Corona Treater for Dry Offset Printing Machine

Corona Treater for Dry Offset Printing Machine

A Corona treater is a device that is commonly used in the printing industry to improve the adhesion of inks and coatings to plastic substrates. In dry offset printing, where the image is transferred from a plate to a rubber blanket and then to the substrate, a Corona treater can be used to improve the adhesion of the ink to the substrate.

To use a Corona treater in a dry offset printing machine, the substrate is first passed under an electrode that is charged with high voltage electricity. This creates a corona discharge, which causes the surface of the substrate to become more receptive to inks and coatings. The substrate is then passed through the printing press where the image is transferred.

There are many different types of Corona treaters available, including bare roll treaters, covered roll treaters, and electrodeless treaters. The choice of treater will depend on the specific requirements of the printing application, as well as the type of substrate being used.

It is important to note that Corona treaters can be dangerous if not used properly. High voltage electricity is involved, and proper safety precautions must be taken to avoid injury or damage to the equipment. It is recommended that only trained professionals operate Corona treaters.
