Board card voltage on applicator practical work in print, life has a very important impact. As the voltage level of the printer head can decide the sheet inside the printhead of Piezoelectric ceramic bending and, therefore, high voltage can increase the amount of ink-jet nozzle, without affecting the lower printed under the picture quality is better.By the relevant institutions proved that exceeds 32V voltage may cause the sprinkler off Mo ridden and loss of life occurs.Said will bend the Piezoelectric ceramic high voltage was increased, if in a State of high frequency oscillation, and piezoelectric Crystal inside the nozzle easily tired and injury break, and the sprinkler voltage too low will have impacts on the saturation of the picture. so the sprinkler between the 28V-32V voltage is suitable.Different brands of printer applicators voltage varies, such as Epson nozzle voltage 30V, cyber nozzle 33V voltage, voltage of 38V precision printhead, printhead on the viscosity of ink and different voltage requirements vary, spray Ink viscosity also high voltage requirements, low viscosity of the ink printhead of low voltage requirements, which are proportional to.
A. printhead high voltage and low viscosity of the ink, it will cause the ink too much, too soon, dot reflex to the bottom of the printhead to form droplets clogging printhead, there will be rough edges and there was ink.
B. low voltage and high viscosity of the ink, if printhead, there will be sprayed out ink, color is not uniform, not full, and so on.
In addition, dry fast and slow drying of the ink! Quick-drying ink is UV light exposure may also result when ink is not the material has dried up, thus leading to printhead clogging!
