First and foremost, UV curable offset inks are regarded as a particularly environmentally friendly printing system compared to conventional oxidative polymerization drying offset inks.
They are characterized primarily by the fact that they do not include VOC (volatile organic compounds). Regular ink involves dissolving solids or high-viscosity resin in organic solvents, which are then released through volatile evaporation during printing. This gives rise to various issues that need to be addressed, including operational safety during the printing process and health hazards from residual solvents on printed matter. UV curable inks on the other hand use low-molecular organic compounds that produce photo-polymerization reactions under ultraviolet light as solvents, all of which are cured through polymerization during the printing and drying process, eliminating volatile evaporation of solvents.
