droptical GmbH - Inline, full-printhead camera inspection for inkjet

Inkjet printing nowadays has a lot of different tools for inspection of the print process. However dropwatching, which provides the most information, is mainly used for waveform optimization in the laboratory setup so far and, less commonly, as a separate checking station in a plant. This talk will sketch the current development of droptical systems to provide an inline camera inspection solution covering all nozzles of a printhead simultaneously. This ensures consistent print quality and offers a significant advantage when changing to new batches of ink. Especially in modern applications that use higher viscosity inkjet printing, this can provide huge benefits regarding process stability and early scrap detection. In addition, an inline camera offers the possibility of closed loop control.
