Electrostatic Printing Process

Electrostatic Printing: Electrostatic printing technique is a type of printing done without the use of a plate, or ink or a type form. Paper is coated with an extremely thin layer of zinc oxide. This makes it an it an insulator in the dark while at the same time a conductor of electricity when it is exposed to light.

Electrostatic Printing machines are generally used for the printing of geographic maps. as the technology advances and speed increases these machines are being used to print smaller books as well. Electrostatic printers can be used for short run printing projects because they are faster than many alternatives and also do not cost a lot.

Electrostatic Printing Process
This electrostatic printing technique uses positively charged ink or toner that get attracted to negatively charged paper that has been coated with a very thin layer of zinc oxide. Afterward, the paper is moved into and through an ink “bath tub”. In the ink bathtub, the positively-charged bits of ink stick to the negatively charged paper.
