How to split cyan-magenta-black variation from the easy mix-up
The deviation to the signed sheet commonly uses ΔEab 5. Within the batch, cyan, magenta, and black commonly use 4. Both over, or only one over, and the action is not the same.

This is not the number next to it
Do not release within-batch variation on the signed-sheet 5, and do not put yellow's 5 on cyan, magenta, and black. Call it the wrong name and the later adjustment and the count both go wrong.
Split check
| Item | Do this | Do not |
|---|---|---|
| Cyan, magenta, and black variation | The deviation to the signed sheet commonly uses ΔEab 5. Within the batch, cyan, magenta, and black commonly use 4. Both over, or only one over, and the action is not the same. | Write only a feeling |
| The usual mistake | Do not release within-batch variation on the signed-sheet 5, and do not put yellow's 5 on cyan, magenta, and black. | Leave the wrong number in place |
| What to leave | The report must say it is within-batch variation, which two sheets, ΔEab, and the measuring conditions. A lone 4 is not enough. | Leave only the word pass |
Check before you name it
- Confirm you compared two sheets of the job, not the job against the signed sheet.
- For cyan, magenta, and black, use 4 as the usual upper limit.
- If the conditions differ, do not calculate.
