offset lithography
Offset printing is a common printing technique in which the inked image is transferred (or "offset") from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on ...
are planographic processes that rely on the property that water will not mix with oil. The image is created by applying a
