Many important operations in a business such as maintaining flow of information intra-company and marketing the offerings of the company need printing service. Therefore, it is good to have some basic knowledge of how printing works, especially offset printing, which is one of the most widely employed printing techniques.

The users and the printers like offset printing because of its cost effectiveness for printing of large number of prints. Hence for bulk orders any good printing company would recommend you to go for offset printing.

This printing technology uses oil-based ink, which the water can not dissolve. The offset printing gets its name from the fact that the designs are transferred indirectly from the plates to the paper by use of rubber blankets as the medium.

First step is to develop the images. When offset printing started, the images had to be developed by the use of film negatives and they were later put on aluminum plates. However, a modern printing company would now prepare the plates directly by using an image setting system. This plate is then placed on a cylinder with the correct side up. Next, the water is put on the image plates, which is followed by the ink. The image gets the ink while the rest of the area gets a thin layer of water, which makes sure that the ink does not spread beyond the images.

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 inverted. The image is now printed with its right side facing up by cutting sheets of papers into appropriate size and placing them on a third cylinder.

The task of printing is finished 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 requirements of the client.
