How to tell an anilox line from a lookalike on a food web
On a food flexible package, separate the anilox line: a nick on the plate repeats with the plate circumference, and that length is not necessarily the roller circumference. Until you can tell them apart, don't adjust the press for the wrong cause.

Name it wrong and you adjust the wrong place
A fine line tied to the anilox is still there after a roll change. If you call it something else, you skip this step: measure the repeat and match it to a roller first. Don't add ink first. On a food flexible package, the ingredient panel and the heat-seal area decide whether you pass it. They do not decide what you call it.
How to separate them
| What you see | Closer to | How you separate |
|---|---|---|
| A fine line tied to the anilox is still there after a roll change. | anilox line | Name it from one white spot |
| A nick on the plate repeats with the plate circumference. That length is not necessarily the roller circumference. | Treat it as that other defect | Use the same adjustment |
| It sits on the ingredient panel and the heat-seal area | Hold this spot first | Ignore the location just to name it |
Confirm on the spot
- Look with the eye or a loupe: a fine line tied to the anilox is still there after a roll change.
- Rule out: a nick on the plate repeats with the plate circumference, and that length is not necessarily the roller circumference.
- Measure the repeat and match it to a roller first. Don't add ink first.
