Virtuoso Print Quality System

Presstek's (Booth 3117) Virtuoso is an inline print quality system for the Presstek 75DI digital offset press. Virtuoso performs a complete inspection of each sheet in real time preventing inadvertent delivery of defective sheets to the customer. Advanced reporting and data collection supports process improvement. The result is reduced operating cost and a more stable print run.

Virtuoso consists of four modules.

  • Color Management: Virtuoso’s Compact Imaging Sensor (VCIS), integrated into the last unit of the press, reads the color bar on each sheet and makes any necessary adjustments to ink density on the fly.
  • Defect Detection: Virtuoso checks each sheet for print defects including hickeys, marking, scumming, substrate defects, color variations, register defects, inking issues and scratching. Sheets with defects are automatically marked as they are delivered to the stacker.
  • Registration Control: Virtuoso scans the registration marks on each sheet produced by the Presstek 75DI, automatically initiating any needed adjustments during the production run.
  • PROOF+ Defect Detection: Each sheet is also scanned and compared to an approved PDF master for detection of any plate imaging or production errors.
