Printing service is used by most organizations for varied reasons such as marketing and intra-company communications. Offset printing is the most commonly used printing technology and knowing about it is therefore helpful and important.
Offset printing can generate a large number of prints quickly, which makes it less costlier than other technologies and also more popular. Therefore good printing service suppliers suggest the use of offset printing for bulk prints.
Offset printing employs oil based ink, which does not mix with water. The offset printing is so called because the designs are transmitted indirectly from the plates to the paper by use of rubber blankets as the medium.
The process begins by developing the designs. Earlier the images were prepared by creating film negatives and were then transmitted to aluminum printing plates. In the current times, the printers can use the image setting system for preparing the plates directly. The next step is to attach the plate on to a cylinder in the right manner. Thereafter water, and then ink, is spread on the image plates. The image receives the ink while the rest of the area receives a thin film of water, which makes sure that the ink does not spread outside the images.
The image is then taken from the plates to the rubber blanket rolled on another cylinder, so that it is reversed. The image is reversed to its right side by transferring the image to sheets that have been cut according to the need and are placed on a different cylinder.
Last steps of the printing job involve things such as stapling, gluing or arranging the printed sheets according to the instructions of the client, and any printing company should easily manage these.
