Problems solved by technology

On this basis, the prior art cannot tell whether the front or the back is incorrect, or whether the printing process should have produced the "strawberry" container and the print head has been switched further internally with the wrong step size

Embodiment Construction

[0117] figure 1 A flowchart showing the RIP process in a PS / PDF workflow. The originally rendered PostScript document is converted into a PDF document by means of a so-called normalizer, by interpretation of the PS file or into PDF. This in turn is converted by a rendering process into a bytemap (halftone) and again into a bitmap (rasterizer) via a screening method via a so-called rasterizer. The resulting raster file can be used by the printing head of the printing assembly in a printing process known as a RIP file, which essentially employs a determined sequence and drop size of individual printing nozzles actuated in each possible printing color .

[0118] figure 2 An exemplary illustration of a container 10 to be printed is shown, for which the method or device according to the invention is particularly advantageous. The figure shows a container 10 in the form of a spiral, a so-called twisted container. Such containers can only be labeled with a so-called sleeve, whi...

Abstract

Monitoring device (50, 52) for monitoring a plurality of containers (10) which have been printed with at least one first image element (B1-B8) by a direct printing machine (20), having a transport device (40) which supplies and/or discharges the printed containers (10) to be monitored along a predefined transport path, in particular individually and successively, to the monitoring device (50, 52),wherein the monitoring device (50, 52) monitors the printed containers (10) at least with respect to the first image element (B1-B8) applied by the direct printing machine (20), and has a memory device (53) which stores the at least one set of first image elements (B1-B8) to be monitored. According to the invention, for each container (10) to be monitored, the monitoring device (50, 52) carries out monitoring taking into account at least one image element (B1-B8) uniquely assigned to this container (10) to be monitored from the set of first image elements (B1-B8) to be monitored.

Description

technical field [0001] The present invention relates to a device and a method for monitoring printed containers, in particular for sequential monitoring of preferably multicolor printed containers, or for processing containers. Background technique [0002] Devices and methods for printing directly onto containers are known from the prior art. The advantage of direct printing lies in the free design of labels. Firstly, so-called "no-label look" labels are unnecessary, and secondly, this limits the labels of the present invention to the fact that they can only be applied to surfaces that, when processed, produce a flat and advantageously adhesive sheet. Conversely, by direct printing it is possible, for example, to print raised or embossed logos on containers or spherical surfaces. Further designs are possible. Therefore, today, known spirally turned or twisted containers can only be marked with a sleeve (a plastic sleeve that is heat-shrunk onto the container), with the d...
