How is the laser anti-counterfeit label printed?
The production and processing of customized laser anti-counterfeiting labels is also called holographic anti-counterfeiting labels. It is an anti-counterfeiting label that uses laser color hologram plate-making technology and molded copy technology. The achievable plate-making technology includes: dot matrix dynamic light, one-time special laser film, 3D optical miniature background, colorful optical random interference, Chinese and English uranium abbreviated text, etc.; its characteristics are: the label pressed from the same template is the same, but the template is affected by various parameters and environmental conditions during the photolithography process, which is not quite It is possible to make two identical templates, which is also one of the most important anti-counterfeiting features of laser marking.
The die cutting of laser anti-counterfeiting label printing is a half-cut through process, that is, only the surface material is cut through and the backing paper is retained. Divided into two processing methods: such as flat die cutting, suitable for all kinds of label printers, manual plate making, low cost, short plate making cycle, but low viscosity, suitable for short-run printing processing. At present, almost all domestic label factories adopt flat die-cutting methods. The other is circular die-cutting, which is applied to circular press-round label equipment. It has fast speed and high die-cutting viscosity, which is suitable for long printing. The disadvantage is that the plate-making cost is large and the cycle is long. Anti-counterfeiting self-adhesive label printing-anti-counterfeiting label screen printing anti-counterfeiting mainly refers to anti-counterfeiting for the coated part and part. It is recommended that the coating part of the screen printing anti-counterfeiting should not be coated as much as possible, because the cost of the coating is high and it is not easy to cut, varnishing is the best way; laser anti-counterfeiting label printing when making self-adhesive labels, try not to use varnishing as a whole , Part of it will do.
Laser anti-counterfeiting label printing. The thickness of the screen mesh affects the thickness of the coating, and the thickness of the thinner affects the appearance of the coating. The screen printing anti-counterfeiting technology of laser anti-counterfeiting label printing uses water-based screens for dripping anti-counterfeiting, and the others are generally oily. The screen-printing anti-counterfeiting screen meshes are generally 250-350 meshes. In theory, the larger the screen-printing screen meshes, the stronger the effect and the thicker the coating. Laser anti-counterfeiting label printing and silk screen anti-counterfeiting have been found in actual use, the thicker the ink, the more detailed the pattern of the silk screen. If the dilution is not enough, it may also crust. Silk screen anti-counterfeiting is related to typesetting and design. The larger the typesetting space, the better the position can be adjusted during screen printing. The laser anti-counterfeit label printing screen printing is also related to the weather. Too much humidity or too high temperature will affect the effect of screen printing. Generally, slow drying water or extra slow 783 is required when the temperature is high, and the drying water should be speeded up when the temperature is low.
Laser anti-counterfeiting label printing should pay attention to the customer’s individual label requirements and the coding has a certain relationship, it does not matter if the coating is printed on the coating thin spots; if the coating If there is no printing, the coating should be thicker; in addition, the font should be as clear as possible but the strokes should be as fine as possible when coding. The glue water of the laser anti-counterfeiting label trademark is water glue and hot melt glue. Because the hot melt glue equipment has the advantages of small size and low price, and the hot melt glue is environmentally friendly, intensive, repeated bonding, recyclable and easy to operate in the operation process Such advantages make it more and more widely used in the label field. The process of hot melt adhesive equipment is composed of several parts such as unwinding-coating-cooling-compounding-winding. The laser anti-counterfeiting label printing silk screen is related to the order of label placement: those with serial numbers and those without serial numbers should be placed separately. Laser anti-counterfeiting label printing-screen printing should pay attention to the material problem, different materials have different inks and methods; when selecting raw materials for laser anti-counterfeiting label printing, they will choose high-quality anti-counterfeit self-adhesive materials that are qualified in various physical and chemical indicators. Failed materials are cheap and adopted. Inferior raw materials are inherently unstable in quality, and there is a greater chance that the equipment cannot be processed normally, which wastes resources and manpower, and also causes losses to customers and loses customers. Therefore, the selection of raw materials has strict standards. You can rest assured to buy and place orders.
There is a strong need for more research on , in order to be able to provide strong and conclusive evidence of their sticker holograma effects. However, recent studies have provided valuable insights into how the intake of may result in improved valid hologram sticker.
Guangzhou LG Printing Technology Co., Ltd will accomplish this by exceeding the expectations of our customers while conserving resources and preserving the quality of the environment.
The hologram serial number stickers custom printed hologram stickers is also available as a sticker hologram.
