Vetaphone - Corona & Plasma for Narrow Web

The Corona surface treatment is essential in label printing. When the label is made from plastic substrate the ink tends to become blemished due to its inability to bond to the plastic. This problem occurs because the surface energy of the plastic is insufficient to permit a proper bond. A quality Corona treatment is necessary to ensure the perfect label print quality we all want to see when looking at products at the end of the production line. Therefore, our Corona-Plus systems are not only designed for our customers in narrow web printing, but also for our customers’ customers, as our Corona- Plus systems help you obtain a flawless and long-lasting quality print.

Often, our customers discover that batches of incoming material have low dyne level (surface adhesion) or that the dyne level of the material on stock has decreased due to heat or humidity. Due to the low dyne level the narrow printing press cannot run at full speed.

As a consequence, the Vetaphone Corona systems are used for boosting already treated materials to create high adhesion ability.

A common problem in the narrow web industry is the necessity for using top coated materials which have been chemically altered in order to obtain a high surface adhesion for inks. The top coated materials are more expesive to purchase than regular materials.
