The use of inkjet printing technology (I) – ink-jet print – screen printing indu
Inkjet printing technology originated in the late 19th century, the rise in the 20th century 90 Era, the device has low cost, environmental protection and good, the field of digital printing has become one of the most abundant and wide range of technical means. It includes: small ink-jet printers, large-format ink-jet printers, ink jet printing equipment, digital printing equipment. Digital and computer technology as a product of inkjet printing covers some of the traditional printing can not be involved in the printing market, and gradually expand to a number of areas, the market prospect.
1, the basic principle of inkjet printing
Ink jet printing is a non-contact, no pressure, no printed version of the print, the system controller. Inkjet controllers, nozzles, drive mechanism composed of substrates, ink jet controller under the control of the nozzle from the nozzle in the substrates printing, color inkjet printers usually have high temperature high pressure and ambient temperature and pressure-type print printed in two ways. The former to Canon's bubble technology and HP's thermal technology as the representative, the latter Epson Advanced Micro Piezo print technology as the representative. Thermal method is by a small bubble of heat resistance, so that the surrounding Ink Evaporation, bubbles, bubble expansion pressure of ink from the nozzle to reach the substrate, after the emission of air bubbles disappear from the ink tank then were exposed to a new ink, resulting in a continuous bubble work. The Micro Piezo inkjet technology is the piezoelectric chip on the ink will mouth side of the chip, add a little current, vibration, vibration of the ink ejected by.
Second, our current situation inkjet printing technology
Inkjet printing industry in China and abroad, not far off time, but in R & D, sales and applications with the United States, Japan and other developed countries there is still a gap. Distribution in the region, mainly in the economic development of Guangzhou, Shenzhen, Shanghai and Beijing. Currently the application of inkjet printing in a polarized situation, one end is a low-end market, mostly non-use of equipment, production inkjet printer, print job market are short black and white live, plus a small amount of color live. The other end of the high-end market, practitioners inkjet printing equipment used by most digital inkjet production printing, printing is not only the short version of live color printed pieces, many of personalized, variable data printing, color printing products. Such digital printing customers pay more attention to quality and service, and printing of color have a very high quality requirements.
3, the advantages and characteristics of ink-jet printing
1, ink-jet printing is a full digital printing, traditional printing process entirely out of the cumbersome procedures, color overprinting and trapping ask for much, do not consider the set of precision, work preparation time, the market reflects the rapid , operating short production cycle time can be very high efficiency and cost-effective completion of Digital proofs and short-run production operations.
2, to achieve variable data printing and custom printing, the image information can change at any time to meet the user's short runs and personalized printing live parts needs, such as: personal albums, product descriptions, information, test marketing products, packaging samples, etc. .
3, one from India, reduce waste, Printing services More flexible, usually printed in 1000 there are advantages.
4, the number of features make it easier to introduce digital asset management, automated workflow and color management in digital integrated technology.
5, allows remote printing, transmission through the Internet to provide remote printing services, especially for trans-regional chain of quick printing.
6, the majority of non-contact inkjet printing technology printing, can be replicated in a variety of printing materials, such as a variety of goods on the production line printing of variable Coding.
7, digital web-fed inkjet printing equipment can not be paper length limit, allows large format, panoramic view of the reproduction.
Four factors that affect the quality of inkjet printing
Measure of print quality is good or bad ink-jet equipment has the following aspects:
