Corona Treater Machine for Printing

A corona treater is an essential component in modern label and sticker printing production, delivering improved print performance on a wide range of synthetic, acrylic, vinyl materials. This electronic treatment system uses controlled high voltage discharge to modify the surface characteristics of a material before it enters the printing process, creating optimal conditions for ink adhesion.

Many films, plastics, and specialty substrates used in label manufacturing have low surface energy, making it difficult for ink to bond correctly. The corona treater increases surface energy and improves the material properties, allowing inks and coatings to spread evenly and adhere more effectively. This results in sharper graphics, stronger colour density, reduced print defects, and enhanced durability.

For UV printing, a corona treater helps achieve consistent image quality while reducing the risk of ink rejection, pinholes, and poor coverage. Integrated into a printing machine, it supports reliable production of high quality labels and stickers while expanding the range of printable materials available to converters and manufacturers.
