Printing plates are thin, flat sheets of metal commonly made from aluminum. The full name of the offset printing process is offset lithography. In another type, the photoconductor is a coating on the substrate itself, the toned image being formed directly on the substrate. The ink penetration is promoted by pressure between the printing plate and the paper substrate. Request a benchmark plate Don’t take our word for granted. The metal printing plate is then heated, meting the resin which forms tiny particles as it hardens and cools. In some cases the plate was formed as a cylinder for high-speed printing Text is made up of movable type.
