  • Publication number: 20210197572
    Abstract: In an inkjet laser printing system and method, the method includes: obtaining a printing instruction; moving a printing substrate in a printing area according to the printing instruction; moving an ink cartridge to a preset position relative to the printing area; controlling the ink cartridge to jet ink droplets to the printing substrate in the printing area; and conducting laser beam irradiation on the ink droplets in the printing area, to cure the ink droplets jetted on the surface of the printing substrate. Water-based ink and ink droplets are rapidly cured by means of a laser beam and melt into a plastic surface, and are applied to a plastic substrate for inkjet printing, so as to eliminate a previous restriction that oil-based ink is required for inkjet printing on plastics, and to reduce the ambient air pollution caused due to use of the oil-based ink.

  • Patent number: 10549542
    Abstract: Disclosed are a laser printer for pathological embedding cassettes and a printing method thereof. The laser printer includes an ink jet cartridge (3) filled with pigment ink, where a conveyor belt (6) is disposed below the ink jet cartridge (3), the semiconductor laser (4) is disposed on a side of the ink jet cartridge (3), and a photoelectric sensor (10) for detecting the position of an embedding cassette (1) is disposed on the conveyor belt (6). The beneficial effects brought by the printer and the printing method thereof are as follows: 1. By ejecting pigment ink droplets on an embedding cassette and irradiating the ink droplets with a laser beam from a semiconductor laser, the ink droplets have a rapid increase in temperature and are cured, so that colors are applied on a plastic surface and can be easily recognized. 2.
