Paper Bag Coding

Definition of Task

paper bags filled with cement and caulking compound are coded from both sides at a print-height of 25 mm (1 inch)

print information: product code, product number and an EAN 13 barcode
the filled bags pass by the two print heads positioned on the opposite sides of a conveyor belt with a speed of 40 m/min. (130 feet/min.)
immediately after the printing process the barcodes are scanned and checked on either side of the bag. If both barcodes are not readable, the conveyor is stopped and a label printer which is connected to the controller puts a label on the bag
printing takes place in a very dusty environment
temperatures vary according to the change of season and between – 4° and +40° Celsius (+25° and +104° Fahrenheit)

easy operation since the text selection and assignment is done by means of a text selection box
robust and reliable printing system which provides high quality print results even under dusty environmental conditions
very well legibility of the text and high barcode reading rates
