Is it Time to Bump the Bump Treating

Whether or not re-treating substrates is a necessity for all printing methods and ink types has long been debated, said Mark Plantier, vice president of marketing, Enercon Industries. It is an accepted fact that bump treatment is required for all water-based and UV printing applications. Traditional thinking also dictates that surface treating is not possible and not required for solvent applications, but a closer look at the printing process reveals otherwise, he said.
