Brief Introduction of Equipment

Rugao Zhongluo Printing Machinery Co., Ltd. is located in Rugao, Jiangsu, the hometown of longevity in the world. It is a high-tech enterprise specializing in the production of "Rota" brand double-sided offset printing presses, Vision, and VSOP commercial web printing presses.

In 2018, our company was digesting and absorbing international advanced technology, and developed a printing speed of up to 300m/min (paper size 720×1050mm), variable size (perimeter 508-720mm) web hard press soft LT1050 rotary unit type offset press .

This model can replace the printing cylinder and realize the printing and cutting of multiple sizes on the same machine, which solves the customer's concerns about product size and selection when purchasing products. It can be folded or cut into single sheets. A number of automation and intelligence make high-speed, high-efficiency, high-intelligence and high-quality double-sided rotary printing a reality, filling the domestic gap!
