Abstract
This paper explains technology of Elcography which is a brand-new method of digital printing. The technology gives printed images by electro-coagulation. The volume of ink coagulation varies with time of chemical reaction between polymers and ferrous ions. Each dot can have different thicknesses. The digital image can be kept in continuous-tone mode without need of complex and time-consuming half-tone screening algorithms. The electro-coagulation reaction is very fast. The ink reacts to electricity in 4 microseconds. At a resolution of 400 dpi, the normal printing speed is 400 ft/min for 15 inch-width web.
