Advantages and Disadvantages of Hot Stamping Technology

At present, hot stamping has become an important method for surface finishing of metallic effects, and it is an effective way to enhance the visual effects of labels, paper boxes, and trademarks, and has been widely used. Hot stamping methods mainly include hot stamping and cold stamping, both of which have their own advantages and disadvantages. In practical applications, the appropriate stamping method is selected according to the specific conditions, especially when weighing the cost and quality. note.

Hot Stamping Technology

Hot stamping technology refers to the use of a dedicated metal hot stamping plate to transfer the hot stamping foil to the surface of the printing material by heating and pressing.

1. Advantages and disadvantages of hot stamping technology

(1) Good quality, high precision, hot stamping image edge sharp and sharp.

(2) The surface gloss is high and the hot stamping pattern is bright and smooth.

(3) Wide selection of hot stamping foils, hot stamping foils of different colors, hot stamping foils with different gloss effects, suitable for hot stamping foils of different substrates.

(4) The hot stamping process has a prominent advantage: it can perform three-dimensional hot stamping. Using computer numerical control engraving (CNC) method to make a three-dimensional hot stamping version, so that the hot stamping processing into a graphic with a clear three-dimensional level, the formation of relief effect on the surface of printed matter, resulting in a strong visual.

It is the hot stamping process that has many advantages as mentioned above, and it is widely used by users and consumers. However, the hot stamping process requires the use of special equipment, the need for heating devices, the need to produce hot stamping, so to obtain high-quality stamping results also have to pay a higher cost.

The price of rotary hot stamping cylinders is relatively high, which accounts for a large proportion in the cost of hot stamping processes. It is the main cost factor for hot stamping processes. In the past five or six years, the price of hot stamping cylinders has greatly reduced by as much as 50%. In the past, due to the limitation of the hot stamping speed, most of the hot stamping work was done off-line. A few years ago, the hot stamping machine's hot stamping speed did not reach 5000 sheets/hour. At present, regardless of the platform type heat, Hot stamping machine, or roller type hot stamping machine, the speed can reach 7500-12000 sheets / hour. Of course, the speed of hot stamping is also related to the type of machine used.

2. Development trend of hot stamping technology

One of the development trends of hot stamping technology in the future is online hot stamping. The improvement of the chemical properties of the hot stamping foil provides a reliable guarantee for a significant increase in the hot stamping speed. Currently, the hot stamping process has been completed online, and the application of the online hot stamping process will become more and more common in the future. In addition, sheet-fed folding carton printing is moving in the direction of web printing, which also creates conditions for on-line hot-stamping processes.

Another development trend of the hot stamping process is the first hot stamping, that is, after the hot stamping, the overprinting is performed on the hot stamping foil. The first hot post-printing process benefits from the improvement and improvement of the chemical properties of the hot stamping foil so that UV ink can be used to print on the hot stamping foil. The first hot post-printing process can provide more excellent decorative effects and enhance the visual appeal of the image.

After overprinting, opaque or transparent color inks are overprinted to achieve fascinating results, providing package designers with endless design solutions and providing designers with ample space to fully express their creative talents.
