Colour drift on a textured wine label

Name it wrong and you will adjust the wrong place

The colour in the same place walks slowly off the signed sample as the metres run. If you call it something else, you will skip this step: Use the agreed ΔE and the instrument. Do not use the screen. On a textured wine label, the wine name and the fine type decide whether it can go out, but they do not decide what to call it.

How to split them

What you see Closer to How to split
The colour in the same place walks slowly off the signed sample as the metres run. Colour drift Name it from a single white spot
Mottling inside one sheet is not drift that walks with the metres. Treat it as that other defect Use the same adjustment
The place is the wine name and the fine type Hold this place first Ignore the place just to name it

Confirm it on the spot

  1. Look, or use a loupe: The colour in the same place walks slowly off the signed sample as the metres run.
  2. Rule out: Mottling inside one sheet is not drift that walks with the metres.
  3. Use the agreed ΔE and the instrument. Do not use the screen.
