OFFSET PRINTING
The lithography technique developed in 1904 by Ira Rabuel of the USA was first developed. With the development of the printing industry and technology, it is the standard commercial printing methods most commonly used by businesses and organizations in the 20th century. It is a widely used printing technique in which the offset printing ink image is transferred to the printing surface first and then to a rubber cover. It is based on the principle that water and ink do not mix.

Image information (picture and text) is printed on thin metal plates by the cylinders with water and ink. There are areas to be printed and not printed on the mold surface. The areas to be printed are kept in water and the areas that are not to be printed with ink. The oil-based ink image (area to be printed) and the non-image area (non-printing area) are met with a mixture of water and alcohol. The basic operating principle of offset printing is based on the principle that these two areas on the mold are separated from each other.
