Many important tasks in a business such as maintaining flow of information within the company and marketing the offerings of the company need printing service. Hence, it is good to have some basic knowledge of how printing works, particularly offset printing, which is one of the most widely employed printing techniques.
The customers and the printers like offset printing because of its cost effectiveness for printing of large number of prints. Hence for bulk orders any good printing company would recommend you to go for offset printing.
Offset printing employs oil based ink, which does not blend with water. The offset printing is so called because the designs are transferred in an indirect way from the plates to the paper by use of rubber blankets as the medium.
The process begins by preparing the designs. Film negatives were employed in the past 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. After this, the plate is stuck to a cylinder with the correct side facing upwards. Thereafter water, and then ink, is spread on the image plates. The ink is poured over the image and to restrict it from overflowing, a thin layer of water is put over the remaining part of the plate.
Next, the image is turned around when it is put on to a rubber blanket which is attached to another cylinder. Subsequently, sheets of paper of desired dimensions 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.
The work of printing is completed by the printing company by providing the final touches to the printed sheets using staples or paste or in any other way as per the requirements of the client.
