In other words, from the printer's point of view, this is a black box, he can only make judgments about it, and he can't change the criteria used for evaluation
Thus, such systems known from the prior art do not allow for adaptation to certain printing presses with certain specific requirements, or to the printing plant itself which implements certain requirements

Embodiment Construction

[0026] In a preferred embodiment variant, the method according to the invention is carried out by the assistance system 18 . here, in Figure 4 The schematic structure of this auxiliary system 18 is shown in . The system 18 includes a printing press 12 whose print quality is to be monitored and a control computer 16 of the printing press, on which an auxiliary system 18 is implemented as a software application. In this case, the control computer 16 also has an input device 17 and a display 15 . In this case, the control computer 16 and the display 15 (like the input device 17 ) can be integrated in the printing press 12 in a preferred embodiment as a remote control station. Furthermore, the control computer 16 is connected to a database 13 on which the parameters 5 , 6 , 7 for the coloring standard 9 to be used by the auxiliary system 18 are stored. In this case, the database 13 can be stored not only in the memory of the control computer 16 but also in an external memory w...

Abstract

A method monitors a color standard for a machine for processing printing material. The color standard results from various parameters of the printing operation and correspondingly associated set points. The color standard may be modified and individually adapted to every machine. The machine is equipped such that current values of the parameters of the color standard are measured and forwarded to a computer. The computer compares these values and predefined set points of the color standard, and based on this information, makes an assessment of the color and quality level achieved in the printing operation. The computer outputs control signals based on the monitoring. The control signals influence the machine control and / or the determining of the current values of the parameters of the color standard in a feedback loop. The color standard is modifiable by the operator by a different selection and weighting of the parameters and the set points.

Description

technical field [0001] The invention relates to a method for monitoring a color standard for a machine processing printing materials by means of a computer. [0002] The invention is in the technical field of automatic quality control. Background technique [0003] It has long been required in the printing industry to monitor the achieved print quality during the printing process in order to be able to intervene in the event of deviations from the desired printing result. In the simplest case, during the execution of a print job for visual quality control, the competent printer needs to check the produced print results from time to time. Since this cannot be met with modern printing machines due to their high throughput and especially with high quality requirements, various systems for quality control of the printing results have been developed over time. A common approach is, for example, to print out so-called printed inspection strips, which are placed on the printed su...
