What is Offest Printing ?
Posted: Fri Dec 01, 2017 8:12 am
Offset printing is a variant of the process developed by Gutenberg in the 15th Century. This process has undergone huge improvements over the ensuing centuries!
Offset printing is based on the idea that the image area to be printed should be transferred from a “plate” to a rubber blanket, and then to the sheet of paper. Offset printing is “wet” in that it uses a wet ink, usually either based on rubber or oil. At The Print Authority, we use oil based inks. If there are multiple ink colors, a different color is placed on each head of a press and they are transferred to the sheet of paper one color at a time. However, with modern multiple head presses, many ink colors can be transferred to the paper in one “pass” through the press.
