Context
4,000 100 ml printed folding have already been printed. Their design is compliant with the product, and the packaging is ready to be used for filling.
The only issue: the already printed EAN code needs to be replaced.
The challenge is that the existing barcode is printed on a pink background. To replace it cleanly, the existing barcode must first be completely covered before printing the new one.
The covering block must also be slightly larger than the existing area to ensure that the old barcode is fully covered.
