Square-Dot®
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.

Square-Dot® UID/2D

All the rest (dot-peen)
The Square-Dot® process may be implemented with any of CMT’S I-Mark Scribe systems,
these include I-Series air Scribe & the C-Series electric or air scribe.
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.
