该机是上海建业义华机器厂于1964年底自行设计试制成功的新产品。目前我国印刷机械品种繁多,但规格不齐,自动四开印刷机自行设计试制更属少数。该机结构紧凑、外形美观、占地面积小、印刷效率高,适用于印刷照相铜版、精美画片、书刊插图、封面等高级印刷品。它的制成为今后系列化发展填补了缺门,对中小城市的印刷事业也提供了有利的物质基础。 This machine is a new product successfully designed by Shanghai Jianye Yihua Machinery Factory at the end of 1964. At present, China has a wide variety of printing machinery, but its specifications are not uniform, and automatic four-press printing machines are designed and trial-produced by themselves. The machine has a compact structure, beautiful appearance, small footprint, and high printing efficiency. It is suitable for printing high-quality prints such as photo copper plates, exquisite pictures, books and illustrations, and covers. Its preparation fills the gap for the future serialization development, and also provides a favorable material basis for the printing industry in small and medium-sized cities.
