Gravure proofing plays a very important role in gravure printing. Its sample sheet is the contact link between plate making company, printing company and customers. Gravure proofing machine is specially designed and manufactured for the proofing of gravure roller. It is used to inspect and identify the plate making quality, color management, and sample production of gravure printing roller by electronic engraving or chemical etching, and order different specifications according to the requirements of users Proofing length and diameter.
Gravure proofing machine is divided into two working modes: mechanical, pneumatic and hydraulic. It generally includes imprint drum positioning and clutch device, roller, plate roller, ink scraper, photoelectric focusing lens, 14 inch display screen and plate roller positioning and fine adjustment device, so as to ensure the transfer effect and accurate color registration.
Main Features
Proof speed:doctor blade angle and pressure showing&adjustable,more similar as gravure printing process.
High efficiency:operating module with high integration level and more efficient by 20%-30% than former ones.
Exact overprint:the guide rail ensures the stablity and precision of rubber drum.the cameralens of 50 times big ensures the microdots are high exact overprinting efficiency.
High transferal rate:the pressure between and rubber drum is much improved than before,which makes the microdots above 5% can be transfer printed.
Mechanical positioning is more stable.

There are two working modes of the gravure proofing machine: mechanical pneumatic and hydraulic. The hydraulic proofing machine adopts PLC program to operate automatically. The proofing pressure ensures the effect of pressure conversion. The color setting precision is high. It can be used to proofread film paper and other materials.Gravure machine is specially designed and manufactured for the proofing of gravure roller. It is used for the inspection and appraisal of the plate making quality of gravure roller after electronic engraving or chemical etching. Color management and sample production. And can adapt to the requirements of users to order different specifications of proofing length and diameter.
