When banding on a pharma label means a stop
If a band crosses the main picture or the barcode, stop. If it touches the batch number, the expiry date, or the barcode, that label cannot go. With no dirt-spot table, do not invent a millimetre number.
On a pharma label, banding means a stop if a band crosses the main picture or the barcode. If it touches the batch number, the expiry date, or the barcode, that label cannot go. The look is a run of light and dark bands, across the web or around it.
Look first at whether it hits a critical place
The look is a run of light and dark bands, across the web or around it. Mottling has no fixed pitch. On a pharma label the critical places are the batch number, the expiry date, and the barcode. If a decorative area has no dirt-spot table, do not write a millimetre number for the moment.
What to compare
| What you see | What to call it | What not to do |
|---|---|---|
| A run of light and dark bands, across the web or around it | If a band crosses the main picture or the barcode, stop | Add ink or pressure just because you see it |
| It lands on the batch number, the expiry date, or the barcode | This label cannot go | Wait for a later step to find it |
| It is only on decoration and there is no dirt-spot table | Keep a sample and have it checked | Write your own millimetres |
Do this round first
- See whether it is banding: a run of light and dark bands, across the web or around it.
- Measure the pitch and match it to a roll or a gear. Do not change the formula first.
- Write the pitch and the color unit.
