Engraver Machines
Engraving machines such as the K500 (packaging) or K6 (publication) by Hell Gravure Systems use a diamond stylus to cut cells. Every cell produces one printing process dot later in the operation. A K6 can have up to eighten engraving heads all cutting 8.000 cells per second to an accuracy of .1 µm and below. They are of course fully electronic computer controlled and the whole process of cylinder working is fully automated.
Now laser engraving machines are in developing but as per nowadays still the mechanical cutting has evidenced its force in economical conditions and quality. More than 4,000 engravers produce approx. 8 Mio printing cylinders global per yr.
