Baked version to dirty tips

When printing a large number of printed products, the ps version must be baked. After the printing plate is printed on the machine, the operator finds that the printed product has just been printed. Since the printing plate is baked, there are too many dirty tracks, so it cannot be handled with hard objects such as blades, and it cannot be discarded. It can only be removed by rubbing.

First wipe with a cloth dampening powder a few times, still appear after the boot. After wiping the cloth with water and dampening powder, it could not be removed. After cleaning it with your fingers instead of the cloth, it was still dirty.

How can we remove it without scrapping the plate?

The team personnel estimate that it is likely that the printing process was not handled properly. Then can we use the revised paste to remove it? When we use the cloth to wipe the number with the revised paste, the stain on the plate is still visible, and the dirt on the printed product disappears after the boot. Suggestion: In such a situation, before this version is used, the method is used to wipe the whole page, and the chance of contamination will be greatly reduced.
