Gravure Printing Cylinder Proofing Machine
The Proofing Machine is developed for specific need of the Roto-Gravure industries. This machine is useful to inspect the precisely quality of the electronically engraved or chemically etched cylinders. The sample proofs are produced quickly and the proof establishes the' perfect colors and ink standards to allow total elimination of production press downtime caused by cylinder problems.The machine is equipped with programmable logic controller (PLC), hydraulic controls and pneumatic controls systems, which take control of rotation and pressure adjustment of impression cylinder, and adjustment of cylinder support. The proofs length can be selected by rotating the drum in half or full rotation mode. The machine is equipped with doctor blade setting, pressure adjustment of pneumatic and hydraulic control and impression cylinder registration, a high magnification video registration with video monitor, fine tuning of cylinder position to produce precise proofs
New generation automatic proofing machine is to test and proof rotogravure cylinders after engraving, to check its correct pattern and get customers approval. To proof gravure cylinders used both shafted and hollow cylinders.
High-end proofing machine is a new generation automatic proofing machine upgraded from the old style, which combines the past experience of designer and intelligent CNC technology development. The machine is operated by a industrial touch-screen computer. It adopts imported linear guide, imported bearing ABB dynamo, and SMC pneumatic element. Particularly suitable for plastic, paper, leather, PVC, plastic and plastic packaging printing roller proofing, suitable for gravure business, decoration materials production enterprises, gravure packaging printing enterprises, wallpaper production enterprises, printing ink production enterprises.
