What the company calls “the world’s largest flatbed printer” was installed recently at sedak GmbH & Co. KG’s Gersthofen, Germany location. With the addition, the company now offers digital ceramic-ink screen printing technology for oversize glass formats.
“Excellent quality is not all we get with a print resolution of 720 dpi. In digital printing the ink can also be applied in much thinner layers than is the case with screen or rotary printing,” says Bernhard Veh, sedak’s managing director. “This technique allows us to achieve translucent printing and graduated transitions.”
According to the company, the printing process is similar to that used by ink-jet printers for paper. However, the inks consist of ultra-fine ceramic particles. These ceramic inks are sprayed onto the glass surface with a plotter. Subsequent firing in a furnace bonds the inks permanently to the glass. The fired ink coating is durable and scratch-resistant. After printing, the glass can be laminated, cold-bent or processed to create insulating glass units.
