In order to attract consumers’ attention and stimulate their desire to buy, nowadays product packaging is becoming more and more bright and dazzling. When customers are purchasing goods, their eyes will stay on each product for no more than 1.8 seconds. There are no less than 30,000 kinds of products in a medium-sized supermarket. In order to grab customers’ attention, novel and unique packaging has become an important factor for merchants. trump card. When you shop or stroll in supermarkets or shopping malls, you will find that metallic effects and holographic effects are increasingly used in packaging products.
Hot stamping technology application
Sam McElree, Product and Sales Manager of KURZ Transfer Products Division (TransferProducts) Mr. Wang pointed out: “The packaging of perfumes, chocolates, chewing gum, films, CDs, DVDs, cigarettes and food, like the exquisite labels of wine, champagne and liquor, also requires high-level design. As market competition intensifies, the role of packaging The promotional role is growing. In general, eye-catching packaging and brand recognition through the use 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 has considerable applications. widely. 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 The hot stamping foil is transferred to the surface of the printing material by applying heat 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 three-dimensional hot stamping. The three-dimensional hot stamping plate is made using computer numerical control engraving (CNC), so that the images and texts processed by the hot stamping have obvious three-dimensional layers, forming a relief effect on the surface of the printed matter and producing a strong visual impact. Three-dimensional hot stamping can give packaging a unique touch.
It is precisely because of the many advantages mentioned above that the hot stamping process is favored by the majority of users and consumers and is widely used. However, the hot stamping process requires 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 price of the rotary hot stamping roller is relatively high and accounts for a large proportion of the cost of the hot stamping process. 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 also has a certain relationship with 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 One is online hot stamping.
The improvement of the chemical properties of hot stamping foil has provided a reliable guarantee for the substantial increase in hot stamping speed. Therefore, the current hot stamping process can be completed online, and online hot stamping The application of hot stamping technology will become more and more common in the future. In addition, sheet-fed folding carton printing is developing towards web printing, which also creates conditions for the online hot stamping process.
Another development trend in the hot stamping process is to stamp first and then print, that is, overprinting on the foil after stamping. The process of hot stamping first and then printing 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.
Hot stamping followed by overprinting with opaque or transparent colored inks can achieve captivating effects, provide packaging designers with endless design options, and provide designers with opportunities to fully express themselves A vast space for creative talent. </p
