When the edge scums on a pharmaceutical label, what do you move first
When the edge scums on a pharmaceutical label, check impression and water. Do not add ink across the whole plate. Change only this one thing. Look again in the same place after you change it. The dirt is only a ring around the image edge. The middle of the blank is clean.

Move one thing first
Stop if the dirty edge enters the small type or a barcode. If it has already hit the batch code, the expiry date, or a barcode, stop first, then adjust. Do not try it while the press keeps running. Scumming spreads into the middle of the blank. It does not stay only on the edge.

| It has already landed on the batch code, the expiry date, or a barcode | Try it while the job keeps running | Scrap keeps going |
| Log which colour's impression and water feed. | Only say you already adjusted it | The next shift cannot pick it up |
Leave this behind
