Radiation Curing of Printing Inks
The use of radiant energy to dry or assist in the drying of printing inks has been in practice since ancient times when oxidizing ink systems were placed in the sun to speed drying. This original use of radiation curing, ultraviolet (UV) light and radiant heat, to enhance drying has truly only come of age since the late 1960s. In the fall of 1969 the first commercial run of UV curing inks on a folding carton took place on a multicolor sheetfed offset press. Although earlier patents exist, the use of UV light for curing inks was not suitable for commercial exploitation until the chemistry and a suitable power source were developed around this time.
