2D Code Marking Method Comparison

What follows is a comparison of three different marking methods for 2D code.

Dot-Peen is a “low resolution marking method. A single dot defines each cell. The grade of the mark is determined by the quality of the filled cells. Poorly filled cells result in poorly read marks.

Square-Dot is a patented process by CMT. Each cell is scribed. The scribed squares fill the cell and result in a higher resolution mark and better reading and verification by cameras.

The highest resolution Direct Part Marking method is laser. The fine precision of the laser marking allows for the smallest cell size and the smallest possible 2D code size.
