When a scratch shows on a pharma label, what do you move first
Check the idler rollers and burrs first. Do not adjust the ink. Change only one thing. Write down which idler and the metres.
When a scratch shows on a pharma label, check the idler rollers and burrs first. Do not adjust the ink. Change only this one thing, then look again in the same place. A fine bright line in the web direction, where the ink film is scraped open.
Move one thing first
Stop if it cuts the image or the seal layer. On a pharma label, if it already hits the lot number, the expiry, or the barcode, stop before you adjust. Do not try it while the press is running. A doctor-blade line is too much ink or too little. The sheet surface is not necessarily cut.
Order
| Do first | Not yet | Why |
|---|---|---|
| Check the idler rollers and burrs first. Do not adjust the ink. | Change ink, impression, and speed together | Change three things and you will not know which one worked |
| It already landed on the lot number, the expiry, or the barcode | Try it while production is running | Scrap keeps moving |
| Write down which idler and the metres. | Only say that you already adjusted it | The next shift cannot pick it up |
Leave this when you are done
- Check the idler rollers and burrs first. Do not adjust the ink.
- In the same place, confirm whether the scratch has eased.
- Write down which idler and the metres.
