Rotogravure Cylinder Engraving Process By Janoschka Youtube This film guides you through the whole production process of a rotogravure cylinder and an embossing roller. besides the preperation of the steelbase accordi. Gravure, unlike most other printing processes, prints fro .collective term for the various means of engraving or etching the image onto the gravure cylinder.
Surface Finishing Of Rotogravure Cylinder By Janoschka Youtube The steel base is coated with copper by means of electro plating. the copper layer is either the material to be engraved, etched or embossed, or the basis fo. 1. electromechanical engraving electromechanical engraving as well as high resolution ‘xtreme engraving’ and ‘transcribe’ process impress through their high quality of detail reproduction and counter sharpness. our gravure machines can engrave up to 12,000 cells per second in the copper layer of the gravure cylinder. 2. direct laser. Laser gravure using the direct laser system (dls) is an extremely fast, high quality gravure process. the prerequisite for it is either a new steelbase or an already used and re prepared cylinder. an electroplating process ensures the copper layer on the cylinder, which lies exactly 50µ below the desired diameter. the zinc layer of 55µ. The basis for electro mechanical engraving is a copper coated steelbase with a 0.1 mm strong layer of gravure copper and special surface processing. the so called cells are engraved in this surface with a diamond stylus. depending on how fast the cylinder turns around its own axis, the cells are formed longer or more compactly. the diamond.
