How to tell set-off apart on a pharma label
Show-through soaks from the face to the back, and the image is paler and softer. The wrong name sends the adjustment to the wrong place. Check delivery, spray powder, and drying first. Do not change the ink on the face to hide it.
On a pharma label, tell set-off apart like this: show-through soaks from the face to the back, and the image is paler and softer. Until they are apart, do not adjust the press for the wrong cause.
The wrong name sends the adjustment to the wrong place
The back carries the image of the previous sheet, and you can often feel it. If you treat that as another defect, you skip this step: check delivery, spray powder, and drying first, and do not change the ink on the face to hide it. The regulatory text and the barcode decide whether the label can go, but they do not decide what the defect is called.
How to separate them
| What you see | Closer to | Do not separate them like this |
|---|---|---|
| The back carries the previous sheet’s image, and you can often feel it | Set-off | Name it from one white spot |
| Show-through soaks from the face to the back, and the image is paler and softer | Handle it as that other defect | Use the same adjustment |
| The place is the regulatory text and the barcode | Keep this place safe first | Ignore the place in order to name it |
Look at it on the spot
- Look with the eye or a loupe: the back carries the previous sheet’s image, and you can often feel it.
- Rule out show-through: that soaks from the face to the back, and the image is paler and softer.
- Check delivery, spray powder, and drying first. Do not change the ink on the face to hide it.
