Core77

The Roland Metaza printer with "Photo Impact Technology" prints halftone images on reflective surfaces in a way that you wouldn't expect. Rather than adding ink or coloring, the machine uses a diamond-tipped stylus to engrave dents of varying size into the surface of the print media. The size of the dent corresponds to the value of the pixel, which creates a composite image of thousands of dents. The printer can print on anodized aluminum, brass, steel, copper, acrylic, and a variety of other materials, and it can even handle surfaces which are less than perfectly smooth.
