What to record for moiré on corrugated preprint
Moiré on corrugated preprint must at least keep this: the screen angle and the screen ruling of each color. Miss any one and the next shift cannot tell whether to change a part. A regular pattern shows in the dot area.

The record is for the next shift
Writing only “there is moiré” is useless. A regular pattern shows in the dot area. It also needs a location. If corrugated preprint hits the barcode or the large product name, the record must say already stopped or already released.
What to write down
| Item | What it is for | If it is missing |
|---|---|---|
| The screen angle and the screen ruling of each color. | Match it to the roll, the blade, or the material | Next time you guess from zero |
| Metres or sheet number | Find this spot again | The complaint will not match |
| Whether it hit the barcode or the large product name | Decide release or stop | You only keep a nice picture |
Hand it to the next shift
- Note the screen angle and the screen ruling of each color.
- Write whether it landed on the barcode or the large product name.
- Use the name on the name list. Do not invent another word.
