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.
The paper passes between the blanket cylinder and a counter-pressure or impression cylinder and the image is transferred to the paper. Because the image is first transferred, or offset to the rubber blanket cylinder, this reproduction method is known as offset lithography or offset printing. [13]
Lithography and offset lithography are planographic processes that rely on the property that water will not mix with oil. The image is created by applying a tusche (greasy substance) to a plate or stone. The term lithography comes from litho, for stone, and -graph to draw. Certain parts of the semi-absorbent surface being printed on can be made ...

Chromolithography is a method for making multi-colour prints. This type of colour printing stemmed from the process of lithography, [1] and includes all types of lithography that are printed in colour. [citation needed] When chromolithography is used to reproduce photographs, the term photochrome is frequently used.
In offset lithography, the image is chemically applied to a plate, generally through exposure of photosensitive layers on the plate material. Lithography is based on the fact that water and oil do not mix, which enables the planographic process to work.
The most commonly used graphic methods were woodcut, lithography, etching and silkscreen printing, and new techniques such as color aquatint were developed. [2] The offset printing also emerged, which revolutionized graphic art. Offset is a process similar to lithography, consisting of applying an ink on a metal plate, usually aluminum.
Rachel Robinson Elmer, halftone offset lithograph, Woolworth Building June Night, 1916, The National Gallery of Art, Washington, D.C. Photo-lithography captures an image by photographic processes on metal plates; printing is more or less carried out in the same way as stone lithography.
