When pinholes on a pharma label mean a stop
A field of pinholes in the seal area means a stop. A decorative area follows the dirt-spot table. If they touch 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, a field of pinholes in the seal area means a stop. A decorative area follows the dirt-spot table. If they touch the batch number, the expiry date, or the barcode, that label cannot go. A solid holds many white spots the size of a pin tip.
Look first at whether they hit a critical place
A solid holds many white spots the size of a pin tip. A single void is larger, and there are often only a few. 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 |
|---|---|---|
| Many pin-tip white spots in a solid | A field of pinholes in the seal area means stop. A decorative area follows the dirt-spot table | Add ink or pressure just because you see them |
| They land on the batch number, the expiry date, or the barcode | This label cannot go | Wait for a later step to find them |
| They are 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 they are pinholes: many pin-tip white spots in a solid.
- On film, check corona and viscosity first. Do not add ink as the only move.
- Write the material batch, the corona, and the color unit.
