The substrate may be metal or plastic. A process is described for forming a plurality of two dimensional matrix symbols at the same time in batches. The two dimensional data matrix symbol includes a substrate, a plurality of grooves and a plurality of raised areas, and a plurality of ink spots disposed in the grooves according to a predefined code. The matrix is readable by a scanning device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Chemical etched two dimensional matrix symbols and method and process for making same","description":"A chemically etched two dimensional matrix symbol is provided on a substrate.
