Digital printing is getting closer to offset printing, with each of these technologies having its reason. Offset printing is one of the oldest printing technologies. This is indirect printing, as the resultant image is first printed from a printing mold (flat or cylindrical) to a rubber cylinder and then to the paper. It is a wet printing process using printing ink, that is transferred from the mold to the printed material on the basis of the different physico-chemical properties of the printing and non-printing locations.
