Issue: Direct Part Marks (DPM) are codes, symbols, and texts that are etched or printed directly onto the surface of a part, which has a different texture from marks printed on paper. They are often inverted on a dark surface.
Solution:
Enable the DPM reading mode and invert the color of the image using GrayscaleTransformationModes.
