Electrostatic printing is
a printing technique done without any plate, ink or type form.
The paper is coated with a thin layer of zinc oxide, making
it an insulator in the dark and simultaneously a conductor
of electricity when exposed to light.
These machines are used
for printing of geographic maps. With the advancement in technology
and higher speed, the machines are also being used to print
small books. Electrostatic printers are used for short run
printing as they are faster and also do not cost much.
Electrostatic printing use a positively charged toner/inks
that is attracted to paper which in turn is negatively charged.
The paper is moved through a digital ink bath; positively
charged particles in ink stick to the negative charge on the
paper. The printers print in black and white or color as the
case may be, and some handle paper up to six feet wide.
Application of Electrostatic Printing: Electrostatic printers are widely used
in different industries for short run printing. They are popular
for photocopying jobs both black & white and colored.
