Marking and coding of glass

  • Glass

Glass is not absorbent, usually has a smooth surface and is frequently processed in a curved form. Industrial inkjet printers from LEIBINGER master these challenges posed by glass and provide permanent and efficient glass marking and coding. The non-contact printout allows products to be applied on the fly and/or in wet or dusty production environments. In addition, LEIBINGER camera systems meet the highest demands of verification requirements. The LKS 5 reads and checks both fixed and variable data, text segments and barcodes.

Typical markings

  • CE marking
  • Expiration dates
  • Barcodes
  • Characters and text
  • 2D codes, e.g. QR codes, DataMatrix codes, etc.
  • Batch numbers/lot numbers
  • Company logos
  • Lottery codes/numbers

Materials

  • Glass bottles/glass parts
  • Glassware made from silicon dioxide/acrylic glass/Plexiglas
  • Metallic glassware (amorphous metals)
  • Window glassware (incl. spacers)
  • Beverage and food glassware (beverages, bottles, jars, etc.)/packaging glasses
  • Non-returnable bottles
  • Returnable bottles/recyclable bottles
  • Clear glass/brown glass/green glass
  • Technical glasses (test tubes, Petri dishes, etc.)
  • Solar panels/photovoltaic systems

Examples of typical applications

  • Removable marking for returnable bottles/recyclable bottles (alkaline solution)
  • Traceability/track and trace/identification
  • Very high durability for the inks used
  • Print with light contrast inks on dark backgrounds
  • Use of (soft) pigmented inks (opaque inks), such as for marking brown or green beer bottles
  • Use of UV-resistant inks when marking
  • Use of FDA-compliant inks
  • Marking in wet production environments

Typical print monitoring tasks

  • Print monitoring/verification/image processing of various printouts
  • Monitoring the presence of items, such as dispensed products (cards or samples)
  • Reliable monitoring of inkjet fonts (printouts of small character inkjet printers)
