Definitions
- the present invention relates to a method for electrostatic substrate transfer, as in the preamble of independent claim 1 is defined, and an apparatus for performing this method.
- Methods of application are particularly common in printing technology a substrate on a medium known in which Substrate from a substrate transfer roller to one Printing form cylinder and transferred from there to the medium is that of an impression cylinder against the printing form cylinder is pressed.
- the substrate transfer roller, the printing form cylinder and the impression cylinder can vary in various ways and depend among other things of the substrate, the medium and the desired application quality from.
- GB-A-608 902 discloses a printing device for the substrate from a printing form cylinder to a medium is transmitted, the transmission by means of an electrode is supported electrostatically. Instead of an impression cylinder stationary counter-bodies made of glass are provided.
- US-A-3 443 517 discloses a method of transmission of dye particles from a dye transfer roller onto a printing form cylinder and from there onto a medium known, in which the printing form cylinder from the inside all around is charged.
