How to keep inspection running during a short job change
The template is ready before the changeover. The list is short enough to read in a few minutes. Metres where inspection started late are not counted as inspected.
Inspection stays running on a short job change because the template is built ahead, the changeover list is only a few lines, and the version number can be scanned. Do not build the template in the few minutes the press is stopped. A changeover that builds the template on the spot will start inspection late or skip it.
Why it is judged this way
The loss on a short job sits in the changeover. If inspection setup is slower than matching color, the operator will bypass. Have the next job’s template ready before the current job ends, and name it with the job number. Switching is only a choice and a check, not a lesson.
What to compare
| What you see | What to call it | What not to do |
|---|---|---|
| The next job’s template is already on the list | The switch can be fast | Learn it from scratch after the stop |
| The list is longer than half a page | Cut it down to the checks | Add more explanation |
| Inspection starts late | Mark the late stretch on its own | Write the whole roll as inspected |
At job change or when a roll is opened
- Build the next template before the current job ends.
- Choose the template by a scan.
- Record the metre where inspection actually started.
