What to adjust first when pinholes show on a cosmetics carton
When pinholes show on a cosmetics carton, on film check corona and viscosity first. Don't add ink as the only move. Change only this one place, then look again at the same spot. The solid is full of pin-tip white spots.

Move one thing first
A field of pinholes in the seal area: stop. In decoration, follow the defect sheet. On a cosmetics carton, if it has already hit the brand mark or a brand-color solid, stop first, then adjust. Don't trial it while the press is running. A single void is larger, and there are often only a few.
Order
| Do this first | Don't yet | Why |
|---|---|---|
| On film, check corona and viscosity first. Don't add ink as the only move. | Change ink, pressure and speed together | Change three things at once and you won't know which one did it |
| It has already landed on the brand mark or a brand-color solid | Trial it while the job is still running | Scrap keeps moving |
| Note the material lot, the corona and the unit. | Only say you already adjusted it | The next shift can't pick it up |
Leave this when you're done
- On film, check corona and viscosity first. Don't add ink as the only move.
- At the same spot, confirm whether the pinholes have eased.
- Note the material lot, the corona and the unit.
