Direct Part Marking (DPM)

Microscan Leads Direct Part Mark Reading Technology

Direct part marks are typically 2D Data Matrix symbols permanently marked by methods such as dot peen or laser/chemical etch onto substrates including metal, plastic, rubber or glass. These marking methods often result in low contrast visibility of the symbol or inconsistent imprints that can be challenging to decode through traditional imaging technology.


Microscan has the broadest product line available for specialty imagers and verifiers focused on solving challenging DPM applications. Our Hawk DPM Series leverages combined technologies of patented machine vision illumination and aggressive X-Mode Direct Part Marking algorithms to provide the robust performance to easily read any 2D or barcode symbol including challenging direct part marks.
