How to inspect inserts packed into one carton

For inserts packed into one carton, inspect the page count, the order, and the version. It is not enough that each page prints cleanly. Without a count record, the set cannot be called complete.

Several instruction sheets in one carton

For the inserts packed into one carton, what has to be inspected is the page count, the order, and the version. It is not enough that each page prints cleanly. A missing page is found most directly by weighing or by a visual count. Without a count record, you cannot write that the inserts in this carton are complete.

Why it is judged this way

When the customer opens the carton and finds a leaflet missing, a passing cover colour difference will not matter. The collating station needs one method that finds a missing page: weighing, a photo count, or a mechanical count. Pick one and write it into the process. Print inspection does not replace this step.

What to compare

What you see What to call it What not to do
A page is missing or the order is wrong The carton cannot be sealed Release it because one page looks fine
The version does not match this batch Stop Pass it because the page count is right
A count record exists The set can be traced Rely on the operator's memory

At job change or when a roll is opened

  1. Specify one method: weighing, a photo, or a count.
  2. Leave one page out on purpose and confirm it is found.
  3. Write the record on this carton.
