FAQ
Q1:
What are the differences and advantages and disadvantages of hot stamping and cold stamping?
A1:
Both hot stamping and cold stamping belong to hot stamping (hot stamping) technology. This article gives a detailed introduction to the differences and advantages and disadvantages of hot stamping and cold stamping.
When you shop or stroll in a supermarket or shopping mall, you will find that the hot stamping effect is more and more widely used in packaging products. Hot stamping and cold stamping are both used to make the product packaging bright and dazzling, attract consumers' attention and stimulate their desire to buy. Because when customers choose goods, their eyes will not pass over each product for more than 2 seconds, and a medium-sized supermarket also has more than 30,000 products. Obviously, hot stamping and cold stamping help to grab customers' attention and are important killers for merchants.
As an important metal effect surface finishing method, hot stamping is an effective way to enhance the visual effects of products such as trademarks, cartons, and labels, and is widely used. The two main hot stamping methods, hot stamping and cold stamping, have their own advantages and disadvantages. In practical applications, the appropriate hot stamping method should be selected according to the specific situation, mainly based on cost and quality considerations.
Hot stamping technology
1. Principles of hot stamping technology
Using a special metal hot stamping plate, the hot stamping foil is transferred to the surface of the substrate by heating and pressurizing.
2. Advantages of hot stamping technology
(1) Good quality, high precision, clear and sharp edges of the hot stamping image.
(2) High surface gloss, bright and smooth hot stamping pattern.
(3) A wide range of hot stamping foils can be selected, such as different colors or different gloss effects, and hot stamping foils suitable for different substrates.
(4) Three-dimensional hot stamping can be performed. It can give the packaging a unique touch. Moreover, the three-dimensional hot stamping plate is made by computer numerical control engraving (CNC), so that the three-dimensional layers of the hot stamped image are obvious, forming a relief effect on the surface of the printed product and producing a strong visual impact.
3. Disadvantages of hot stamping technology
(1) Hot stamping process requires special equipment
(2) Hot stamping process requires heating device
(3) Hot stamping process requires heating device and needs to make hot stamping plate. Therefore, hot stamping can achieve high-quality hot stamping effect, but the cost is also higher.
TAMPRINTER's many years of experience summary: The price of rotary hot stamping roller is relatively high, accounting for a large part of the cost of hot stamping process. However, in the past five or six years, the price of hot stamping roller has been reduced by up to 50%. In addition to reducing the cost of hot stamping roller, TAMPRINTER has also greatly improved the speed limit of hot stamping. In the past, due to the limitation of hot stamping speed, most hot stamping work was completed offline, and the hot stamping speed of hot stamping machine could not reach 5,000 sheets/hour. Now Hanyuan uses platform hot stamping machine and roller hot stamping machine, the speed can reach 7,500 to 12,000 sheets/hour. The continuous improvement of production scale and production speed has greatly reduced the cost of hot stamping.
Cold stamping technology
1. Principle of cold stamping technology
The cold stamping process has good comprehensive performance and convenient online processing capabilities. Cold stamping requires two printing units. The first unit transfers the exclusive sticky ink to the offset printing plate and makes it firmly adhere; the second unit transfers the graphic information to the sticky coated photosensitive layer. The research and development of the cold stamping process has enriched the performance of printing, added new design schemes, beautified fonts and can more perfectly handle the level of details. Due to the platemaking process of letterpress printing, many details cannot be properly copied to the printing plate, resulting in low printing accuracy. Compared with the online integrated operation of the online cold stamping process, offline thermal printing is relatively low in cost but not high in accuracy. The biggest advantage of online cold stamping over thermal transfer is its more accurate overprint accuracy. Unlike thermal transfer, the transfer device in the cold stamping process is installed on the bottom coated photosensitive layer, which can ensure that the information is directly printed after transfer without too much problem. The development of in-line cold foil technology and its exclusive overprinting process has brought new performance effects and enriched the content of pre-press design. At the same time, this process has higher returns and lower storage costs than traditional thermal transfer, and it is an in-line operation. This is the development trend of the industry in the future. The in-line cold foil process will become a very strong market competitiveness. In the thermal transfer process, the transfer system usually consists of a carrier material to form a transfer layer, which is generally divided into two layers in actual printing. This situation is very different from the in-line cold foil process. After overprinting, almost all color adjustments have been completed, so that the ink can be properly transferred to the coated photosensitive layer without stratification, which affects the printing quality. In the cold foil process, the color is no longer predetermined, but the complete printed image is transferred to the coated photosensitive layer. This transfer method is completely different from the thermal transfer process. Due to the process requirements, it is difficult to ensure the registration accuracy of the latter, and the phenomenon of ink stratification often occurs. Therefore, in the cold foil process developed later, special attention is paid to the registration link. Relatively accurate overprinting is achieved through the intervention of the coated photosensitive layer, which is suitable for traditional inks, UV inks and mixed inks. Three-dimensional effect. In terms of visual communication, cold stamping technology has made new contributions. The three-dimensional expression effect cannot be achieved through traditional thermal transfer.
2. Advantages of cold stamping technology
(1) No expensive special stamping equipment is required.
(2) Ordinary flexible plates can be used, and there is no need to make metal stamping plates. The plate making speed is fast, the cycle is short, and the production cost of the stamping plate is low.
(3) The stamping speed is fast, up to 450fpm.
(4) No heating device is required, saving energy.
(5) A photosensitive resin plate can be used to simultaneously complete the stamping of the halftone image and the solid color block, that is, the halftone image and the solid color block to be stamped can be made on the same stamping plate. Of course, just like printing the halftone and solid color blocks on the same printing plate, the stamping effect and quality of both may be lost to a certain extent.
(6) The application range of the stamping substrate is wide, and it can also be stamped on heat-sensitive materials, plastic films, and in-mold labels.
3. Disadvantages of cold stamping technology
(1) Stamping cost and process complexity: Cold stamping images and texts usually require lamination or varnishing for secondary processing and protection.
(2) The aesthetics of the product is relatively reduced: the high-viscosity adhesive applied has poor leveling and is not smooth, which causes diffuse reflection on the surface of the cold stamping foil, affecting the color and gloss of the stamped images and texts.
TAMPRINTER believes that although the cold stamping process cannot achieve the high precision and high definition of the hot stamping process, cold stamping technology can bring many advantages to flexographic printers, including: less initial equipment investment, lower plate making cost, faster stamping speed, can be completed online on the printing press, and can be stamped on materials that are not suitable for hot stamping (such as films without a base, PET and plastic bags, etc.).
On films and non-absorbent paper materials, cold stamping technology can achieve the best stamping effect. On the contrary, when cold stamping is performed on porous materials with strong permeability, the effect is not very ideal. At present, cold stamping technology has become a strong competitor of hot stamping technology, and cold stamping technology is expanding from the field of narrow-width flexographic printing to other printing processes, such as wide-width flexographic printing, letterpress, web offset printing and sheet-fed offset printing.
Cold stamping technology provides new opportunities for printing companies. Its biggest advantage is low investment, or even no investment at all. Another outstanding advantage is high cost performance, which is also the biggest selling point of cold stamping technology. As an industry insider said: "For customers, cold stamping technology has a high cost performance, which can help customers increase the added value of products and is very economical." In addition, since cold stamping technology does not require the production of expensive stamping plates, it is very suitable for short-run jobs, labels and proofing production with low quality requirements. However, compared with hot stamping technology, cold stamping technology still has certain defects in quality, which needs to be further improved. Therefore, cold stamping technology is not very suitable for the processing of high-quality packaging and label products.
In short, the differences and advantages and disadvantages between hot stamping and cold stamping are relatively obvious. In actual production, should we choose hot stamping technology or cold stamping technology? The answer is: it depends on the specific situation. Hot stamping technology can achieve the best stamping quality and effect, but the cost is higher. Although the quality of cold stamping is also good, it is inferior to hot stamping, but the cost is lower. No matter which stamping technology you use, you should pay attention to both of them, because the price of hot stamping is constantly decreasing, while the quality of cold stamping is constantly improving. Both stamping technologies are in constant progress and development.
Q2:
What is the difference between thermal transfer and hot stamping? Everyone who is engaged in special printing has this doubt.
A2:
First of all, let's talk about thermal transfer.
As the name suggests, thermal transfer is to achieve the transfer of coating by heating. It is a new printing process that has been introduced from abroad for only more than 10 years. Thermal transfer is widely used. The transferred objects include products of various substrates such as fabrics, plastics, ceramics, glass and metals. The main application areas include cosmetics, toys, electrical appliances, building materials, gifts, food packaging, etc.
Due to the wide range and diversity of application areas, thermal transfer has many classifications. According to the production method of thermal transfer film, there are mainly two different thermal transfer methods, namely thermal transfer and digital thermal transfer. Thermal transfer is to print the pattern on the transfer carrier such as PET through a special gravure printing machine by making a gravure electric engraving plate. After the pattern is printed, the product is directly transferred on the thermal transfer machine. This transfer film production method has high production efficiency, but the initial production cost is also very expensive. It is mainly suitable for large-scale product applications. Digital thermal transfer is to print the pattern on the transfer paper through special thermal transfer printing instructions, and transfer the product to the substrate through a heat press or other transfer machine. Compared with thermal transfer, this method has lower cost and simpler pre-preparation, but limited production efficiency, and is mainly used for some small-batch products.
Now, as people's requirements for clothing patterns are becoming more and more personalized, the patterns printed on T-shirts are becoming more and more abundant, and a large part of these patterns use thermal transfer technology. The application of thermal transfer on clothing can be divided into two types: sublimation transfer and film transfer. Sublimation transfer film uses thermal sublimation ink during production. During transfer, the ink is directly embedded in the fabric fiber, with high fastness and sharp colors, which is more suitable for colorful pattern transfer printing. Film transfer contains colloid in the transfer paper, and the pattern is bonded to the fabric through the adhesive layer by high temperature and high pressure. The colloid pattern printed with imported transfer paper and ink is very thin, breathable, crack-proof, washable and non-falling.
Now let's talk about hot stamping.
Hot stamping is also a way to transfer the coating to the substrate by heating and pressurizing. In this way, hot stamping can only be regarded as a type of thermal transfer, but just because it contains a gold character in the middle, the products made by it are completely different from the thermal transfer effect. Thermal transfer usually transfers patterns, and most of these patterns are achieved by printing with ink, while hot stamping mostly presents metallic color effects such as gold, silver, brown, coffee, and blue. The hot stamped products show obvious metal brushed, bright silver, and reflective effects, making the products look more upscale, and are usually used for some local decoration.
As for hot stamping paper, it can be divided into gold and silver foil, brushed foil, laser foil, pigment foil, and other foil films for various special purposes according to the different products. According to the different hot stamping substrates, the glue of hot stamping paper is also very different. For example, ABS, PA, PP, PC plastics, fabrics, paper, OPP coating, wood, leather, etc. all require special formulas and glue coatings.
In short, hot stamping should be included in thermal transfer, but because of the special effect of hot stamping, hot stamping has higher technical requirements than thermal transfer, and the production process control is more difficult. Well-known hot stamping paper manufacturers are concentrated in a few manufacturers such as Kurz in Europe and Toyo, Liguang, Murata, OIKE, etc. in Japan, which is a step up from thermal transfer to some extent.
