Equipment Introduction

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 press, Vision and VSOP commercial rotary press.

In 2018, after digesting and absorbing international advanced technology, our company developed a hard-pressing soft LT1050 rotary offset printing machine with a printing speed of up to 300 m/min (paper size 720 × 1050mm) and variable size (circumference 508-720mm).

This model can replace the printing cylinder, realize printing and cutting of various sizes on the same machine, solve the customer's concerns about product size and selection in purchasing products, can be folded or divided into single sheets, realize a number of automation and intelligence, make high-speed, high-efficiency, high-intelligence and high quality double-sided rotary printing a reality, and fill the domestic gap!
