LithoSpectral Web

LithoSpectral Web enables the spectral measurement and color control of printed products especially in web offset printing. Measurement is performed in print control strips or at appropriate positions in the printed image, and the system can achieve considerable savings in a short time.

Customer Benefits:
  • High savings thanks to LithoDyn dynamic control
  • Minimal energy costs thanks to LED lighting
  • Clearly structured user-friendly interface
  • Definable print control strips
  • Long service life and low operating costs
  • Can be adapted to various printing machines
Application Areas:
  • Measurement and control of Lab values and the densities of process inks and special colors
  • For web offset printing machines with a production width of 52-205 cm
  • Monitoring of tone value increase, print contrast, trapping, delta-E and contamination parameters
  • Compact complete system for new and used printing machines
