Marking and coding of 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.
