When to stop for dry-back on a cosmetics carton
On a cosmetics carton, stop if dry-back is outside tolerance after drying. A wet sample that passed does not count. Don't pass it if it hits the brand mark or a brand-color solid. The color just printed and the color after dry are not the same. After dry it is usually darker or duller.

First see whether it hit the critical spot
The color just printed and the color after dry are not the same. After dry it is usually darker or duller. A color shift during the run changes on the press, not only after it dries. On a cosmetics carton, the critical spot is the brand mark or a brand-color solid. On decoration, with no defect sheet, don't invent a millimetre limit on the spot.

| It lands on the brand mark or a brand-color solid | Don't pass this one | Wait for the next process to find it |
| Only on decoration, and there is no defect sheet | Keep a sample and confirm | Write your own millimetre number |
Do this on this pass
- Confirm it is dry-back: the color just printed and the color after dry are not the same. After dry it is usually darker or duller.
- Measure again after it is dry. Don't treat the wet reading as the final color.
- Note whether the reading was wet or dry, and the time between them.
