    The application of identification technology is gradually going deep into every corner, from heavy machinery to a wire, it is inseparable from product identification This technology is also widely used in plastic packaging containers, plastic films, plastic pipes, wires and cables, plastic parts and other products At present, inkjet printing technology mainly includes inkjet printing technology and laser inkjet technology Inkjet printing technology inkjet printing technology is also known as non-contact printing According to different working principles of inkjet printer, it can be divided into continuous inkjet printer and on-demand inkjet printer The continuous jet coder is called CIJ type for short It is used to spray the ink from a single nozzle under pressure, and it breaks after the crystal concussion to form ink dot After charging and high-pressure deflection, the ink dot is scanned on the moving object surface to form a character Most industrial inkjet systems use CIJ technology, which can reach a speed of 1000 feet per minute, much faster than on-demand inkjet, but the image quality is also lower than the application of the latter technology CIJ printing equipment manufacturers such as Domino and Videojet are in this field The ink-jet printer on demand is called DOD type for short The nozzle of the ink-jet system is composed of several high-precision valves When spraying words, the valves corresponding to the characters are opened and closed quickly The ink is ejected by the internal constant pressure, forming characters or graphs on the moving surface A digital signal on paper produces a drop of ink, not a stream of ink, which can produce an effect close to the photographic quality DoD's printing speed is between 100 and 300 feet per minute At present, many companies are developing high-speed DOD printing equipment for packaging purposes Compared with ink jet printing technology, laser jet printing technology is a more advanced technology This technology is mainly through burning and etching to achieve inkjet Burning, that is, laser sends out enough energy to remove the surface layer of plastic materials, such as ink on the surface of printing and packaging Etching, that is, the use of appropriate laser energy to make plastic material surface part of the melting, forming a groove After focusing, the extremely fine laser light speed is like a knife, which can remove the material on the surface of the object point by point, without mechanical extrusion or mechanical stress, so it will not damage the processed object In addition to the general information marking function, the anti-counterfeiting function of laser jet code technology is more significant The application of laser jet code technology in the Chinese market is just beginning, but because of its high reliability, low operating cost, simple installation and operation, and precise bar code printing, it will win a broader market In this field, Shenzhen Han's Laser Technology Co., Ltd is one of the few leading enterprises in China At present, the laser marking machines produced by the company mainly include YAG series and CO2 series, which are suitable for marking ABS, epoxy resin, PVC, bulletproof glue, polyurethane, glass and other materials Compared with the common printing methods such as pad printing or silk screen printing, the inkjet printer has the advantages of non-contact printing, high speed, low cost, instant printing, programmable and changing the printing content at any time It is more and more favored by plastic product suppliers Nowadays, plastic has become one of the main packaging materials, which is widely used in the packaging of food, beverage, tobacco, cosmetics and other products Most of these plastic materials are PVC, PE and pet, which are the main printing objects in the packaging field of inkjet printer Packaging materials require that the effect of inkjet printing is not only clear, but also beautiful Since the non-contact inkjet and laser machine do not touch the product surface in the process of inkjet printing, the inkjet printer can perform the task excellently, whether it is the regular or irregular object surface, whether it is the round, square or rough surface In addition, plastic film is widely used in the packaging of products If it is squeezed, the film will be damaged to a certain extent, which directly affects the aesthetic degree of packaging The use of non-contact inkjet technology, there is no such worries For example, the semiconductor pumped laser marking machine (dp-r75) of Da's laser can be directly marked through the plastic film on the outer package of cigarettes without damaging the film As food, beverage, tobacco and other products are closely related to life, the requirements of packaging materials for health are relatively high Laser marking technology has attracted great attention in the application of packaging materials because it can ensure the cleanness of products and production environment without using ink for marking Domino company recently launched s200b scoring laser printer mainly for PET material At present, laser printer companies on the market can provide pet surface material identification scheme, but because PET material itself is relatively transparent, when laser is printed on it and cannot change color, the effect is not significant and difficult to identify S200b marking laser jet code machine combines "blue tube technology" with laser jet code machine, making the coding color white, showing crystal texture and clear effect There are many products in the plastic pipe and plastic pipe industry, including drainage pipe trough, aluminum plastic pipe, composite pipe and rubber hose Some of the pipes have been in high temperature and high heat environment for a long time, so it is required that the logo itself has strong resistance to sunlight and high temperature environment, that is, to ensure the durability of the logo In addition, the high extrusion rate of plastic pipe also requires that the printing speed can be synchronized, while the small pipe needs flexible and sophisticated printing technology cooperation The equipment of the company can meet these special requirements Its small character ink inkjet printer series is suitable for operation in high temperature and high heat production environment The inkjet is clear, stable and wear-resistant, and the size of the printed character Zui can be up to 0.8mm At the same time, the inkjet printer has the function of automatic meter counting, which can print continuously and instantly without affecting the continuous operation of the whole production process Wire and cable code spraying technology is also widely used in wire and cable industry Cable and wire products are difficult to identify brands or trademarks from the appearance Through the spray printing of product specifications and factory name and logo, they can quickly identify genuine products The requirements of this product for identification are: easy to distinguish, not easy to wear, and has good chemical resistance and UV resistance There are many inkjet devices on the market that can meet these conditions Moreover, the angle and time allowed for spray printing are very free: it can be a 360 degree spray printing angle, or spray printing at the bottom, side or top of the product; spray printing can be carried out no matter when the raw material is extruded or when various cables are wound, no matter on the high-speed assembly line or on the independent pallet Due to the advantages of high speed and low cost, ink-jet printing equipment is widely used in the market As for the ink-jet printing equipment, the printing effect is closely related to the ink performance Nowadays, consumers demand faster drying speed, better anti-counterfeiting performance and more environmental protection The production speed of the fast drying production line is increasing, which needs the cooperation of fast drying ink For example, in the processing and production of cigarette packs, the ink is dried immediately after being sprayed on the product surface, and firmly attached to the product surface, and will not be transferred to other positions and the surface of soiled objects, which can ensure that the identification of each printed product is clear, complete and easy to distinguish, does not affect the whole production process, and effectively reduces the failure time The anti-counterfeiting function of anti-counterfeiting products has been paid more and more attention by businesses As the carrier of product identification, ink also undertakes this task A UV visible anti-counterfeiting ink appears on the market, which has better anti-counterfeiting property This kind of ink will not show in normal light, only in the ultraviolet light can be seen There are many researches on small character anti-counterfeiting invisible ink in China, but few on large character anti-counterfeiting ink When Beijing saiteng Power Technology Co., Ltd developed the hand-held inkjet, it used the big character anti-counterfeiting invisible ink, which made the hand-held inkjet play an important role Large character anti-counterfeiting invisible ink not only has high filtering accuracy, fast drying speed and strong adhesion, but also has the special anti-counterfeiting function of displaying blue light under ultraviolet irradiation Environmental protection is also a topic of great concern to the public Ink and solvent are highly volatile substances, which will produce more chemical toxic residues and pollute the environment Especially for food packaging, the environmental protection of ink is more important Its chemical composition and smell may penetrate into food through film and packaging, which may harm human health In order to eliminate this problem, the United States even banned the use of inkjet on the inner packaging of drugs At present, domino, Viagra and other companies pay great attention to the development of environmental ink In addition, in the field of food packaging, ink is also required to be edible for printing directly on the surface or inner packaging of food For those foods that need to be refrigerated, it is required that the mark can be kept unchanged after the food is refrigerated at about 0 ℃, so the low temperature resistance of ink is also very important At present, the development of China's logo industry is in the ascendant with a very high growth rate At the same time, the market requirements for logo technology are also changing The reliability and stability of the inkjet printer will be an important trend in the future The speed of domestic plastic product production line is increasingly high, and the market of inkjet printer products with rapid printing performance is undoubtedly broader.
