Many significant operations in a business such as maintaining flow of information intra-company and marketing the offerings of the company need printing service. Offset printing is the most frequently used printing technology and knowing about it is therefore helpful and important.
Offset printing can produce a large number of prints quickly, which makes it less costlier than other technologies and also more well known. Therefore good printing service providers suggest the use of offset printing for large volume of prints.
This printing technology uses oil-based ink, which the water can not dissolve. The offset printing is so called because the designs are transferred indirectly from the plates to the paper by use of rubber blankets as the agents.
The first step is preparing the images. Previously the images were prepared by creating film negatives and were then transmitted to printing plates made of aluminum. This is no longer required as the technology exists for making the plates in one step through an image setting system. After this, the plate is attached to a cylinder with the proper side facing upwards. Then the water and ink are dispersed on the image plates, in that order. The image receives the ink while the rest of the area receives a thin cover of water, which makes sure that the ink does not spill outside the images.
After being painted with the ink, the image is put on a rubber blanket which is on a different cylinder, resulting in the image to be inversed. Subsequently, sheets of paper of required dimensions are put together and the rubber blankets transmit the image to the sheets on a third cylinder, where it comes out as the right side.
The task of printing is finished by the printing company by consolidating the printed sheets using staples or paste or in any other way as per the needs of the client.
