When to stop for foil pinholes on a pharma label
On a pharma label, stop if a foil pinhole lands on the mark or the type. Judge the rest against the foil sample. If it hits the lot number, the expiry, or a barcode, do not release it. Small spots in the foil show the base color.

Look first at whether it hit a critical spot
Small spots in the foil show the base color. A print white spot is in the ink layer, not in the foil. On a pharma label, the critical spots are the lot number, the expiry, or a barcode. If the decorative area has no hickey chart, do not invent a millimetre number on the spot.
Side by side
| What you see | Call | Do not |
|---|---|---|
| Small spots in the foil show the base color. | On the mark or the type, stop. The rest follows the foil sample. | Add ink or impression the moment you see it |
| It lands on the lot number, the expiry, or a barcode | This one cannot be released | Wait for the next process to find it |
| Only on decoration, and there is no hickey chart | Keep a sample and confirm | Write your own millimetre number |
Do this first on this pass
- Confirm it is a foil pinhole: the base color shows through the foil.
- Check temperature, pressure, and the foil first. Do not add ink to the print.
- Note the temperature, the pressure, and the foil batch.
