Definition of Task

• Ceramic particle filters for the automotive industry are coded with a CO2-Laser while resting in two parallel operating machines

Special Product Specification

• The code consists of four arrows indicating the flow direction and a datamatrix code
• The datamatrix code consists of an automated date field and a six digit counter
• The date is encoded by the julian day and two digits indicating the year
• The counter is initialized each day
• Since the ceramic material reacts by showing a black color change, the datamatrix code is printed as positive
• Next to the datamatrix code its content is printed as a readable alphanumerical code
