In the past, corrugated cartons have been mainly printed by offset printing, followed by flexographic printing. However, both methods of printing have their shortcomings. The investment cost of both is high, and a plate must be prepared 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, it has been digital printing that has hit the two printing methods.
The digital printing process is a computer-to-paper or print process that does not require the intervention of any intermediary simulations or carriers, and the printed information is 100% variable information, that is, two prints that are adjacent to each other can be completely different. There can be different layouts, contents, sizes, and even different materials. Shanghai self-adhesive printing, but the print quality is at least equal to the traditional printing technology, and far more than the printing technology. Therefore, on-demand, timeliness, and variability are characteristics of digital printing. In addition, the investment cost of a typical digital press can be 40%-50% lower than traditional offset or flexo printing.
Sejangelo, who has been making printing machines for calligraphy and painting, has seen the potential of packaging printing and digital printing. In 2003, he introduced a digital printing machine specifically for printing corrugated paper. According to Gan Qishi, marketing manager of the company's Asia-Pacific region, China's calligraphy and painting market, such as inkjets and advertising boards, has become saturated in recent years; at the same time, they also saw the rapid development of the Chinese packaging industry, and developed this product for the packaging industry. Printing machine - CORjet. However, because this machine is a fully automatic direct printing, the production and drying speed of the ink may be different. Now, printing corrugated board is the best. They also continue to improve the printing effect of other substrates.
Although the time for Sai Angels to enter the packaging industry is still short, they are very optimistic about the development prospects of this industry. However, Gan poetry pointed out that there are certain challenges that need to be faced in the future. The first is to change the thinking of Chinese users to use traditional printing methods. Therefore, they will hold more seminars to guide users in the coming year; second is plagiarism, but she It is believed that adding some unique technology to the imitation of printing presses is also a way to improve machinery.
The CORjet features an ink that is digitally fluidized, with thousands of nozzles spraying highly repeatable droplets at the ultra high speed of 25,000 droplets/nozzle/sec. The Shanghai Printing Laboratory has demonstrated 15,000 droplets in laboratory conditions. / Nozzle / second production speed. The use of water-based environmental protection ink series, with wear-resistant, water-resistant, UV-resistant and so on.
The drop-on-demand print head developed by Aprion has a very high degree of flexibility. Tests have shown that this type of print head is superior to other ink jet technologies in terms of working speed, service life, and ink compatibility. The above advantages make it particularly suitable for industrial applications and other applications.
Compared to other inkjet technologies, Aprion Drop On Demand printheads have many advantages, including:
1) Compared with continuous inkjet, the printhead has better quality and higher reliability.
2) Compared with thermal inkjet, the print head can be compatible with a wider range of ink formulations; it can enhance the control of ink drop amount and ink supply speed (bad control will affect image quality); longer service life; can be used High viscosity ink.
Compared to traditional presses, digital presses based on this technology are faster, have lower cost per page and have a competitive advantage. With the development of technology, the printing quality and printing speed will reach higher standards. Ganzi poetry, in fact, CORjet not only can be used for corrugated cardboard, but also print other materials.
