2D Code Marking Method Comparison

What follows is a comparison of three different marking methods for 2D code.
#1 Dot-Peen
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.
#2 Scribe Patented Square-Dot
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.
#3 Laser
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.
