Abstract

Systems and methods for curing inks with radiation. An apparatus includes a housing that includes a pair of reflectors and/or two separate lamps of different power that direct ultraviolet radiation onto the inks being cured. The pre-cure reflector only reflects a portion of the radiation such that the inks are not fully cured. The pre-cure reflector causes the inks to change or thicken slightly such that they do not move on the media or merge with other inks while still retaining a liquid or wet nature. All colors of ink can then be placed in a single layer before the cure reflector fully cures the UV inks by reflecting sufficient UV radiation onto the single layer of UV ink.
