Embodiment Construction

[0027] figure 1 The sequence of a preferred embodiment of the method according to the invention is shown step by step.

[0028] First, in method step A, a substrate 2 for the subsequent printed product 1 is provided. The provision can take place as follows: The substrate is guided from a printing material feeder to a first printing unit of the printing press. The substrate can be, for example, a paper, cardboard or foil sheet or also a web material.

[0029] In method step B, a first printing form 3 is provided, in particular an offset printing form. The printing form can be arranged, for example, on a printing form cylinder of the first printing unit. The printing plate has an area 3 ′ which guides the first printing liquid 4 . These areas can be generated, for example, by imaging the printing plate. The first printing liquid can be applied to the printing plate by means of the application device. Finally, the printing plate 3 comes into contact with the substrate 2 and...

Abstract

The invention discloses a method for manufacturing a printed article. According to the invention, the method is characterized by including the following steps: providing a base material (2), such as a paper; printing a first printing liquid (4) to the base material, such as in offset printing, wherein a first region (4) is generated to separately have a first external profile and a first internal profile (4a, 4b); and printing a second printing liquid (7) to the base material, such as in flexography, a second region (7) is generated to separately have a second external profile (7a), and the second external profile is disposed between the first internal profile and the first external profile. According to the invention, the method herein can produce high-quality printed article, especially fined manufactured printed article in a beneficial manner, and the high-quality printed article does not have defects.

Description

technical field [0001] The invention relates to a method for producing printed matter having the features of claim 1 . [0002] The invention belongs to the technical field of printing, namely the transfer of printing media, especially printing liquid, onto printing materials or substrates. Various printing methods are known, such as offset lithography or flexographic printing. Furthermore, it is also known to finish printed matter, for example by varnishing, and to use different printing methods for this. Background technique [0003] DE 103 60 050 B3 already discloses an offset printing method and an offset printing press with a plurality of offset printing units and subsequent varnishing units. The printing material is printed with oil-based offset printing inks in one of the offset printing units and in the subsequent offset printing, the partially printed side is coated with a transparent oil-based matt varnish. Finally, the entire printed surface, including the surf...
