Abstract: A printing apparatus (100) for printing digital images onto a photosensitive medium (140) employing, for exposure energy, a light source (20) that uses various arrays of LEDs (32). The printing apparatus (100) may form the print image using sequential modulation, one color at a time, or by applying all colors simultaneously. Arrangements of discrete LEDs (32) may include high-intensity devices configured with collector cones (41) arranged as a multicone structure (141), with parabolic reflectors (65), or collimating lenses (36). Large area LEDs (46) may alternately be used, arranged on an angled mounting surface (64), for example.

Abstract: A method of printing a plurality of image frames from a digital image file of a motion picture sequence to a photosensitive medium comprising one or more light-sensitive recording layers, comprising the steps of: a) providing at least one two-dimensional OLED modulator, wherein the OLED modulator comprises an array of independently activatable microcavity OLED elements, each OLED element defining an optical cavity for reducing the angle of emission of light from the OLED element and tuning the light output of the OLED element to a limited spectral band emmitance range wavelength matched to the spectral sensitivity of a light-sensitive recording layer of the photosensitive medium; b) responding to the digital image file to independently activate the OLED elements in the two-dimensional OLED modulator to provide visual images corresponding to each frame of the motion picture sequence; and c) moving the photosensitive medium past the visual images to illuminate different portions the medium to record the motion

Abstract: A high-speed writer suitable for continuous writing of data onto a photosensitive medium is disclosed. The system includes an illumination source having a plurality of individual colors. An illumination optical element distributes individual color onto distinct areas of the high-speed area array modulator, wherein each distinct area is proportionally related to the photosensitive medium's sensitivity to a corresponding color. A high-speed area array modulator rapidly modulates the plurality of individual colors in correspondence to the data on a pixel-by-pixel basis. An output optical element directs the modulated color light from the high-speed modulator onto the photosensitive medium; and a frame synchronization shifter synchronizes movement of the data to contiguous areas of the high-speed area array to the photosensitive medium while it is in continuous motion.
