Definitions
- the subject of the present patent application is a high-pressure mold for printing processes, a process for producing the high-pressure mold and the use of the high-pressure mold in printing processes.
- high-pressure molds are used in which the printing parts are raised compared to the non-printing parts. It is assumed that a high-pressure mold with a flat surface is provided by indentations in the area of the non-printing parts.
- the high-pressure molds consist of a two-layer structure, i.e. of a carrier layer and a dye or varnish transfer layer on it.
- the carrier layer can be a metal or plastic film which gives the printing form a certain stability, while the ink or lacquer-transmitting layer is usually a polymer which can be removed by suitable means.
- This dye or varnish transfer layer is removed by chemical or mechanical processes to determine the non-printing parts of the high pressure mold.
- sharp or pointed objects e.g. Knives or awls are used, which can also damage the carrier layer when the dye or varnish transfer layer is removed.
- the high-pressure form can tear or tear if it is inserted into the printing unit under mechanical tension. The consequences of this tearing apart from the increased use of material and the loss of time for the production of a new high-pressure mold are also the machine downtimes and the possible damage to the printing press.
- the object of the present invention is to provide a high-pressure mold which is less sensitive to the mechanical removal of the dye or lacquer-transmitting layer and thus overcomes the disadvantages of the prior art described.
- the object according to the invention is achieved by a high-pressure mold according to claim 1, a process for producing the high-pressure mold according to claim 6 and the use of the high-pressure mold according to claim 9.
- the further claims represent preferred embodiments.
- Figure 1 shows schematically the structure of the high pressure mold according to the invention.
- the high-pressure mold according to the invention has a protective layer 3 between the carrier layer 1 and the dye or lacquer-transmitting layer 2, which protects the carrier layer 1 from mechanical damage.
- a protective layer 3 between the carrier layer 1 and the dye or lacquer-transmitting layer 2, which protects the carrier layer 1 from mechanical damage.
- a means for connecting the respective layers can be located between the carrier layer 1 and the protective layer 3 or between the dye or lacquer-transmitting layer 2 and the protective layer 3 of the high-pressure mold according to the invention.
- the layers of the high pressure form according to the invention can be chemically, e.g. be connected by an adhesive, as well as physically by lamination or amination.
- the protective layer can preferably consist of biaxially stretched polyester or of metals such as aluminum or stainless steel. It is crucial that the material - 3 - rial is suitable to protect the carrier layer 1 from mechanical damage.
- the high-pressure mold according to the invention is produced by laminating, laminating or coating the carrier layer 1 with a protective layer 3 and the application of a dye or lacquer-transferring layer 2 to the composite of carrier layer 1 and protective layer 3.
- a means for bonding can be applied between the carrier layer 1 and the protective layer 3 and / or between the protective layer 3 and the dye or lacquer-transmitting layer 2.
