Application of Digital Printing and 2D Barcode in Printing

Variable 2D barcode security is based on variable printing technology, 2D barcode technology, and database encryption technology. Speaking of variable printing, we must start with its basics - digital printing. Digital printing has been developed abroad for several decades and has just begun in China. For example, the Shanghai Commercial Printing Press Co., Ltd. has purchased XEICON, Scitex digital presses and GMC professional digital printing software in two years. A complete digital printing system.

The French XEIKON7000 digital press is a high-speed, high-precision digital press with international advanced level at the end of the 1990s. Its highest printing speed is 45 meters per minute, and the printing accuracy reaches 480dpi. It receives a file package (including database file, font file, typesetting file) through the local area network, and prints each set of data in the database in a specified format on the specified position of the page. Its own computer needs to print each page. The contents are calculated and the different contents of the database can be printed on each page. XEIKON7000 is magnetic powder printing. It converts the printing content into electric pulses. After magnetic heads are replicated, a magnetic latent image is formed on the drum. After the magnetic drum passes through the toner cartridge, the magnetized latent image absorbs the toner and the electrode wire charges the toner. Electromagnetism is used to transfer the toner image to the paper, and the ultraviolet and high-temperature processing are used to melt the toner in the image on the page, and the drum is cleaned and demagnetized to prepare the next page for printing. Because part of the toner on the paper penetrates the inside of the paper fiber due to melting, the ink layer adheres firmly to the paper surface; the other part solidifies and accumulates on the surface of the paper, forming a certain thickness of the ink layer, so when the finger print part is touched There will be a significant sense of concavity and convexity. Observing with a high magnification magnifier, you will notice that the toner is obviously piled up and arranged in an irregular pattern. This is impossible for any other printing device, so the printed matter has a good anti-counterfeiting effect. .

The XEIKON 7000 is highly automated. Eight light- and pressure-sensitive sensors are distributed throughout the machine to control the path of the paper and the quality of the print. Any erroneous actions, malfunctions and unexpected machines are automatically shut down and error messages are transmitted. Give the computer and display on the screen, this design greatly improves the printing quality and work efficiency. The printing part of XEIKON 7000 has a simple structure and is easy to maintain. According to the length of machine working time, it needs different parts of maintenance and can be divided into six levels of maintenance. The ordinary operator only requires to master the method of maintenance from one to three levels, based on the actual operation experience. The requirements for cleaning and maintenance of magnetic heads and drums are higher because they are directly related to the life of magnetic heads and drums and the quality of printed materials. Because manufacturers do not take into account the humid climate in the Chinese mainland and the room temperature of the workshop, special attention must be paid to equipment and Cooling and moisture-proof of consumables, including when the equipment is working, also need to use air-conditioning to cool the workshop, and the equipment will stop working when the room temperature is too high. XEIKON 7000 printing machine eliminates the intermediate links such as photocopying , proofing and printing in the traditional printing process, satisfies the market requirements of instant, rapid and on-demand printing, and has broad development space in the ticket printing industry.
