Completed installation of our own custom print reinsert registration system as an upgrade repair to an older press.
The result was increased registration accuracy, higher speeds and reduced setup waste.
Ripped out the old ailing dc drive and motor, replaced with AC servo, high speed PAC plc, HMI and optical registration sensor. The system detects print marks on a preprinted unwind roll and adjusts the infeed position to align the incoming print to the master print cylinder: this gives a four colour press another registered pass making it effectively 8 colours. When not registering the new system just regulates the infeed tension.
