SwissQprint’s patent-pending Tip Switch Vacuum operates selectively and powerfully to boost everyday efficiency. All swissQprint larg- format flatbed printers now come with this new system. The new vacuum table has been subdivided into as many as 256 segments. Users can switch segments on or off quickly, easily and ‘steplessly’ at the touch of a button. This eliminates tedious and time-consuming masking and taping, especailly in the gap between boards and dual rolls. Because there’s 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.
Two zones for tandem production. 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.
Reverse thrust for air cushioning. 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.
Energy efficient. The vacuum pumps are pressure 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 and operate quietly. 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.
