Meet the Press: The Past, Present, and Future of Commercial Printing. (Conquest Graphics, 6/7/2019)
Offset printing was developed from the late 1800s into the early 1900s and continues to be one of the predominant printing methods used today. In this process an inked image is transferred from a plate onto a rubber blanket and then transferred again onto paper. This process draws from the lithographic process, relying on the repulsion of oil and water.
