Laser ink-jet printing technology

Abstract

The present invention relates to the laser ink-jet printing technology. In the prior art, a laser printer is fast in printing speed, high in printing quality, high in printer cost and expensive in consumables, while an ink-jet printer is low in printer cost, cheap in consumables and slow in printing speed. The above laser ink-jet printing technology integrates the laser printer and the ink-jet printer, wherein the laser is modulated by utilizing a laser scanning system. Meanwhile, the laser deflection is controlled, so that the laser is enabled to shoot into each small ink chamber of an ink-jet head. The photoinduced deformation of components occurs inside the small ink chamber, and the size of the interior of the small ink chamber changes. Each small ink chamber inside the ink-jet head injects ink drops, so that the on-demand ink-jet printing is realized. Meanwhile, based on the ultrasonic focusing generated due to the acoustic effect of the periodic intensity-modulated laser, the ink-jet is realized. Since one part of the ink-jet head is free of any circuit, the requirement on the manufacturing process of the ink-jet head is relatively low compared with the thermal bubble technology and the piezoelectric inkjet technology. The structure is much simpler compared with the laser printer, and the printing speed is faster. Meanwhile, page amplitudes can be conveniently manufactured, and the high-precision printing is realized more easily. The use cost is low.

Description

technical field [0001] The invention relates to an inkjet printing technique for ejecting ink droplets. This inkjet printing technology is developed on the basis of combining laser printer technology and inkjet printer technology. Background technique [0002] Dot matrix printers, inkjet printers and laser printers currently occupy the mainstream printing position in the market. Dot matrix printers are mainly used for ticket printing, and commonly used printers are mainly laser printers and inkjet printers. [0003] The so-called inkjet printer is to form text or image by spraying ink droplets onto the printing medium. The early inkjet printers and the current large-format inkjet printers all use continuous inkjet technology, while the current popular inkjet printers generally use random inkjet technology. According to the driving method of inkjet printing, it is mainly divided into thermal bubbles type, piezoelectric, ultrasonic and electrostatic. [0004] Inkjet printe...
