Offset printing is a kind of lithographic printing. It is simply said that offset printing is a printing method that uses rubber (blanket) to transfer images and texts on the printing plate to the substrate. It is also the existence of blanket. This printing method gets its name. Blanket has played an irreplaceable role in printing. The range of offset printing that we usually talk about now may be narrower, that is, offset printing with three rollers (printing plate, blanket and embossing), which is called offset printing in the south of China.
