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™ 9500-DPM Evo series of scanners are rugged handheld area imagers
specifically addressed and capable of reading codes marked with DPM.
