WARRENDALE, PA—AIM Global announced that the second Public Review Draft of the AIM Global Direct Part Marking (DPM) Quality Guideline, developed by a joint ad hoc committee of members of ANSI MH10 SBC 8 and AIM Global's Technical Symbology Committee (TSC), is now available for a 60-day public review. DPM is a technology where an item is altered physically by methods such as dot peening, laser etching, molding, and embossing to produce two different surface conditions. As a result, there is often very little or no contrast between the "marked" elements of a symbol and the background (substrate). Contrast can be achieved by using specific types of lighting and signal processing techniques.
