swissQprint flatbeds with vacuum innovation

The swissQprint flatbed printers now come equipped with a new vacuum table that is subdivided into 256 segments. The user can switch segments on or off quickly, easily and steplessly at the touch of a finger thanks to the swissQprint Tip Switch Vacuum (patent pending). This eliminates tedious and time-consuming masking and taping, not least in the gap between boards and dual rolls. Because there is no air leakage, the vacuum develops its full force and reliably holds down even unruly media such as corrugated board. The vacuum table also incorporates a cutting channel that provides a defined and precise trimming edge for roll materials and thin media.

For tandem production, the vacuum table is divided into two zones, each independently adjustable by the Tip Switch Vacuum. Tandem enables non-stop production: media are loaded onto the printing table alternately at the front and rear. While printing is underway on one side, the operator loads the other side, and vice versa – without idle time, until the series is complete.

Via the output software, the user regulates the vacuum strength and is also able to reverse the thrust, meaning that the pumps blow instead of sucking. This creates an air cushion on the print bed that eases the handling of heavy boards. They can thus be positioned or moved with little effort and without risk of material damage.

The vacuum pumps are underpressure controlled, so they automatically reduce speed once the required negative pressure has developed. This contributes to the system's overall low power consumption: swissQprint large format printers have been ISO 20690:2018 certified for their high energy efficiency. Besides this, thanks to underpressure control, the vacuum is pleasantly quiet.

All swissQprint flatbed models – Oryx, Impala and Nyala – are now shipping with the new vacuum system. The swissQprint Karibu roll to roll printer has featured the Tip Switch Vacuum since its introduction last year. And this has proven itself, with users praising it as an "ingenious feature".
