Inline operations refer to operations that can be performed ‘in-line’ with the printing.
For some inline finishing operations, the press speed needs to be reduced to accommodate the speed of the inline finishing machine.
There is a new setting on the Operation Charge Options part of the component record called
‘Inline with Press’.
In order to allow the option to select whether the operation IS being performed inline or not, duplicate the component record and added a Component Reference to prompt whether to adjust the press speed (Component Reference = Inline) or leave the press to calculate its own speed (Component Reference = Offline)
When this operation is used on the quote, you select Inline or Offline accordingly.
When Offline is selected, the quote will calculate as it always has, with each part of the job being calculated individually.
When an operation set as Inline is used, the speed of the press is reduced to match that of the slower finishing operation. However when looking at the speed it may not display that because of the way the calculation is made.
In printing, you have Finished Sheets, Setup Spoils and Finish Spoils.
In the finishing operation you have Finished Sheets and some Finish Spoils, depending on other finishing operations spoils settings.
In the example following, the press speed is set to run at 7000/hr while the Perforate operation is set to run at 2000/hr.
To illustrate the calculation the Job Quantity has been set to 2000.
The job is produced 1 up A3 on an SRA3 sheet.
Looking at the perforating operation first, time is 1:01 and you can see the Click Count is 2025 (there are an additional 25 sheets of Finishing Spoils for THIS finishing operation)
(Note Click are added to see the quantity)
More importantly is the time at 1:01 – this is the SAME time as the finishing operation calculates.
The press ‘speed’ is a calculation of the calculated elapsed time of the operation to run the Total Sheets (2177 above) thru the press.
Total Sheets are made up of required sheets to produce the job, press setup spoils and finishing spoils for all finishing operations.
Total sheets | 2177 |
Time to print | 1:01 at 2150 / hr |
Sheets to perforate | 2025 |
Time to perforate | 1:01 |
Note – if there are other finishing operations on the product, whether inline or not, they too will add to the Total Sheets, making the press speed change in relation to the elapsed time.
If there is more than one inline operation added to a product, the press speed will be calculated based on the duration of the slowest running inline finishing operation.
