Flexographic ink systems cover a wide gamut - solvent-based, water-based, and ultraviolet-light cured. These system categories will include solvents, colorants, resins, additives, oligomers, monomers and other unique compounds. Each ink component influences the viscosity and surface energy of the ink and its relative adhesion to various substrates at different press speeds. Surface energy is the common denominator between ink and substrate, quantifying the disruption of intermolecular bonds that occurs when a surface is created and interfaced with. The surface energy is the excess energy at the surface of a material compared to the bulk, and must be critically modified to optimize adhesion. Low viscosity polyester acrylate oligomers developed for a flexographic ink system with high TiO2 loads will wet differently to different substrate surfaces. This presentation will define the ideal surface energy calibrations between the different flexo ink systems and various substrates.
