What is Offset Printing?

Offset printing is one of the printing technologies in which a printed image is first transferred from a printing plate onto an intermediate surface. This intermediate material is generally softer and compressible than the printing plate material itself, and is often called a “blanket” material. The image can then be transferred from the ‘blanket’ material to a printed surface with less pressure than would be needed otherwise. Today, the most commonly used ‘offset’ configurations are found on lithographic presses, although some digital and letterpress machines may also offset images onto blankets before printing the image.
