How the camera sees a slurred dot on food flexible packaging
To see a slurred dot on food flexible packaging, you must see a single dot. A solid will not tell you. If you cannot see it, change the light or the resolution first. Do not loosen the threshold first.

Fix the optics first
The dot stretches in only one direction. If the picture cannot separate it, loosening the threshold only paints the ingredient list and the heat-seal area red. You must see a single dot. A solid will not tell you.
Optics
| Need | Enough | Not enough |
|---|---|---|
| You must see a single dot. A solid will not tell you. | The dot stretches in only one direction. | Only a blurred circle left |
| About 3 pixels across | It stays | It comes and goes, and you still write that it can be caught |
| the ingredient list and the heat-seal area in the field of view | The critical place is seen | Only the decorative edge is lit |
Try it on a sample
- Confirm the picture can separate it: The dot stretches in only one direction.
- Count about how many pixels it covers.
- If you cannot see it, change the light or the focus. Do not change the threshold.
