RFID tags bring new opportunities to printing technology innovation

RFID is the abbreviation of radio frequency identification technology. RFID tag is a typical combined application of substrate and electronic technology, which can realize the communication between substrate and computer. RFID tag refers to the electronic chip containing product information and related antenna and power supply on the substrate, which receives radio signals such as microwave from the special reader through the antenna, and reflects the number 1 contained in the tag chip According to the experimental temperature, it can be divided into high temperature normal atmospheric temperature. According to the information, the cryogenic experimental machine is finally sent to the main computer for processing, so as to realize the non-contact identification, search and management of products, breaking the limitations of traditional bar code identification, and can be widely used in supermarkets and logistics. Storage and other application fields. It is understood that Wal Mart, the world's largest retailer, is vigorously promoting the application of RFID tags

rfid tag is usually composed of printing layer, chip layer and bottom layer, but this kind of RFID tag has high production cost and is difficult to be truly popularized and applied. Therefore, using conductive ink as a new processing technology has become the main choice of label production. Conductive ink is a kind of special printing ink that allows current to flow. Printing ink has high requirements for formula. It can print wires and antennas on different substrates. The printed antenna can receive the microwave signals emitted by the reader, such as F in the United States to obtain parameters: tensile strength (RM) and elongation at break (at). Lint LNK is the main manufacturer of conductive ink. RFID tag production with conductive ink is a high-speed printing process with relatively low cost and high production efficiency

with the improvement of the complexity of printing operations, people's demand for low-cost and high-quality printing materials increases. Integrating the advantages of various printing methods to form a combined printing technology with complementary advantages will be a development direction of printing in the future. The same printing material will be completed by combining a variety of different printing processes. Combination printing can be the combination of offset printing and inkjet printing, flexo printing, gravure printing, offset printing and silk printing, or the combination of digital printing and any traditional printing

the most typical example is the combination of offset printing and digital printing in direct mail or modern bill printing. First, offset printing is used to print static image and other page information, and then digital printing is used to print personalized data, text, graphics or images on each page. Another typical application is the combination of silk printing and flexographic printing or gravure printing in label printing. For example, when the label contains a large area of very bright color blocks, silk printing is used to complete the printing of color blocks, and then other information in the label is printed through flexographic printing, gravure printing or offset printing, which can not only reduce the printing cost, but also achieve the ideal printing effect

the development trend of offset press in the future is larger volume and better printing quality. The printing speed is faster, and more automatic process control can be realized. Automatic process control includes plate replacement, blanket cleaning, ink presetting, closed-loop color control, and flexible addition of required standards; By connecting the automatic cutting device at the front end of the sheet fed printer, the web paper can be automatically cut into sheet fed paper and then printed on the machine

the printing quality of various mature digital printing technologies, especially the digital imaging technology based on toner, has approached that of traditional offset printing. Digital printing technology is the basis for the realization of many ways, such as computer direct printing, short edition printing, on-demand printing, personalized printing, publishing before printing, and variable data printing. These printing needs are almost impossible to realize in the era of traditional printing. The maturity of digital printing technology will promote the emergence of more new commercial printing service modes and printing forms. In the future, printing enterprises will no longer say "no" to customers, and any printing requirements will be met
