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 Process
This printing method makes use of positively charged inks/toners that get attracted to negatively charged paper coated with a layer of zinc oxide. thereafter the paper is moved through an ink bath tub, where the positively charged articles of ink stick on to the negatively charged paper.
