2D Code Comparison:
Dot-Peen VS CMT Patented Square Dot
|
|
| |
|
A 2D code, or Data Matrix, is specifically designed to be read by a vision system. This machine readable code can be put on parts in a wide variety of methods. These methods include ink jet, dot-peen, scribe, and laser. Dot-Peen and Scribe provide the solutions with the deepest marks, are considered permanent, and economical as compared to other methods.

DOT-PEEN 2D Code
A 2D code, or Data Matrix, is specifically designed to be read by a vision system. This machine readable code can be put on parts in a wide variety of methods. These methods include ink jet, dot-peen, scribe, and laser. Dot-Peen and Scribe provide the solutions with the deepest marks, are considered permanent, and economical as compared to other methods.

|
|
|
Other 2D dot-peen marks can be subject to non-linear lines and missing marks. The I-Mark’s dual rail system maintains the precise lines required for the 2D code. In addition, the high torque stepper
|
|
|
motors and Kevlar reinforced belts, combined with an all metal pin assembly assure proper placement of each dot.
To check the quality of the mark, a 2D camera was used to read it. The camera has a variety of different filters and lighting methods. With these controls, the camera is able to read the mark 100% over 26 passes. While the conical
|
reflections vary, the depth of the mark is sufficient to provide solid readability across the entire mark.
The CMT I-Mark dot-peen solution may be passed over by some who have used other similar systems. However, this industrially designed dot-peen is well worth consideration

Square-Dot™ Scribed 2D Code
CMT is unique in offering the 2D as a scribe solution. This patented process provides a higher resolution mark. The scribed Square-Dot application draws each cell. While more time is required for this process, the diamond tip makes this a great solution for many applications.. The scribe mark shown was made with the CMT
|
|
|
|
I-Mark I series IMIS60. This diamond tip scribe uses ball screw drives to carve the tip through the material. The system has even larger motors than the dot-peen, and of course the all metal
|
|
|
housing assembly.
Again, the depth of the mark is extreme, compared to other similar methods. While the IMIS60 is used to make a 2D Square-Dot, the regular alpha/numeric characters are clearly defined.
Many customers have selected the scribe just for
|
the man-readable code applications. Of course, an added benefit is that this method is “silent” and does not make the percussion sounds of the dot-peen.
One of the methods the camera can employ is a darkfield. The darkfield allows this mark to be very clearly defined. The camera is able to read the mark 100% over 53 passes. The cells are boldly defined with the scribed squares.
The CMT I-Mark scribe solution may be passed over by some who have used dot-peen and have elected to upgrade to a laser. However, the CMT Square –Dot is both a more reliably readable solution than the Dot-Peen, and a more cost effective solution than a laser.
