3.Rubber roll has been used long ageing, again of together with chemical erode, cause sodden glue to drop " broken bits " , such rubber roll had better not reuse, affect badly otherwise imprint quality quantity.
4.For guarantee against the influence is produced and presswork quality, must have reserve Mo Gun, but also do not store avoid ageing too much. Of rubber roll like depositing environment and mackintosh. Additional, rubber roll should be in in journal flat had worn, and the surface does not want be contacted each other or contact with other goods, lest rubber roll is out of shape.
