Square-Dot® Process
US Patent No. 7,191,529
CMT's patented high resolution marking process to apply 2D/UID machine readable codes to a variety of materials. This process scribes a matrix of small square cells into the material. The mark provides the best direct part reading with a vision system as the cells are filled in similar to a laser mark but much deeper and often with better contrast.
The Square-Dot® process may be implemented by using either Signumeric 2D software or an Industrial PC, preloaded with Signumeric 2D software.

The Square-Dot® patented process uses a diamond tip to draw squares on material to create a machine readable 2D/UID code. This technique creates both a depressed square and a raised ridge as shown below. The “filled cell” reflections create a more defined matrix as shown above, and therefore, offers better readability.
