How the camera sees colour drift on food flexible packaging
To see colour drift on food flexible packaging, the camera can only flag that it changed. It cannot stand in for the spectrophotometer number that lets the job go. If you cannot see it, change the light or the resolution first. Do not loosen the threshold first.

Fix the optics first
The colour in the same place slowly leaves the signed sheet as the metres go. If the picture cannot separate it, loosening the threshold only paints the ingredient list and the heat-seal area red.

Try it on a sample
- Confirm the picture can separate it: The colour in the same place slowly leaves the signed sheet as the metres go.
- Count about how many pixels it covers.
- If you cannot see it, change the light or the focus. Do not change the threshold.
