Offset lithography uses the basic principle that oil and water don't mix to produce a printed image.
First a specially coated plated is exposed to a negative of the image to be printed. Once it's developed, the plate will repel water in the areas where ink is desired, and attract it in the non-image areas.
On press, the plate first runs past a roller with a thin film of water on it. The non-image areas pick up a tiny amount of the water.
Then it passes a roller with a thin film of oil-based ink on it. The damp areas of the plate repel the ink, while the image areas pick up a thin coating of it.
The inked areas are transferred to a "blanket", a rubbery sheet of material that picks up the inked image. The blanket is then pressed against the paper, and the ink transfers to the paper, producing a printed image.
