Abstract
The invention refers to a structure consisting of a set of pre-assembled elements on a polyester base used for the flexographic printing of corrugated cardboard, which is advantageously distinguished by the inclusion of adhesive foam directly between the printing plant and the polyester of the base to which the printing plate is fixed, which, among other advantages, improves the printed quality and reduces the pressure required for the cardboard to be covered by the ink with respect to conventional systems used until now for the same purpose.
Claims10
Pre-assembled structure for flexographic printing of corrugated cardboard which, by comprising:
- a photopolymer plate (2) on which the motif to be printed is engraved, formed in turn by a layer of photopolymer (3) incorporated on a first polyester sheet (4);
- a support base (5) that is fixed adhesively to the plate (2) and which, in turn, comprises a second polyester sheet (6);
- and a padded foam (7), is characterized by the fact that the padded foam (7), which is not part of the support base (5) but is an independent element, is incorporated sandwiched between the first polyester sheet (4) of the photopolymer plate (2) and the polyester sheet (6) of the support base (5), such that said foam (7) is directly in contact with said photopolymer plate (2).
