Off set printing involves the transferring of an ink image from a printing plate to a printing surface via a rubber blanket. The off set printing technique is commonly used in the lithographic printing process with the aid of oil and water repulsion, planographic imaging, and ink rollers.
The offset printing press was developed in two different forms. The first version was invented in 1875 by an Britain’s Robert Barclay, but an American named Ira Washington Rubel introduced a superior version in 1904. While Barclay’s press was an important development, it was designed to print only on tin. On the other hand, Washington Rubel’s press was the first that was capable of printing on paper. Thus, Washington Rubel’s offset press was far more useful than Mr. Barclay’s invention.
As one would expect, there have been many advancements in offset printers, and the uses have becoming wider as a result. Actually, with the advent of digital printing, one would think that offset printing might be obsolete. However, offset printing still plays a key role in just about every type of commercial printing. Whether you are talking about print pamphlets, perfect bound book printing, lithography, or wide format printing services, offset printing is probably involved.
Despite being one of the oldest types of modern printing technologies, offset printing remains valuable for several reason. It creates images that are of a consistently high quality, fast and simple printing plate production, inexpensive costs, and the adjustability of the ink. With the rise of digital offset printing, it appears that off set printing will be around for quite some time to come.
