Description
Technical Field
The invention relates to a method for operating a printing press having a machine control system.
The present invention is in the technical field of the graphics industry, in particular in the field of preparing and executing a plurality of print jobs, wherein the presetting of the print jobs is performed on a printing press.
Background
The printing press presets the print job by means of a machine control system with the aid of a computer-aided presets that are known and provided digitally. The presetting may be performed by the printer manufacturer. It may happen that during production with the printer, some presets may no longer be correct, i.e. that the best product is not produced. Thus, the printer operator may alter these presets if desired, for example, if the presets of the waiting print job are not optimal from the perspective of the operator.
The printer or its machine control system may communicate with an operator of the machine. DE 10 2004 033 56A1 discloses that the printing press requests missing data of a print job from the operator. DE 10 2007 058 708A1 relates generally to communication between a machine and an operator.
The system "PAT" (performance advisor technology) developed by the lithopone printing press company for its printing presses analyzes and interprets the data obtained from the so-called log file. For example, if a deviation from a predetermined performance value is identified, a message may be generated and an improvement recommendation may be given. The development of the printer performance was then monitored. It identifies whether performance is improved. The advice will also be adjusted if necessary. Thus, the system knows which recommendations are good and which are not.
Despite the known measures, it may happen that the printing press is still not optimally preset.
Disclosure of Invention
It is therefore an object of the present invention to provide an improvement over the prior art, which in particular makes it possible to optimally preset a printing press.
According to the invention, this object is achieved by a method according to a preferred embodiment of the invention.
Advantageous and therefore preferred developments of the invention can be derived from the alternative embodiments as well as from the description and the figures.
The invention relates to a method for operating a printing press having a machine control system, wherein the machine control system in each case performs a computer-assisted presetting of the print jobs on the printing press when executing the print jobs, characterized in that, in the event of a plurality of print jobs and/or a plurality of operator interventions, repeated, operator-side changes of the preset or of the preset printing press are detected with the aid of the computer and are evaluated for a preset adjustment.
The invention advantageously makes it possible to optimally preset the printing press. According to the invention, the computer-aided detection of repeated, operator-side changes of the preset or preset printing press is carried out. Furthermore, according to the invention, they are subjected to computer-aided analysis to obtain preset-adjustments. Finally, according to the invention, the presets for the upcoming print job are modified based on the presets-adjustments. This method advantageously makes it possible to obtain improvements from repeated, operator-side changes and to change the presets in an optimal direction.
In the method according to the invention, the preset repeated operator-side changes are "monitored" and "queried" to some extent. Changes that result in preset optimizations may be applied to future presets, while changes that do not result in preset optimizations may be discarded. All of this is accomplished by using a digital computer. Preferably, a catalog of questions and answers is prepared to obtain information about operator intervention that can be evaluated computationally by the operator.
The method according to the invention can be used particularly advantageously for repeated, identical printing operations. The modification made by the operator to the presets of print job a may be employed after being checked as having a positive effect and the presets of further print jobs a may be adjusted accordingly. The other print jobs B, C and the like are preferably unaffected.
Hereinafter, a preferred expansion scheme (simply referred to as an expansion scheme) of the present invention is described.
One extension may be characterized in that the changes made by the operator with repeated, identical print jobs and/or repeated, identical operator interventions are computer-aided detected and analyzed. For example, it can be recognized that the operator always makes the same changes to the presets in a plurality of repeated print jobs a. By processing a questionnaire directory of computing technology information, it can be obtained whether such changes result in optimization. If so, the modification may be used to adjust the presets.
One extension may be characterized in that the changes made by the operator are computer-aided converted into preset-adjustments. For example, if the operator repeatedly changes, e.g. decreases, a certain value of the preset, the value may be adjusted, e.g. decreased, by the preset-adjustment for all future identical print jobs. For example, the value may be the duration of time to wash the blanket.
One extension may be characterized in that in the analysis, a predetermined inquiry is made to the operator and a predetermined answer is provided to the operator for selection, wherein the communication means is used. For example, the operator may be asked why a certain modification is to be made. For answering, the operator is provided with a list of prepared answers. From the answer selected by the operator, it can be deduced with a computational technique whether the modification is rational or whether the modification results in an optimization.
For example, it may happen that even though the blanket has been washed and should therefore be clean, the operator still initiates a washing process to wash the blanket. The machine control system will now determine from the questions and answers whether a re-wash is reasonable. If so, the presets may be adjusted or altered for the existing wash program. For example, the corresponding washing process may be enhanced.
Another example is to use a characteristic curve to preset the powder. If the operator makes changes to such presets, the machine control system will determine the cause of the changes and whether the changes are rational or result in optimization from the questions and answers. If so, the presets may be adjusted using the modifications.
Other examples are job changes, paper running settings or dampening mechanism settings, in which the changes are typically made by an operator. Also, the machine control system will determine from the questions and answers whether the changes made are reasonable or result in optimization. If so, the modification may be used to adjust the presets.
One extension may be characterized in that the answer selected by the operator is converted to a preset-adjustment with the aid of a computer. For example, repeated decrementing/incrementing of a value by an operator may result in a preset adjustment or decrementing/incrementing of the value for the future. For example, the operator may repeatedly alter the order of certain steps. For example, the operator may de-repeat a step.
An extension may be characterized in that a predetermined action recommendation is made to the operator in the analysis, wherein the communication means are used. Such action suggestions may be, for example: the parts or components of the printing press or the substrate are inspected to obtain information about their actual state. For example, an operator may detect and evaluate the cleaning result and input it into the machine control system. In this way, information can also be obtained when the machine control system or the printer is not provided with technical sensors, such as cameras.
In the above blanket wash example, the operator may be required to check himself whether the blanket is clean enough after washing. The operator may input his inspection result. It can thus be deduced from the calculation technique whether a certain washing program has to be adjusted or modified, for example intensified.
One extension may be characterized in that in the analysis, the changes made by the operator are checked for rationality with the aid of a computer. If the operator's intervention initially appears unreasonable, for example, a catalog of questions and matching answers may be presented to the operator. In this way it can be determined whether a certain intervention is useful for optimizing the presets. Accordingly, a certain intervention may be classified as a positive intervention or a negative intervention, in which case it may be incorporated into the preset-adjustment.
An extension may be characterized in that the preset-adjustment is recorded with the aid of a computer, wherein at least one protocol is generated and stored, preferably digitally stored.
An extension may be characterized in that at least one preset-adjustment is revoked with computer assistance by using the protocol.
An extension may be characterized in that in the analysis algorithms, models, simulations and/or artificial intelligence are implemented in computational technology.
The features and combinations of features disclosed in the above-mentioned technical field, summary and expansion paragraphs and in the following examples paragraphs form further advantageous expansions of the invention in any combination with each other.
