Why DPM Scanning Is Hard
Direct Part Marking (DPM) codes are laser-etched, dot-peened, or chemically etched directly onto metal, plastic, and glass surfaces. Unlike paper labels, DPM codes have low contrast, high reflectivity, and tiny sizes (sometimes just 2mm).
Standard barcode scanners fail on DPM. You need specialized industrial readers designed for these challenging marks.
