What a camera needs to see doubling on a cosmetics carton
To see doubling on a cosmetics carton, the camera must separate two dots. If it is blurry, focus first. 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
There is a faint second dot beside the dot. If the picture cannot separate them, loosening the threshold only paints the brand color of the cosmetics carton red. You must separate two dots. If it is blurry, focus first.
Optics
| Need | Enough looks like | Not enough looks like |
|---|---|---|
| Separate two dots. If it is blurry, focus first. | A faint second dot sits beside the dot. | Only a blurry circle |
| About 3 pixels across | It shows steadily | It comes and goes, yet someone writes that it can be detected |
| The brand color is in view | The critical place is in view | Only the decorative edge is lit |
Try it on a sample
- Confirm the picture separates this: a faint second dot sits beside the dot.
- Count about how many pixels it covers.
- If you cannot see it, change the light or the focus. Do not change the threshold.
