How to tell a repeater from a lookalike on a cosmetics carton
On a cosmetics carton, separate the repeater: random lint does not repeat that exactly. Until you can tell them apart, don't adjust the press for the wrong cause. The same spot comes back at a fixed repeat length.

Name it wrong and you adjust the wrong place
The same spot comes back at a fixed repeat length. If you call it something else, you skip this step: measure the repeat and match it to the plate, the blanket or a roller. Don't wipe every unit blindly. On a cosmetics carton, the brand color decides whether you pass it. It does not decide what you call it.
How to separate them
| What you see | Closer to | How you separate |
|---|---|---|
| The same spot comes back at a fixed repeat length. | repeating spot | Name it from one white spot |
| Random lint does not repeat that exactly. | Treat it as that other defect | Use the same adjustment |
| It sits on the brand color | Hold this spot first | Ignore the location just to name it |
Confirm on the spot
- Look with the eye or a loupe: the same spot comes back at a fixed repeat length.
- Rule out: random lint does not repeat that exactly.
- Measure the repeat and match it to the plate, the blanket or a roller. Don't wipe every unit blindly.
