When colour drift on a cosmetics carton means a stop
Stop if it is outside the agreed tolerance. With no written tolerance, keep a sample and do not invent a number. If it touches the brand mark or a brand-color solid, that carton cannot go. With no dirt-spot table, do not invent a millimetre number.
On a cosmetics carton, colour drift means a stop if it is outside the agreed tolerance. If there is no written tolerance, keep a sample and do not invent a number. If it touches the brand mark or a brand-color solid, that carton cannot go.
Look first at whether it hits a critical place
The color at the same place slowly leaves the signed sample as the metres advance. Mottling inside one sheet is not a drift that walks with the metres. On a cosmetics carton the critical places are the brand mark and a brand-color solid. If a decorative area has no dirt-spot table, do not write a millimetre number for the moment.
What to compare
| What you see | What to call it | What not to do |
|---|---|---|
| The color at the same place slowly leaves the signed sample as the metres advance | Stop if it is outside the agreed tolerance. With no written tolerance, keep a sample and do not invent a number | Add ink or pressure just because you see it |
| It lands on the brand mark or a brand-color solid | This carton cannot go | Wait for a later step to find it |
| It is only on decoration and there is no dirt-spot table | Keep a sample and have it checked | Write your own millimetres |
Do this round first
- See whether it is colour drift: the color at the same place slowly leaves the signed sample as the metres advance.
- Use the agreed ΔE and the instrument. Do not use the screen.
- Write the instrument, the condition, the metres, and the reading.
