires a high level of design. As market competition intensifies, packaging plays an increasing role in promotion, in general, eye-catching packaging and brand recognition through the adoption of holographic foils.” At present, hot stamping has become an important metal effect surface decoration method. It is an effective way to enhance the visual effects of labels, cartons, trademarks and other products, and is widely used. Hot stamping methods mainly include hot stamping and cold stamping. Both have their own advantages and disadvantages. Therefore, in practical applications, the appropriate hot stamping method should be selected according to the specific situation, especially when weighing cost and quality. More attention should be paid to this. Thermal stamping technology Thermal stamping technology refers to the use of a special metal stamping plate to transfer the stamping foil to the surface of the printing material through heating and pressure. 1. Advantages and Disadvantages of Hot Stamping Technology The advantages of hot stamping technology mainly include the following points. (1) Good quality, high precision, clear and sharp edges of the hot stamping image. (2) The surface has high gloss and the hot stamping pattern is bright and smooth. (3) There is a wide range of hot stamping foils to choose from, such as hot stamping foils of different colors, hot stamping foils with different gloss effects, and hot stamping foils suitable for different substrates. (4) Another outstanding advantage of the hot stamping process is that it can perform stationary hot stamping. The computer numerical control engraving and plate making (CNC) method is used to make the stationary hot stamping plate, so that the images and texts formed by the hot stamping have obvious stationary levels, forming a relief effect on the surface of the printed matter and producing a strong visual impact. Stationary hot stamping can give packaging a unique touch. It is precisely because of the many advantages mentioned above that the hot stamping process has been favored by the majority of users and consumers and is widely used. However, the hot stamping process requires the use of special equipment, heating devices, and hot stamping plates. Therefore, obtaining high-quality hot stamping results also means paying higher costs. Mr. Chris Corbett, international sales manager of ITWFoilmark Company, pointed out that the rotary hot stamping roller is more expensive and accounts for a larger proportion of the cost of the hot stamping process. It is the main cost factor of the hot stamping process. At the same time, he also pointed out that in the past five or six years, the price of hot stamping rollers has been reduced to a great extent, and the drop has been as high as 50%. In addition to reducing the cost of stamping cylinders, thermal stamping system suppliers are also challenging the limits of stamping speed. In the past, due to the limitation of hot stamping speed, most of the hot stamping work was done offline, but now the situation is very different. A few years ago, the hot stamping speed of hot stamping machines could not reach 5,000 sheets/hour. However, currently, the speed of both platform hot stamping machines and drum hot stamping machines can reach 7,500 to 12,000 sheets/hour. Of course, the speed of hot stamping is also related to the type of machine used. The continuous improvement of production speed has greatly reduced the cost of thermal stamping. 2. Development trend of hot stamping technology One of the future development trends of hot stamping technology is online hot stamping. The improvement of the chemical properties of hot stamping foil provides a reliable guarantee for the substantial increase in hot stamping speed. Therefore, the current hot stamping process can be completed online, and the application of online hot stamping technology will become more and more common in the future. In addition, sheet-fed folding carton printing is moving towards web printing, which also creates conditions for the online hot stamping process. Another development trend in the hot stamping process is to hot stamp first and then print, that is, overprinting on the hot stamping foil after hot stamping. The first hot stamping and then printing process also benefits from the improvement and improvement of the chemical properties of hot stamping foil, so that UV ink can be used for printing on hot stamping foil. The process of ironing first and then printing can provide a more superior decorative effect and improve the visual appeal of the image. Overprinting opaque or transparent colored inks after hot stamping can achieve charming effects, provide packaging designers with endless design options, and provide designers with a broad space to fully demonstrate their creative talents.
