In the future, domestically-made self-adhesive gluing machine will also need to make efforts to improve the working speed and stability under the premise of ensuring basic functions.
Looking ahead to the post-Drupa 2000 post-press processing and packaging technology, traditional printing and finishing, binding, processing, and packaging will be developed in the direction of humanization, automation, high efficiency, and intensive. The printed products will be more exquisite and the machines will be more stable. Under the centralized control of computer systems, the automated printing, processing, and packaging production lines will become mainstream products. In some professional printing and packaging fields, we will see that a machine is a factory and a factory is a machine. The new concept of the "printing city" and "printing factory" proposed by Mann Rolland will become a reality.
It can be predicted that with the rapid development of computer networks, the printing company's business philosophy will also have great changes. Many printing companies will no longer need large-scale printing equipment, and ultra-large-scale printing centers will appear in traffic and information-developed areas. The products and services printed by the manufacturers will be remotely printed and processed remotely through the network, and the quality and cycle of the printing process will be better guaranteed.
