Ricoh head is produced in Japan, is currently the most cost-effective printing industry in a nozzle, now the market is the most used Ricoh G5 head. It has fast printing speed, high printing precision, variable droplet technology grayscale printing can make the printing process easier and more stable. Grayscale printing refers to the function of spraying droplets of different sizes (volume, diameter) in the same nozzle (orifice) according to different requirements. It is in the same jet hole, by controlling the vibration of the piezoelectric body, in a very short period of time in succession ejected one or more small ink droplets, small ink droplets before leaving the nozzle by several small ink droplets into a large droplet, so that the picture to achieve the HD beautiful effect.
RICOH Gen5 head: the Gen5 head is a fully closed sprinkler head with double row into the ink tube, fine ink dot, grayscale printing, waterproof and anti-aging. The nozzle has a built-in thermostatic system, and the printing voltage can be adjusted with the temperature to achieve a more stable printing state. The electric circuit board of the sprinkler head is fully covered by metal, which can soak ink without damaging the sprinkler head. The sprinkler head has a long service life and can be used normally for 3-4 years. It is the most successful type of piezoelectric sprinkler head.
Seiko 1020 head: Seiko SPT1020 head is produced by the Seiko electronics group. The circuit board of its sprinkler head is bare, easy to be stained with dust ink, a serious word still can cause sprinkler head circuit short circuit burns sprinkler head. Print low PASS output color is weak, the green yin-yang channel is obvious (control board and RIP software design problem). Nozzle life is not long, one year after the use of nozzle plug serious.
Seiko head for all steel structure, the current basic for SPT1020 35 pl nozzle on the market, because of the nozzle aperture is too large, the precision of the nozzle is quite rough, live simply is to do fine, drops technology is fixed, the service life of 1.5 years to 2 years or so, the price 10000 RMB, compared with the Ricoh head completely no advantage. In general, Ricoh G5’s head design is more reasonable, the printing effect is more fine, with variable ink drop technology, longer service life, from all aspects of grinding Seiko head.
