Printing service is used by most organizations for varied purposes such as marketing and intra-company communications. Hence, it is important to have some fundamental knowledge of how printing works, particularly offset printing, which is one of the most widely employed printing technologies.
Offset printing can produce a large number of prints quickly, which makes it more economical than other techniques and also more well known. Hence for bulk orders any good printing company would advise you to go for offset printing.
Offset printing employs oil based ink, which does not blend with water. Its name comes from the fact that in this process, images are not transferred directly from the plates to the paper but this is done through rubber blankets as a medium.
First step is to develop the graphics. When offset printing started, the images had to be developed by the use of film negatives and they were later put on aluminum plates. In the present times, the printers can use the image setting system for making the plates directly. The subsequent step is to transfer the plate on to a cylinder in the right manner. Then the water and ink are spread on the image plates, one after another. While the ink gets stuck to the image, the water gets attached to that part of the plate where there is no image so that the ink does not spread beyond the image.
The image is then transferred from the plates to the rubber blanket spun on another cylinder, so that it is reversed. Subsequently, 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 right side.
The final steps of the printing job involve things such as stapling, gluing or arranging the printed sheets according to the instructions of the customer, and any printing company should easily manage these.
