This text was marked using a Synrad 25W laser, FH marking head and a 200mm flat field lens providing a 290 micron spot size with 5mm depth of focus. The inked layer was easily ablated using 18W at a speed of 45”/s, giving a mark cycle time of 0.3s.  Using Synrad's WinMark Pro software users can easily change lot numbers and expiration dates. In addition to text, the software has a large library of codes including UPC, EAN, 128, 3 of 9, Code Bar, PDF 417, Postal Code, Data Matrix, and QR codes.

Laser ablating an inked layer on boxes is a popular method of marking date codes in the packaging industry.
