Square-Dot® Patented Process & Direct Part Marking DPM of 2D Code

Square-Dot® is 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.

CMT offers a wide range of Direct Part Marking products. Often referred to as:

  • 2D Barcode
  • Square-Dot
  • 2D Code
  • Data Matrix
  • UID

DPM Direct Part Marking: UID/2D Matrix is a barcode system that allows for direct part marking into the material of a component or part. This machine readable code is "read" with a camera. Direct Part Marking is an intregal part of any automated production tracking process.
Terms & Definitions:Commonly used words and descriptions for the 2D Code applications and marking process. Terms include Direct Part Marking, Structured light, and quiet zone.
Link to 2D code page 2D Code: 2D Code explained what each element is and what it should look like.
Link to Factors to be Considered page Factors to be Considered: 2D Code applications have many components to be evaluated to make the right choice for the proper marking machines and vision systems.
Link to 2D code benefits page Benefits: 2D Code Direct Part Marking applications have some very rewarding results for manufacturing.
Link to DOD UID Marking Page DOD UID Marking:The DOD has new requirments for part tracking. CMT's 2D code marking machines are DOD compliant. l
Link to Encryption Page Encryption:The number of character encrypted in the 2D code and the resulting number of columns and rows required.
Link to 2D Code Size page 2D Code Size:The size of 2D is based on two factors the number of columns and rows and the cell size. The resoution of the cell size is based on the material and the process makring the 2D code.
