Offset printing employs oil based ink, which does not mix with water. Its so called because in this process, images are not transferred directly from the plates to the paper but this is done using rubber blankets as a medium.

The process starts by developing the designs. Film negatives were used in the past for making images and then copying them to aluminum based printing plates. In the current times, the printers can use the image setting system for preparing the plates directly. This plate is then put on a cylinder with the correct side up. Water and ink, in that order, is spread on the image plates. The ink is spread over the image and to restrict it from overflowing, a thin layer of water is put over the remaining part of the plate.

After being painted with the ink, the image is kept on a rubber blanket which is on a different cylinder, resulting in the image to be inversed. The image is reversed to its right side by transferring the image to sheets that have been cut in line with the need and are placed on a different cylinder.

The work of printing is completed by the printing company by providing the final touches to the printed sheets using staples or paste or in any other way as per the needs of the client.
