What to inspect on a tag printed on both sides
A tag printed on both sides needs the front, the back, and a check that both sides are the same job. Inspecting only one side can leave the previous job's old version on the back.
A tag printed on both sides needs the front, the back, and a check that both sides are the same job. Inspecting only one side can leave the previous job's old version on the back. Both sides need a template, and the record has to say both sides were seen.

Why it is judged this way
Two-sided printing is often one side, then a turn. If the inspection after the turn still uses the front template, everything is wrong. Use a template for each side, and look for a mark that exists on only one side, so the two sides are not printed as the same face.
What to compare
| What you see | What to call it | What not to do |
|---|---|---|
| The back is an old version or blank | Stop | Release it because the front looks fine |
| Both sides are printed as the same face | Stop | Do only one inspection |
| Front and back are both right | Keep a record for both sides | Write only one pass |
At job change or when a roll is opened
- Build a template for the front and one for the back.
- Place a sample with a blank back and confirm the alarm.
- The delivery record says both sides were inspected.
