Printing service is used by most organizations for varied functions such as marketing and intra-company communications. Therefore it is helpful to learn about the basic working of the frequently used printing process called offset printing.

Offset printing is so popular among printing service companies and clients because for large quantities, it turns out to be cheaper than alternative methods. Hence for bulk orders any good printing company would recommend you to opt for offset printing.

The ink used during offset printing has oil as the medium and does not dissolve in water. Its name comes from the fact that in this method, images are not transferred directly from the plates to the paper but this is done using rubber blankets as a medium.

First step is to develop the graphics. Film negatives were employed in the earlier times for making images and then copying them to aluminum based printing plates. In the present times, the printers can make use of the image setting system for making the plates directly. The subsequent step is to attach the plate on to a cylinder such that it is spot on. Then the water and ink are dispersed on the image plates, one after another. The ink is poured over the image and to prevent it from spilling, a thin layer of water is put over the remaining part of the plate.

After being painted with the ink, the image is put on a rubber blanket which is on a different cylinder, leading the image to be reversed. The image is now printed with its right side facing up by cutting sheets of papers into appropriate size and putting them on a third cylinder.

The final steps of the printing job involve things such as stapling, gluing or arranging the printed sheets in line with the instructions of the client, and any printing company should easily manage these.
