With the rapid development of digital printing, many brand manufacturers have also realized the popularity of digital printing equipment, especially the digital printing press produced by OSI, Canon, HP and Xerox has been highly evaluated by the industry. However, due to the two key factors of "digital printing cost" and "printing effect", digital printing machine has limited its wide application in printing plants. The cost of digital printing and the effect of digital printing are contradictory in many models of digital printing presses, and it is difficult to have both, which is the ultimate goal that brand manufacturers have been constantly improving.

Why can't we achieve the offset effect of traditional printing, as long as we compare the working principle of ordinary digital printing press and traditional offset printing press, we can find the problem. The basic reason is that traditional printing press penetrates paper medium through electronic ink, while digital printing press mostly melts toner into paper medium through high temperature fixing.

Can be comparable to offset printing effect of the digital printing press, the current market mainly to OSI digital printing press and HP indigo. The most important reason why these two digital printing presses can distinguish themselves from other brand machines in printing effect is the application of electronic ink technology. The following are the two kinds of electronic ink technology:

1. Osco printing technology

2. HP Indigo electronic ink technology, namely HPElectroInk

What is HP Indigo electronic Ink Technology

HP Indigo Electronic Ink Technology, or HPElectroInk, is a unique liquid ink liquid EP that combines the advantages of digital printing with the quality of liquid ink. HPElectroInk is a type of charged pigmentation based particle suspended in a liquid. Similar to other digital printing technologies, i.e. dry EP or xerography, HPElectroInk electronically controls the position of the printed particle to enable digital printing. But unlike dry EP, HPElectroInk particles are very small, just one to two microns in size. HPElectroInk is supplied to customers in concentrated form and is loaded into printers in a "pollution-free" canister package. Inside the equipment, it is fully mixed and diluted with the image oil in the ink bed to form a mixture of the image oil and ink particles for printing.

HP Indigo electronic ink technology imaging principle

Firstly, the imaging board is uniformly charged, and then the laser head uses the laser beam to discharge on the imaging board according to the dot matrix format of the color after RIP. The point potential of the imaging board becomes zero, and the electronic ink of the color will be attached to the imaging area of the imaging board under the action of electric field force to form the image layer. The image layer is also transferred to the blanket by the potential difference between the imaging drum and the blanket drum. The electronic ink is partially dissolved after heating on the blanket, transferred to the substrate by pressure, and then cured and attached to the substrate. The imaging process for other colors is the same, and the color conversion technology is implemented on a set of rollers.

How does HP Indigo electronic Ink Technology support the performance required for high quality color digital printing

The size of the particles in the liquid container gives the image a high resolution, even shine, sharp edges, and a thin layer that binds tightly to the paper so it can produce perfect results.
