Solenoid valve printing

Solenoid valve printing is a digital non-contact printing technology. The ink reservoir is pressurized with an overpressure of several bar and the drop is triggered by a fast electromechanical opening and closing of a solenoid valve, whereby the drop is ejected from the printing nozzle. Compared to inkjet printing, this technology allows the application of larger droplet volumes and working in a wider viscosity range, while featuring greater minimum line width and lower possible printing frequency.”
