1. the same work order should never be printed on multiple substrates, should it be required, the following is necessary:
if you anticipate that the material will not be sufficient, you should generate multiple work orders.
- make a calibration for the new substrate you will use
- make 2 different work orders, one for each substrate
For example, your client sends a purchase order for 400 000 codes but one substate only has enough material for 250 000 labels.
- create 1 work order for 250 000 codes for the first substrate
- create 1 work order for 150 000 codes for the second substrate
2. QA scans should be done according to the printing phase.
- Make Ready scans should be done at the beginning of the production when you are setting the job up
- Referencing scans when the setup is completed
- Press run throughout production (beginning and end of each reel)
- Finishing scans should be done AFTER the production is finished
- --> remember to submit the work order
3. avoid different line speeds and different roll tensions as much as possible
4. avoid stopping the print due to shift change. it is recommended
5. when operators encounter failed scans they should:
- stop the line to begin the investigation
- fix the problem
- mark where the issue occurred in order to be able to remove those labels from the batch that is later sent to the client
- continue producing
6. always print the entire work order in one go
- work orders must NEVER be split and printed in parts
- if multiple print runs are required because the purchase order was opened for a quarter, but deliveries are required monthly, separate work orders must be created for each print run
