Privacy Policy | Imprint | Prinect Know How | Prinect Release Notes The Time Evaluation Report lets you evaluate your company's processes. The report provides a gapless visualization of times accrued at your machines. In this way, you can, for example, precisely track machine standstills and take corrective measures if necessary. The following screenshot shows an example of a Time Evaluation. Please note that the underlying configuration can be different from the one in your own company. Correlation Between Time Categories, Time Types, Actions, and Operations Apart from the correct configuration, a correct time evaluation depends above all on the work habits in the company. This means that the machine operator must correctly report all times to Analyze Point, e.g. by pressing the good sheet counter or the manual PDC button and completing the operation correctly. Below, we will describe the correlation between the components to illustrate how time reporting at the machine is translated. Operations (PDC messages) such as "Start basic makeready" or"start good production" at the machine were reported either manually by the machine operator or automatically by Analyze Point. The intervals between the operations are "translated" to actions. A new action starts when an operation is reported. It ends as soon as the next operation is reported at the machine. This does not apply to operations without assigned action. As a rule, these are automatic operations. In this case, the time expired after the operation has been reported is added to the previous action. The actions are visible in the machine operator's time sheet later and indicate the duration of each of the activities (see "Employee" tab). For time evaluation, the actions are allocated to a time type and a time category. This classification is relevant in all places of Analyze Point where times are evaluated, e.g. in Machine Evaluation, Operation Evaluation, etc. This breaks down the times into productive and non-productive times. This helps you assess your company's processes over a longer period of time. Considering this time "translation" from machine to time evaluation, correctly reporting all times (e.g. pressing the good sheets counter, pressing the manual PDC button, finishing an operation, etc.) becomes essential. This is the only way Analyze Point can provide a meaningful time evaluation at the end. The report will be useless if times are reported too late or are not reported at all. Explanation of Time Categories and Time Types Below, the meaning of time categories and time types will be explained. In accordance with the guidelines of the Federal Association for Print & Media, only the preconfigured times are discussed here. By default, the following time types, time categories and actions are preconfigured: Time category Time type Action Production time Setup time Basic makeready Execution time Good production Miscellaneous production time - Auxiliary time Auxiliary time - Down time Down time Pause Production time The production time is the time requirement immediately related to the processing of pending jobs. All production times are productive times. We differentiate between setup time, execution time, and miscellaneous production time. •Setup time The setup time is used to set up the production plant to process a job. •Execution time The execution time is the time needed to produce the product. •Miscellaneous production time Miscellaneous production time covers all times that are neither setup nor production times but can nevertheless be assigned to a job directly. These are, for example, drying times or times required to wait for the customer. Waiting times are regarded as "Miscellaneous production times" if they are caused by the customer. Auxiliary time Auxiliary time is the time required to establish and maintain the operational readiness. This time is in no way related to a job. Examples of auxiliary times: •Organizational issues such as waiting for paper or printing plates. •Technical issues such as machine maintenance or repair. •Workplace-related auxiliary times such as rubber blanket change, start up and shut down. Waiting times are regarded as auxiliary times if they are caused by disposition issues (waiting for paper or waiting for plates). Down time The down time is the period in a shift during which no production takes place. Examples of down times: •Pause •Internal meeting •Standstill times caused by lack of orders Waiting times are regarded as down times if they are caused by a lack of orders. Various procedures for collecting makeready times for a print operation change in offset printing For differentiated analysis of the times for the printing process steps, there are two procedures of collecting the time for the an operation change in Analyze Point. When configuring the press in the Device Assistant, you can choose one of these two ways. See "Start time for new job at the press" list box. Procedure 1: New print operation when clamping the first printing plate of a plate set (default setting) In this procedure, the time at which the first printing plate of a plate set is clamped on the press for a new print operation is transmitted from Press Center to Analyze Point. This point in time is registered in Analyze Point as the trigger for an operation change, i.e. the previous operation is completed and the subsequent operation begins. In this case, the makeready time, e.g. blanket washing at the end of the print operation and/or the washup of spot colors, is attributed to the previous print operation. Effects of this time attribution: In cases where a longer make-ready time is required for changeover to the subsequent job, e.g. because a changeover is made from printing exclusively with process colors to printing with one or more spot colors, this make-ready time is attributed to the previous operation and thus to the previous job, although the changeover is required for the next job. Procedure 2: New print operation when starting the Intellistart job change and end of production printing In this procedure, the time when a job change is triggered by Intellistart is registered as the start of the new operation in Analyze Point. Effects and benefit of this time attribution: This procedure always attributes the makeready time until the first plate is drawn in to the subsequent job that normally necessitated the changeover. In this way - e.g. at the beginning of a shift - the additional makeready time is assigned to the corresponding jobs. The evaluations in Analyze Point are then based on this allocation. •If both of the above-mentioned procedures are used at the same time at one site, e.g. if presses with different Press Center versions are available, different processing time assignments to the jobs will result. This means that these presses can only be compared with each other to a limited extent. If necessary, you can always activate procedure 1 for different presses in a print shop (new and older Press Center versions) in order to obtain comparable processing time evaluations. •Even if a press is subsequently switched from procedure 1 to procedure 2, the current evaluations of the processing times for the individual jobs are no longer fully comparable with the previous evaluations. See Generating a Report for Machine Productivity. When the report has been created, the right pane displays the Time Evaluation. Each table refers to exactly one machine. You can use the arrow keys to go to the next machine if you selected several machines in the left pane. General information (table header) The table header displays the machine name and the number of operations performed in the selected time period. If the number of operations contains a decimal place, the selected period of time contains only part of the operation. Only this part is taken into account in this calculation. Time evaluation of periods with operation Correct time recording always refers to an operation. In the table, these times form time type and time category groups. The values in the columns represent the machine status percentages. Explanation of the columns: Column Display Time category Time type group. The total time is indicated for each time category. Time type Indicates the time type assigned to the captured action. Action Name of the captured action. Number Number of occurrences of an action in the report period. If the start or end of the action lies outside the report period, this action is included. Duration Duration of all actions captured in the report period in industry hours. If the start or end of the action lies outside the report period, the time will be calculated proportionally. Washup Duration of the automatic washup programs. Note: If the washup occurs in parallel with other operations, the sum total of the percentages for the machine status times can be unequal to 100%. Plate change Duration of the plate change for automatic plate change systems. Note: If the plate change occurs in parallel with other operations, the sum total of the percentages for the machine status times can be unequal to 100%. Production Duration of good sheet and waste sheet production. Idling <= 5 minutes Machine standstill or idling up to a period of 5 minutes. The time of 5 minutes cannot be changed. Idling > 5 minutes Machine standstill or idling for more than 5 minutes The time of 5 minutes cannot be changed. Time evaluation of periods without operation At the table end, all times without operation are listed. High values in this area indicate that times were recorded incorrectly. You can find details about the possible causes in the section below. See Why are there periods without assigned operation?. Why are there periods without assigned operation? There are several reasons for the occurrence of times not allocated to an action. This includes: •The machine was switched on without processing a job or an operation being reported. •Actions are not assigned to a time type. In this case, the action has already been set up, and you must assign it to a time type. See Assigning a Time Type to a Time Category. •Actions are assigned to a time type which is not assigned to a time category. In this case, you must assign the time type to a time category. See Assigning a Time Type to a Time Category. •There are time periods without an action defined for it. Explanation: Operations (PDC messages) automatically reported by the machine (such as automatic wash-up) usually are not assigned to an action. This is correct because such messages are not to trigger a new action but are added to the previous one. However, if these operations are reported without reference to an operation, the operation assignment is missing for these times. A typical example is the machine washup every weekend. Configuring the time evaluation HEIDELBERG supplies the following preconfigured time classifications: Time category Time type Action Production time Setup time Basic makeready Execution time Good production Miscellaneous production time - Auxiliary time Auxiliary time - Down time Down time Pause We recommend that you expand this categorization in the context of a PDC project if these categories are insufficient for your company. For this purpose, contact the Prinect Service of your local HEIDELBERG agency. The following steps are necessary to set up a new button (PDC message) for time evaluation at the machine control station: 1.A new action has to be defined (e.g. Wait for Material). See Create or edit a new action (PDC Message). 2.A pertaining operation (PDC message) has to be defined and assigned to the action set up before. The name of the operation should be identical to the name of the action. See Create or edit a new action (PDC Message). (3)You may have to create a new time type if applicable. This is necessary only if the new PDC message cannot be assigned to an existing time type. See Assigning a Time Type to a Time Category. 4.The new PDC message must be assigned to the corresponding machines. See "Assigning operations" configuration step. (5)If the PDC message does not appear at the machine, resynchronize the PDC configuration. Only a Service technician may perform this step. See Performing a synchronization. The new operation is now available as a button on the machine and the machine operator can trigger the message submission. To correctly capture the times, the PDC message must always be reported to Analyze Point before the work in question is started.

Video Tutorial: The following video demonstrates, how to correctly record times at Prinect Press Center:
Analyze Point - Recording and Showing TimeNote: This procedure is activated by default and is the only procedure available for older presses. In these cases, Device Assistant does not offer this option.
Prerequisite: This procedure is available only for new presses with Press Center software versions S21A.08.000_SFC, S21B.06.000_SFC, S22A.02.000_SFC and S22B.00 (and later).
Note: Make sure to heed the following notes before switching from procedure 1 to procedure 2 in your print shop:
Note: The data for washing, plate change, production, idling <= 5 minutes and idling > 5 minutes are shown proportionally for each action and for each time type and time category in percent. "Washing", for example, can occur during basic makeready, or during "good production". The washing time is then evaluated in relation to actions.
Note: Define a new action if you carry out work without reference to a job often.
