TubeScan – Smart 100% print inspection for maximum quality and efficiency

• Superb image quality due to high camera resolution 
• 100% web viewing during make-ready and production
• Detection of coarse to fine print defects, such as misprints, register defects and color deviations
• Detection of missing labels and matrix residues
• Surface inspection
• Counting of repeats and labels
• Placement control module with defect queue for automatic control of a rewinder
• Relative distance monitoring based on edges or shapes
• Delta-E monitoring

• Dynamic Roll Map for overview of production
• Defect Queue for placement control
• Roll report with defect images for documentation

• Intuitive Touch Screen with fast and easy job setup
• No health risk, less tiring compared to conventional strobe light monitoring
• Automatic repeat synchronization across the entire speed range of the machine
• Automatic label contour (die cutting) recognition
• Dynamic Job Change for inspecting multiple jobs on a roll without stopping the digital press
• Very reliable and stable operation

(1D- and 2D-barcodes, numbers, OCR)

• Inspection of print quality and content
• Dynamic verification, database comparison
• Export of results in CSV file for further processing

• Bright field illumination for highly reflective materials
• UV illumination for luminescent applications
• Contour light for recognition of elevations such as embossing, braille, clear-on-clear labels, clear-on-paper labels, matrix residue, wrinkles, bubbles
• Back light to reveal pin holes or internal structures e.g. RFID antennas
• Multiplexing combines several illumination modes in a single inspection run

• PDF Validation
• Import of prepress-defined inspection zones, such as masking, die-cutting contours, secondary inspection zones, static or variable 1D / 2D barcodes and alphanumeric sequences

Smart and economic automation and process integration

• Job Setup and Integration
  • Interfaces to prepress software and MIS / ERP systems
  • Referencing to databases
• QLink Press: On the printing press
  • Roll management
  • Real-time editor
  • Local or network storage
• QLink Rewinder: On the finishing machine
  • Control of the rewinder based on defect protocol
  • Camera-based synchronization and visualization
  • Optional 100% re-inspection
• QLink Editor: Quality management
  • Processing of all roll protocols in the network

• Video web viewing in addition to 100% inspection
  This patented combination with multiple cameras in one system provides a detailed zoom image with simultaneous 100% inspection. The TubeScan eagle view supports the complete range of hardware and software options offered with the TubeScan digital strobe.

Two camera units in one compact system allow simultaneous front and back inspection.
