METAZA Mechanical Operation

How METAZA marks dots on metal

METAZA impacts a conical diamond-tipped stylus onto a metallic surface to make a depression. The areas with depressions look lighter than where there are none. These differences form an image. (A depression = a dot.)

How METAZA creates tone

METAZA changes the size of a dot to create the tone of an image. (The stronger the impact, the larger and deeper the depression will be.) METAZA varies the impact with a diamond tip so that the image consists of smaller dots for darker areas and larger dots for brighter areas. METAZA driver automatically controls the size of the impact. You can also change the size by adjusting the settings as you wish.

Each dot in the image below was impacted with the diamond-tipped stylus. You can see larger dots in brighter areas and smaller dots in the darker area.

(The black area with no dot is the surface color of the metal reflecting darker.
