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 the repulsion of oil and water , the offset technique employs a flat ( planographic ) image carrier.
Before final printing, the image is proof printed and any errors corrected. In the direct form of printing, the inked image is transferred under pressure onto a sheet of paper using a flat-bed press. The offset indirect method uses a rubber-covered cylinder that transfers the image from the printing surface to the paper. Colours may be ...

Offset is a process similar to lithography, consisting of applying an ink on a metal plate, usually aluminum. It was the parallel product of two inventors: in 1875, the British Robert Barclay developed a version for printing on metals (tin) and, in 1903, the American Ira Washington Rubel adapted it for printing on paper.

The problem can occur with most types of printing, and is avoided by the use of slipsheets between copies (so any ink transfer occurs onto discardable paper) or anti-set-off spray powder. The term in offset printing also refers to the unwanted transfer of ink to rollers and friction points throughout the printing press. Ink that is not properly ...

Phototypesetting machines project characters onto film for offset printing. Prior to the advent of phototypesetting, mass-market typesetting typically employed hot metal typesetting – an improvement introduced in the late 19th century to the letterpress printing technique that offered greatly improved typesetting speed and efficiency compared to manual typesetting (where every sort had to be ...
