Offset printing is so popular among printing service companies and clients because for large volumes, it is more economical than other options. That is why for bulk orders any good printing company would advise you to opt for offset printing.
This printing technique uses oil-based ink, which is not soluble in water. In offset printing, rubber blankets play a transitional role in copying the image on the paper, which is to begin with on the plate.
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 transferred to aluminum plates. In the current times, the printers can use the image setting system for making the plates directly. The subsequent step is to attach the plate on to a cylinder in the right manner. Then the water and ink are dispersed on the image plates, in that order. The ink is spread over the image and to prevent it from overflowing, a thin layer of water is spread over the remaining part of the plate.
Next, the image is inverted when it is put on to a rubber blanket which is attached to another cylinder. Afterwards, sheets of paper of desired proportions are put together and the rubber blankets transfer the image to the sheets on a third cylinder, where it comes out as the correct side.
Printed sheets are stapled, pasted, or arranged in any other way as needed and the printing company sends them after giving some finishing touches.
