When plate bounce on a corrugated preprint means a stop
Plate bounce on a corrugated preprint means a stop when that streak crosses the main image. If it hits the barcode or the large product name, this sheet cannot go out. It is one streak in a fixed place after the gap or the gripper.

Look first at whether it hits a critical spot
It is one streak in a fixed place after the gap or the gripper. Gear marks come as many lines at the tooth pitch; bounce is often just one. On a corrugated preprint, the critical spots are the barcode or the large product name. When the decoration has no spot chart, do not invent a millimetre number on the spot.
What to compare
| What you see | How to call it | Do not |
|---|---|---|
| One streak in a fixed place after the gap or the gripper. | Stop if this streak crosses the main image. | Add ink or pressure just because you can see it |
| Lands on the barcode or the large product name | This sheet cannot go out | Wait for the next process to find it |
| Only on the decoration, and there is no spot chart | Keep a sample and confirm | Write your own millimetres |
Do this first on this round
- Confirm it is plate bounce: one streak in a fixed place after the gap or the gripper.
- Ease the bearer shock or check the gap. Do not change the ink first.
- Note the around-the-cylinder position and which colour.
