Embodiment Construction

[0027] figure 1 The method steps A to E or E′ of a preferred embodiment of the method according to the invention are schematically shown in a flow diagram. In addition to the individual method steps, it is likewise shown schematically which device technical measures can be used in each case and how the printed matter can be produced in sequence.

[0028] In method step A, first a printing material 10 with a surface 10 ′ is provided. The printing material 10 can be a sheet or a web. The printing material 10 can be made of paper, cardboard or synthetic material. A coating 11 is applied to the printing substrate 10 , comprising an acid 11 a. The coating 11 can be applied, for example, by means of a roller 13 . As an alternative to method step A, provision can also be made to provide a printing substrate which has already been coated with an acid layer.

[0029] In method step B, the printing material 10 or its surface 10 ′ is printed with a water-based ink 21 in the image re...

Abstract

The invention relates to a method for producing a printed matter (1) in which a printing substrate (10) is printed in the image area (20) in drop-on-demand with at least one colored and aqueous ink (21), by means of essentially A colorless and aqueous liquid (31) is loaded and dried in a drop-on-demand manner a) in the non-image area (30) and / or b) in the image area (20) with a small amount of ink, the printing material has (A) a coating (11) comprising at least one acid (11a), after printing (B) with ink and loading (C) with liquid, the printed material is both in the image area and in the non-image area An aqueous further liquid (41) is charged (E), said liquid and / or said further liquid comprising at least one substance (31a) which at least partially neutralizes said acid. Undesirable curl formation and gloss differences between varnished image locations and varnished non-image locations can thus be avoided.

Description

technical field [0001] The invention relates to a method for producing printed matter. [0002] The technical field to which the present invention pertains is that of the graphics industry and especially of ink printing (inkjet) in the graphics industry. In the known DOD (Drop-on-Demand, drop-on-demand) inkjet printing method, a printed image is generated on a printing material in that, depending on the image to be printed, the print head generates the finest ink droplets and the These ink droplets are transferred to the printing material without contact. The printing substrate can be made of paper, cardboard or synthetic material and can be in sheet or web form. Background technique [0003] DE 10 2010 060 409 A1 discloses a method for reducing waviness of a printing material in a printing press and a corresponding device for printing a printing material. In this case, at least one printing area of ​​the printing material is printed with ink, and the humidity of the prin...
