Determining optimum print settings for new ink sets

Research and development

Every ink set has its unique physical properties. This necessitates finding the ideal machine settings for each case. A purpose-developed test rig provides very accurate simulation of a swissQprint printer.

One of its features is a "drop watcher" that we use to investigate droplet formation at the print head, which has a major influence on print quality. Only when droplet
