The printing method of corrugated boxes has always been offset printing, followed by flexographic printing. However, both printing methods have their shortcomings. The investment cost of the two Advanced Flexo Printer is high, and a plate must be developed before printing to print the image on the substrate, and the price of this plate accounts for a large proportion of the entire operating cost. In recent years, digital printing has brought impact to these two printing methods.
The process of digital printing is from computer to paper or printed matter, without any intermediary simulation or carrier intervention, and the information of the printed matter is 100% variable information, that is, the two adjacent printed matter can be completely different. There can be different layouts, contents, sizes, and even different materials. Shanghai's self-adhesive printing, but the printing quality is at least equal to the traditional printing technology, far higher than the printing technology. Therefore, on-demand, timeliness, and variability are the characteristics of digital printing. In addition, the investment cost of a general digital press can be 40% -50% lower than traditional offset or flexo printing.
Seeking the production of
flexo plate cleaning machine calligraphy and engraving printing presses, Sai Angel saw the potential of packaging printing and digital printing, so he launched a digital printing machine for corrugated paper in 2003. Gan Aishi, marketing manager of the company's Asia-Pacific region, said that China's calligraphy and calligraphy and engraving market, such as large inkjets and advertising boards, has become saturated in recent years; at the same time, they also saw the rapid development of China's packaging industry, so they developed this Printing machine-CORjet. However, because the machine is fully automatic direct printing, there will be situations where the production and the ink drying speed are different. At present, the best effect is to print corrugated cardboard. They also continue to improve the printing of other substrates.
Although the time for Sai Angel to enter the packaging industry is still short, they are very optimistic about the development prospects of this industry. However, Gan Aishi pointed out that there are still certain challenges to be faced in the future. The first is to change the thinking of Chinese users to use traditional printing methods, so they will hold more seminars to guide users in the next year; the second is the problem of plagiarism, but she It is believed that if you can add some unique technologies while imitating the printing press, it is also a way to improve the machinery.
The characteristic of CORjet is that the ink is a digital liquid transmission. Thousands of nozzles simultaneously eject very high repeatable droplets at an ultra-high speed of 25,000 droplets / nozzle / second. The Shanghai printing plant has demonstrated 15,000 droplets under laboratory conditions / Nozzle / sec production speed. The use of water-based environmentally friendly ink series has the characteristics of wear resistance, water resistance and ultraviolet resistance.
The drop-on-demand printhead developed by Aprion has considerable flexibility. Tests have proved that this type of print head is superior to other inkjet technologies in terms of working speed, service life, and ink compatibility. The above advantages make it particularly suitable for industrial use and other applications.
Compared with other inkjet technologies, Aprion drop-on-demand printheads have many advantages, including:
1) Compared with continuous inkjet, the print head has the characteristics of better quality and higher reliability.
2) Compared with thermal inkjet, the print head is compatible with a wider range of ink formulations; it can enhance the control of the amount of ink dripping and ink supply (bad control will affect the image quality); longer life; High viscosity ink.
Compared with traditional printing presses, digital printing presses based on this technology are faster, have lower cost per page, and have a competitive advantage. With the development of technology, printing quality and printing speed will reach higher standards. Gan Aishi said that in fact, CORjet can be used not only for corrugated cardboard but also for printing other materials.
