Printing service is used by most organizations for different purposes such as marketing and corporate communications. Hence, it is good to have some basic knowledge of how printing works, especially offset printing, which is one of the most widely used printing techniques.
Offset printing is so well known among printing service companies and clients because for large volumes, it is more economical than other options. The clients giving big printing orders are advised by the printers to opt for offset printing due to this reason.
This printing technique uses oil-based ink, which is not soluble in water. In offset printing, rubber blankets act as intermediate for copying the image on the paper, which is originally on the plate.
The first step is preparing the images. Film negatives were employed in the earlier times for making images and then copying them to aluminum based printing plates. But, a modern printing company would now prepare the plates directly by making use of an image setting system. The next step is to attach the plate on to a cylinder such that it is spot on. Next, the water is spread on the image plates, which is followed by the ink. 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 spill beyond the image.
Next, the image is inverted when it is put on to a rubber blanket which is attached to another cylinder. After that, sheets of paper of desired dimensions are put together and the rubber blankets transmit the image to the sheets on a third cylinder, where it comes out as the correct side.
Last 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.
