Imposition printing has occupied a world in the printing field for many years. Although compared with digital printing, offset printing and other mainstream methods, the market share of imposition printing is relatively small, but imposition printing is very suitable for small-volume prints. Its advantage lies in the sharing of the plate-making fee and printing boot-up fee, which reduces the printing cost.

Specifically, imposition printing refers to the printing of different customers' prints or the same customer's different prints with the same number of prints and the same paper, which are collectively put together in the same set of layouts, printed out by an offset printing press, and then slitted. This process is called For imposition. After the emergence of information digitization technology, the printed matter can be stored as an electronic file. It can be automatically imposed by imposition software. It is fast and can be transmitted on the Internet. It is also called network imposition printing. As one of the most developed regions in the domestic printing industry, Shanghai is also staggering in the number of related companies undertaking imposition print orders.
With the emergence of the CTP direct plate making technology in the third printing technology revolution, the traditional manual imposition with film as the medium will gradually fade out of the offset printing market and become a collection of printed museums. If traditional manual imposition is only a creative idea, a method that does not require technology support, then network imposition is a technology that must use modern information technology.
