Offset printing is mainly used for printing of paper-based materials. Sheetfed offset presses can be printed in different formats and are more flexible. At present, the printing format of most web offset presses is fixed. Its applications are limited. With the development of technology, the web offset printing press is also continuously improved. Web offset presses that can change the printing format have now been developed. At the same time, we developed a web offset press for seamless cylinders. The printing cylinder of this web offset printing machine is seamless, and in this respect is already the same as the web gravure printing machine. Offset presses are also constantly improving in printing functions. Corrugated cardboard can be printed by improving and adding some parts. By improving and adding a UV drying device, UV prints can be printed. The above improvements continuously expand the use of offset printing machines in the field of packaging printing. Water-based inks for offset printing will soon enter practical applications.
