Direct Part Marking (DPM) is a process that allows users to imprint a bar code directly on an item instead of printing the code on a
paper label. Different technologies are available to directly mark objects: laser/chemical etching, dot peening and ink jet printing.
Each of these methods have specific advantages and disadvantages in terms of durability, cost and ease of reading.
The PowerScan series of scanners are rugged handheld area imagers specifically addressed and capable of reading codes marked with DPM.
