Abstract
The present invention describes an apparatus for recording a gradient image on transparent media comprising: at least one solid phase change ink; a solid null image element; a heating system capable of melting the solid phase change ink to form a molten phase change ink and capable of melting the solid null image element to form a molten null image element; a printing head capable of receiving the molten phase change ink and the molten null image element and depositing them in an imagewise pattern onto a transfer surface; a transfer surface capable of receiving the imagewise pattern; a cooling mechanism for cooling the molten phase change ink and the molten null image element in the imagewise pattern to form a malleable phase change ink and a malleable null image element in the imagewise pattern on the transfer surface; a media; a transfer mechanism capable of transferring said malleable phase change ink and said malleable null image element in said imagewise pattern on said transfer surface to said media.
