In order to attract consumers' attention and stimulate consumers' desire to buy, the current packaging of goods is becoming more and more beautiful and more dazzling. When customers buy goods, their eyes stay on each product for more than 1.8 seconds. A medium-sized supermarket has no less than 30,000 kinds of goods. In order to grab customers' eyes, novel and unique packaging has become an important business. The killer. When you shop or hang out in a supermarket or shopping mall, you will find that metal effects and holographic effects are becoming more and more widely used in packaging products.
Hot stamping technology application
Mr. SammcElree, Product and Sales Manager at KURZ Transfer Products, states: “The packaging of perfumes, chocolates, chewing gum, film, CDs, DVDs, cigarettes and foods is as high as the fine labels of wine, champagne and spirits. The design has become more and more popular as the competition in the market has intensified. In general, the eye-catching packaging and the use of holographic foils to achieve brand recognition.
At present, hot stamping has become an important metal surface finishing method, which is an effective way to enhance the visual effects of labels, cartons, trademarks, etc., and is widely used. The hot stamping method mainly includes hot stamping and cold stamping, both of which have their own advantages and disadvantages. Therefore, in practical applications, the appropriate hot stamping method should be selected according to the specific situation, especially in weighing the cost and quality. More attention should be paid.
Hot stamping technology
Hot stamping technology refers to the transfer of hot stamping foil to the surface of the printing material by means of a special metal hot stamping plate by heating and pressing.
1. Advantages and disadvantages of hot stamping technology
The advantages of hot stamping technology mainly include the following points.
(1) The quality is good, the precision is high, and the edge of the hot stamping image is clear and sharp.
(2) The surface gloss is high, and the hot stamping pattern is bright and smooth.
(3) Hot stamping foil has a wide selection range, such as hot stamping foil of different colors, hot stamping foil with different gloss effects, and hot stamping foil suitable for different substrates.
(4) The hot stamping process also has a prominent advantage, that is, it can perform three-dimensional hot stamping. The three-dimensional hot stamping plate is made by computer numerical control engraving and engraving (CNC), which makes the image printed by hot stamping have obvious three-dimensional layer, and forms a relief effect on the surface of the printed matter, and produces a strong visual impact effect. Three-dimensional hot stamping gives the package a unique touch.
It is precisely because of the many advantages mentioned above that the hot stamping process has been favored by users and consumers, and the application is very extensive. However, the hot stamping process requires special equipment, requires a heating device, and needs to make a hot stamping plate. Therefore, obtaining a high-quality hot stamping effect also means a higher cost.
Mr. Chris Corbett, International Sales Manager of ITWFoilmark, pointed out that the high price of rotary hot stamping cylinders and the large proportion of hot stamping process costs are the main cost factors of hot stamping process. At the same time, he also pointed out that in the past five or six years, the price of hot stamping cylinders has been greatly reduced, and the drop rate is as high as 50%. In addition to reducing the cost of hot stamping cylinders, hot stamping system suppliers have also challenged the hot stamping speed limit. In the past, due to the limitation of hot stamping speed, most of the hot stamping work was done offline, and the situation is very different now.
A few years ago, the hot stamping speed of hot stamping machines was less than 5,000 sheets per hour. At present, whether it is a platform type hot stamping machine or a drum type hot stamping machine, the speed can reach 7500 to 12000 sheets per hour. Of course, the speed of hot stamping has a certain relationship with the type of machine used. The continuous increase in production speed has greatly reduced the cost of hot 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 the hot stamping foil provides a reliable guarantee for the substantial increase in the hot stamping speed. Therefore, the hot stamping process has been completed online, and the application of the inline hot stamping process will become more and more common in the future. In addition, sheetfed folding carton printing is moving in the direction of web printing, which also creates conditions for the inline hot stamping process.
Another development trend of the hot stamping process is to apply hot stamping, that is, hot stamping and then overprinting on the hot stamping foil. The hot stamping process also benefits from the improvement and improvement of the chemical properties of the hot stamping foil, so that UV ink can be used for printing on hot stamping foil. The hot stamping process provides a more decorative effect and enhances the visual appeal of the image.
Overprinting and opaque or transparent color inks can achieve fascinating effects, provide packaging designers with endless design solutions, and provide designers with ample space to fully express their creative talents.
