INTEGRA PP108 is a monocolor print system intended for large print areas on corrugate and other porous substrates. The system prevents the accumulation of air in the nozzles and ensures a permanent, clean print image without line-outs due to dropping nozzles. Pump control and automatic adjustment of internal circulation pressure allows installation of the ink tank above, below or same level as the print head. The air in the ink supply and print head is automatically removed from the print system.
