Embodiment Construction

[0033] Figure 1a A device in a preferred embodiment for carrying out the method according to the invention is shown. What is shown is a front view, ie against the sheet transport direction.

[0034] The figure shows a sheet 1 (or a first sheet 1 a ) consisting of a printing material such as paper or cardboard. The front edge of the sheet is held by a plurality of grippers 8 spaced apart from each other in the transverse direction (that is, between the gripper fingers 9 and the gripper receptacles 10 of these grippers 8 ). It is clamped at edge 2 and is moved through the ink printing press in the conveying direction. These grippers are arranged on sheet transport means 11 , preferably transport rollers 11 .

[0035] In the region of the print head (not shown) of the ink printing press, the sheets are printed by ink droplets 6 according to the print image. Previously, the sheet could also be coated (for example by means of coating droplets 7 produced by an ink printing metho...

Abstract

The invention relates to a method for printing a print control strip onto a sheet of printing material. The print control strip 4 is divided into strip sections 41-4i and the strip sections are printed into gripper gaps 5 of at least one sheet edge 2, 3 of the sheet 1. In a variant embodiment, there is also printed a print control strip onto two sheets of printing material. The print control strip4 is divided into at least two portions 12, 13 of respective strip sections 4a-4i and the strip sections of a first portion 12 and of a second portion 13 are printed into respective gripper gaps 5 ofat least one sheet edge 2, 3 of a first sheet 1a and of a second sheet 1b, respectively. Waste production is eliminated or at least reduced and costs are thus lowered in a printing process.

Description

technical field [0001] The invention relates to a method with the features of claim 1 and a method with the features of claim 6 . [0002] The technical field to which the present invention pertains is that of the graphic industry, and here in particular the field of industrial ink printing (inkjet) on flat substrates, i.e. the printing of substrates in sheet form (preferably consisting of paper, cardboard, cardboard or plastic) Apply liquid ink. Background technique [0003] In the prior art, sheet-form printing materials (or printing material sheets), for example made of paper, are mainly placed on conveyor rollers, conveyor belts or so-called pallets (tablets) and are guided past the ink printing press and pass close to each other. The print head of the ink printer for printing. In this case, the sheets are usually held in the state of the art by means of (clamping) grippers, wherein so-called front edge grippers and rear edge grippers hold the sheets on the edge of the...
