2015 china printing share 40%

2015 china printing share 40%  high-speed inkjet printing will account for the printing market share of 40%.According to InfoTrends forecast, by 2015, the color high-speed inkjet printing in china will account for 40% share of the digital color printing market, the fastest growing technology chinese printing industry. The quality and cost advantages brought about by technological progress, just color high-speed inkjet printing fast-growing part of the reason. Match the extent of the equipment performance printing applications, color high-speed inkjet printing press meet order demand and growth in corporate profits, and thus win the key factors in the market. Drupa 2012, a number of printing equipment suppliers have research or to launch a high-speed inkjet printer, printing format is increasing, the quality is getting higher and higher like book printing,catalog printing skill, the cost is getting lower and lower, making high-speed inkjet printing by industry overall height of great importance!
Inkjet printing inkjet principle can be divided into continuous ink-jet and on-demand inkjet two.

A continuous jet CIJ (Continuous lnk Jet)

The principle of continuous ejection frequency oscillatory pressure imposed on the ink, so that ink is ejected from a nozzle to form a uniform continuous droplet stream. At the nozzle with the synchronous variation of the electric field of a graphics photoelectric conversion signals. Ejecting droplets of selected zone in the electric field of charging electricity, when the droplet flow to continue through the deflection field, the charged droplets are deflected under the action of an electric field, the uncharged droplets continue to maintain a straight flight status. The straight flight droplet can not reach substrates and liquid collection recycling. Charged droplets sprayed onto substrates completed printing.

2. Demand jet DOD (Drop On Demand)

Demand jet printing system works When printing is required, the system of the ink inside the nozzle, applying a high-frequency mechanical force, electromagnetic, thermal shock, so that the formation of fine droplets ejected from the nozzle is controlled by computer injected into the pattern at the set. Demand jet the most widely used is a thermal inkjet technology, it relies on the the hot pulsating produce ink droplets, a heated resistance wire to the required temperature is controlled by the computer, causing the ink gas (fog) After the nozzle.

Another DOD technology is voltage-injection system, that is controlled by a computer to impose a potential on the electrically conductive material, the conductive material in the direction of the electric field generating compressed to produce expansion in the vertical direction, so that the ink ejection. Inkjet printing requires not only high-precision nozzle technology, high precision control technique, the same time required to have high purity, high concentration, high fastness, a high stability of the ink (ink) match, only the value in use.
