Production flow insights

  • Printing plates are a key part in the offset process.
  • One plate is needed for each color unit
  • The average price being around 10 US dollars, a plate is by far the cheapest printing form
  • A plate is prepared according to the image file in around 1 minute via a CTP platesetter
  • Intelligent inking train (ink tank filling + ink film adjustment)
  • Easy and fast plate and blanket mount on cylinders (tightened or glued)
  • Instant 0 setting
  • Inker warm up and pre-inking in hidden time
  • High-end Komori PQC
  • Quick Color register
  • Pre-inking for reduced start-up waste
  • Safety device in case of web wrap-up around cylinders
  • Optional optical quality control (closed loop)
  • Most common technology is UV type, with intermediate color units dryers + a final dryer
  • Some markets exclude UV inks because of potential migration of ink photoinitiators. Therefore EB (Electron beam) curing can be selected
  • Flexo units can be added on the line either to apply varnishes or to print the inside box panels
  • Rotogravure units may be fitted in order to add metallic inks, holograms or large color patches
  • All designed and integrated by Komori-Chambon
  • Coatings, touch varnish, hot coil, cold foil…
  • Pre-setting of next job from CTP while the press is running
  • Automatic ink train washer
  • Fast plate change for new design / cylinder change if new layout
  • Cylinders shift without breaking the web
