Printing service is used by most organizations for varied reasons such as marketing and corporate communications. Offset printing ink is the most frequently used printing technique and learning about it is therefore helpful and important.

The clients and the printers like offset printing ink because of its cost effectiveness for the production of large number of prints. This is the reason good printing service providers recommend the use of offset printing for bulk prints.

The ink used 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 transferred indirectly from the plates to the paper by use of rubber blankets as the agents.

First step is to prepare the graphics. Film negatives were used in the past for making images and then copying them to aluminum based printing plates. In the current times, the printers can use the image setting system for making the plates directly. This plate is then placed on a cylinder in the proper configuration. Next, the water is spread on the image plates, which is followed by the ink. The image receives the ink while the rest of the area receives a thin coating of water, which ensures that the ink does not spread outside the images.
