The Method Of Offset Printing
Many important tasks in a business such as maintaining flow of information within the company and marketing the products of the company require printing service. Therefore it is helpful to learn about the basic working of the frequently used printing process called offset printing.
Offset printing is so well known among printing service companies and customers because for large quantities, it is more economical than other options. Therefore good printing service suppliers recommend the use of offset printing for large volume of prints.
The ink employed during offset printing has oil as the medium and is insoluble in water. The offset printing gets its name from the fact that the designs are transmitted indirectly from the plates to the paper by use of rubber blankets as the agents.
The first step is preparing the images. Film negatives were used in the past for making images and then reproducing them to aluminum based printing plates. In the present times, the printers can make use of the image setting system for preparing the plates directly. This plate is then put on a cylinder in the proper configuration. Then the water and ink are spread on the image plates, one after another. While the ink gets fixed to the image, the water gets stuck to that part of the plate where there is 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. Afterwards, sheets of paper of required 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 work of printing is completed by the printing company by consolidating the printed sheets using staples or paste or in any other way as per the requirements of the client.
