Electrostatic Process: Reproduction method in which
image formation depends on electrical, rather than chemical
changes induced by light. Xerography is becoming a
generic term for the electrostatic copying/duplicating process.
Matte: In reproduction, a relatively rough, low-gloss surface particularly
suited to drafting in either pencil or ink.
Overlay: Transparent or translucent prints which, when
placed one on the other, form a composite picture.
Pin Graphics: A reprographic system using pin bars to obtain efficient
and precise registration of a series of overlays to produce a composite.
Polyester Film: A type of film with high strength and dimensional
stability used as a base stock for light sensitive coatings and drafting
Reproducible: Capable of producing copies in diazo or
Reprography: The art and science of reproducing
Right Reading: A copy which is readable from the front or
image side of the material.
Transparent: Material through which light can pass and which
can be seen through distinctly.
Transparentizing: Use of oil, waxes or other material to make the
base of an intermediate more translucent and thus increase its printing speed.
Vellum: Translucent paper for original drawings and certain sensitized products.
