Abstract:
An apparatus for recording a gradient image on transparent media comprising:at least one solid phase change ink;a solid null image element;a printing head capable of melting said solid phase change ink to form a molten phase change ink and melting said solid null image element to form a molten null image element and depositing drops of said molten phase change ink and drops of said molten null image element in subpixels to form an imagewise pattern wherein said drops of said molten phase change ink are between 10 nanograms and 150 nanograms in mass;a transfer surface capable of receiving said imagewise pattern of said molten phase change ink and said molten null image element from said printing head to form a malleable phase change ink and a malleable null image element in said imagewise pattern on said transfer surface; anda media capable of receiving said malleable phase change ink and said malleable null image element in said imagewise pattern from said transfer surface.
