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.
