  • Sheet position control in die cutters
  • Imprint electronic register control
  • Detection of the smallest geometric errors

Customer benefits

  • Prevention of mixed typefaces and turned sheets
  • Outward transfer or removal of faulty sheets
  • Automatic saving of log files
  • Input display in motif selection
  • Less additional space and maintenance requirements
