Offset printing is the most frequently used printing technology and learning about it is therefore helpful and important. The customers and the printers like offset printing because of its cost effectiveness for printing of large number of prints. The customers giving bulk printing orders are advised by the printers to opt for offset printing because of this reason. The ink used during offset printing has oil as the medium and is insoluble in water. The offset printing gets its name from the fact that the designs are transmitted indirectly from the plates to the paper by use of rubber blankets as the agents. The first step is developing the images. Film negatives were used in the earlier times for making images and then duplicating them to aluminum based printing plates. However, a modern printing company would now prepare the plates directly by making use of an image setting system. This plate is then put on a cylinder in the proper configuration. Water and ink, in that order, is spread on the image plates. While the ink gets fixed to the image, the water gets attached to that part of the plate which has no image so that the ink does not spread beyond the image. Next, the image is turned around when it is put on to a rubber blanket which is attached to another cylinder. The image is then printed with its correct side looking up by cutting sheets of papers into appropriate size and putting them on a third cylinder. Last steps of the printing job involve things such as stapling, pasting or arranging the printed sheets according to the instructions of the client, and any printing company should easily manage these.
