Keeping up Appearances

Rea also reminds printers about the printing surface dyne level—it should be relatively high compared to the liquid tension of the UV/EB product to avoid beading up or reticulating off the substrate's surface. One not-so-obvious cause of low-energy surfaces could be migratory materials found in substrates, inks, or base coating layers, which move to the surface after exposure to heat or pressure. Vendor consultation, as always, is important to avoid/resolve such challenges.
