How to check a variable barcode on a pharmaceutical carton
A barcode or serial that differs on every pharmaceutical carton is checked one by one: it must read, and it must fit this batch's rule. Do not compare the picture only with the first carton.
A barcode or serial that differs on every pharmaceutical carton is checked one by one: it must read, and it must fit this batch's rule. Do not compare the picture only with the first carton. A picture compare will call the next legal number a misprint. The rule is this batch's serial specification.
Why it is judged this way
The variable code and the fixed brand on the carton are two layers. The fixed layer uses a template. The variable layer uses a read and a duplicate check. Doing only one layer misses something: either a smeared code is passed, or a correct new number is scrapped.
What to compare
| What you see | What to call it | What not to do |
|---|---|---|
| The code is inside the rule and reads | Pass | Reject it because it differs from the previous carton |
| The code repeats, skips a range, or will not read | Stop | Release it because it looks fine |
| Fixed artwork is missing | Stop it on appearance, separately | Ignore it because the code is correct |
At job change or when a roll is opened
- Enter this batch's serial rule.
- Place a code that will not read and confirm the alarm.
- Place a new code inside the rule and confirm it does not alarm.
