Offset printing is an indirect print technology where the print color is first transferred from a mostly thin, flexible aluminum plate to a rubber cylinder and then to the material to be printed. The four colors cyan, magenta, yellow and black are printed one after the other and finally produce a high-precision color picture. Commercial web offset
