In the previous article, we had walked you through the introductions about digital printing as well as the basic differences between digital vs. offset printing. In this article, let’s discuss about the offset Printing.
Offset Printing Quality
Offset printing is also the highest quality printing process in the industry. It produces quality prints with rich, smooth and solids. The look and feel of any offset product comes across as more professional.
Lithography Process
The offset process is a lithographic process. Lithography is a process based on the repulsion of oil and water. Offset printing technology uses plates, usually made from aluminium, which are used to transfer an image onto a rubber blanket and then rolling that image onto a sheet of paper. It is called offset because the ink is not transferred directly onto the paper.
Web Offset
Web offset is a form of offset printing in which a continuous roll of paper is fed through the printing press. Pages are separated and cut to size after they have been printed. Web offset printing is used for high-volume publications such as mass-market books, magazines, newspapers, catalogs and brochures.
It is classified into two categories
- Heatset
- Coldset
Heatset
In this process, the ink is dried rapidly by forced-air heating.
Coldset
In this process, the ink dries more slowly by ordinary evaporation and absorption. Some web offset presses transfer text and images to only one side of the print medium at a time. Others can print on both sides simultaneously.
