Automated Image Quality Control on Weboffset Presses without any need for Special Strips and/or Patterns

Underneath described inline fullcolour printcolour measurement and control system is invented to control and adjust inline the print quality on weboffset presses, without needing any printed colour bars, -patterns or strips. Specifically applicable in situations of fullcolour printed news-papers, untrimmed retail print and application of narrow gap presses. This Dutch invented system measures the real printed images and adjusts the printed colour accordingly. Gains for printers are less human eye-, but more system controlled colour quality maintenance. A two way use of the system is possible: either the system controls and guides the web printing press to the right colour based upon the ripped document, or guides the print production based upon the print sample signed for 'okay' to print the order.
