What should I do if there is whiteness in carton printing?

In the full-page printing of the upper printing type, there will always be paper scraps sticking to the plate, resulting in leakage. The customer has strict requirements. One mark cannot exceed three leakage spots, and one leakage spot cannot exceed 3mm. It is not ideal to remove dandruff with kraft glue.
