Provide a means for Produce Packing house to easily print industry recommended track and trace bar codes on their cases.

The Produce Marketing Association has developed recommendations for case bar coding formats to support the produce packing house track and trace initiative. The components of the bar code are a manufacturer/product code and lot code embedded into a bar code that follows GTIN bar code recommendations. Currently most packing houses utilize either pre-printed cases with the product bar code pre-printed on the side of each case. Since the lot code is variable this solution will no longer work. The packing houses need to implement on-line case coding system. The two possible solutions are high resolution ink jet or a labeling system.
