Most organizations need a printing service on a regular basis, whether it is for marketing purposes or for internal communication. Offset printing is the most frequently used printing technique and knowing about it is therefore helpful and essential.
Offset printing is so well known among printing service companies and customers because for large quantities, it is more economical than other options. The clients giving bulk printing orders are recommended by the printers to opt for offset printing because of this reason.
The ink used during offset printing has oil as the medium and does not dissolve in water. In offset printing, rubber blankets act as intermediate for copying the image on the paper, which is to begin with on the plate.
The first step is developing the images. Film negatives were employed in the earlier times for making images and then duplicating 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 placed on a cylinder in the proper configuration. Next, the water is spread on the image plates, which is followed by the ink. The ink is spread over the image and to prevent it from overflowing, a thin layer of water is put over the remaining part of the plate.
After painting it with ink, the image is put on a rubber blanket which is on a different cylinder, leading the image to be inversed. Subsequently, sheets of paper of required dimensions are put together and the rubber blankets transmit the image to the sheets on a third cylinder, where it comes out as the right side.
Printed sheets are stapled, pasted, or arranged in any other manner as required and the printing company sends them after giving some finishing touches.
