EDELMANN GRAPHICS GmbH, the narrow web offset specialist, presents the range of web presses: STAR-PRINT (Sleeve Technology Advanced Rotation), as a brand new development.
The unique feature in this innovative press is that it utilizes sleeves for the traditional plate and blanket cylinders, in a printing insert. these sleeves are fitted with bearers. The available print repeats are from 24" - 44". The inserts cover a range of 8", so that a 24" insert will allow a repeat range up to 32", similarly a 44" insert will allow a range down to 36". These three layered sleeves have relatively thin walls and have no fillers in the material. The sleeves are fitted with hardened bearers left and right, which are precisely screwed into position and are hydraulically locked onto mandrels. In this way perfect Offset quality is achieved, which is the new yard stick in label and package printing.
The press can be configured to run wet on wet or with intermediate drying and is available in web widths of 20 1/2", 30" and 36". The STAR-PRINT has four form rollers, one of which is a combination roller. Every tower is driven with 3 servo motors, one drives the ink train, the second the plate and blanket sleeve and the third drives the impression cylinder. The servo motors are not mounted in the print inserts so they do not need to be de/re-mounted.
The ink fountain roller is independently driven which allows very precise control over the ink feed, this is coupled to the standard ink pre-setting from digital workflow. The impression cylinder has a very exact motorized throw-on, which can be stored for repeat jobs. The press has a maximum production speed of 1300 ft/min.
As the STAR-PRINT was conceived for variable print inserts with sleeves, it is also the ideal Hybrid Solution, as it will take inserts for offset, flexo, gravure and silk screen. This feature will provide a much faster ROI as the press offers much more flexibility for now and the future.
The STAR-PRINT created much interest and the distribution channel in Germany is very busy providing further information on the Sleeve Concept.
