Now a days use of offset printing is increasing day by day . One of the important functions in the printing process is prepress  production. This stage makes sure that all files are correctly processed in preparation for printing. This includes converting to the proper CMYK color model , finalizing the files, and creating plates for each color of the job to be run on the press.
Offset printing is a commonly used printing technique in which the inked image is transferred (or "offset") from a plate to a rubber blanket, then to the printing surface. When used in combination with the lithographics  process, which is based on the repulsion of oil and water, the offset technique employs a flat ( plainographic ) image carrier on which the image to be printed obtains ink from ink rollers, while the non-printing area attracts a water-based film (called "fountain solution"), keeping the non-printing areas ink-free. The modern "web" process feeds a large reel of paper through a large press machine in several parts, typically for several metres, which then prints continuously as the paper is fed through.

Advantages of offset printing compared to other printing methods include:
·         consistent high image quality.  Offset printing produces sharp and clean images and type more easily than, for example, letterpress printing ; this is because the rubber blanket conforms to the texture of the printing surface;
·         quick and easy production of printing plates;
·         longer printing plate life than on direct litho presses because there is no direct contact between the plate and the printing surface. Properly developed plates used with optimized inks and fountain solution may achieve run lengths of more than a million impressions;
·         cost. Offset printing is the cheapest method for producing high quality prints in commercial printing quantities;
·         ability to adjust the amount of ink on the fountain roller with screw keys. Most commonly, a metal blade controls the amount of ink transferred from the ink trough to the fountain roller. By adjusting the screws, the operator alters the gap between the blade and the fountain roller, increasing or decreasing the amount of ink applied to the roller in certain areas. This consequently modifies the density of the colour in the respective area of the image. On older machines one adjusts the screws manually, but on modern machines the screw keys are operated electronically by the printer controlling the machine, enabling a much more precise result
