Is it Time to Bump the Bump Treating

There are many factors that influence how long a material holds a dyne level. Taking everything into perspective, if a printer is printing a range of materials for a range of applications, re-treating substrate surfaces is the key to consistency. "More converters use film from several different suppliers and run several different products on each press," said Chuck Ballard, product manager corona treaters, Pillar Technologies. "Given these variables, the only way to ensure a consistent quality is to bump treat the material."
