Think Ahead, Treat it Right

Over/Undertreating

When a corona treating system transfers too much or too little energy to a substrate, a host of problems can occur. “Attempting to obtain satisfactory printing results on undertreated materials can result in the use of excessive amounts of ink in an effort to try to make up for the inadequate treatment level, and doing so can have its own set of problems,” says Bruce Stobbe, president of Corotec Corporation. “Overtreatment can result in damage to the material itself, as well as problems with blocking of the material.”
