Application areas

  • For sheet-fed and web offset printing machines with a production width of 52-205 cm
  • Measurement and control of the densities of process inks and special colors
  • Monitoring of tone value increase, print contrast and trapping parameters

Customer benefits

  • High savings thanks to LithoDyn dynamic control
  • Minimal energy costs due to flashing LED
  • Clearly structured user-friendly interface
  • Definable print control strips
  • Effective protection against contamination thanks to innovative glass/visor system
  • Long service life and low operating costs
  • Can be adapted to various printing machines

Checking station for job identification based on image content

LithoJobident enables permanent job identification and marking based on image information. Incorrect processing steps or deliveries can thus be effectively prevented.

Application areas

  • Print shops
  • Print further finishing process

Customer benefit

  • Prevention of incorrect deliveries
  • Prevention of incorrect further processing steps
  • Permanent assignment without barcodes or job numbers

Optimum CMYK and special color ink key presetting for all printing machines.
Also available as a standalone with touch display.

LithoCIP allows offset printing machines to integrate ink key presetting. Based on digital job data CIP3, PDF and TIFF file system, LithoCIP identifies optimum ink presetting values for all printing units.

Application areas

  • Supported by various types of printing machines and manufacturers
  • Offset printing sheets / roll
  • Metal printing

Customer benefits

  • Fast setup process with optimised presetting values
  • More accurate control and fast response times thanks to balancing
  • Preset curves for process inks on different substrates available

LithoDyn - Due to the slow adjustment processes, each offset inking unit needs many sheets to convert setting steps into hue changes.

Scope of application

  • Retrofit equipment for print shops with the wish to save make ready and printing costs
  • Optional for Densitronic Professional / Basic, LithoScan Professional / Basic

Customer benefits

  • Significant time reduction of pre-setting and control procedures
  • Up to 50% less waste due to faster make ready
