What a camera needs to see set-off on a textured wine label
To see set-off on a textured wine label, a front camera cannot see the back. You need a back station or a spot check. If you cannot see it, change the light or the resolution first. Do not loosen the threshold first.

If you cannot see it, change the optics first
The back carries the image of the sheet before, and you can often feel it. If the picture cannot separate that, loosening the threshold only paints the wine name and the fine type red. A front camera cannot see the back. You need a back station or a spot check.
Optics
| Need | Enough looks like | Not enough looks like |
|---|---|---|
| A front camera cannot see the back. You need a back station or a spot check. | The back carries the previous sheet, and you can often feel it. | Only a blurry circle |
| About 3 pixels across | It shows steadily | It comes and goes, yet someone writes that it can be detected |
| The wine name and the fine type are in view | The critical place is in view | Only the decorative edge is lit |
Try it on a sample
- Confirm the picture separates this: the back carries the previous sheet, and you can often feel it.
- Count about how many pixels it covers.
- If you cannot see it, change the light or the focus. Do not change the threshold.
