    摘要: A method for decoding data that has been encoded in a monochrome medium utilizing the capability of the medium for grayscale resolution. A document is processed to provide an image in electronic format, in which each pixel has an assigned data value with a given bit depth. A mapping operation is performed for generating a monochrome data word (120), preferably having a reduced bit depth. The monochrome data word (120) can be used to encode multiple data fields (114, 116, 118). A printer (92) then produces a preserved document record (90) in which the appropriate monochrome data word (120) determines the grayscale value for each pixel. To decode the stored data, a scanner (86) is employed to obtain the grayscale value from the preserved document record (90). For each pixel, the grayscale value is then decomposed into multiple data fields (114, 116, 118), which can then be decoded to provide the information that was originally encoded.

    摘要: A method and apparatus for printing multiple simultaneous images onto a photosensitive media comprises the steps of imaging light from a light source through an optics assembly (75) to a polarization beamsplitter (80). The polarization beamsplitter (80) produces light having a first polarized state and light having a second polarized state. The first polarized light is directed to a first spatial light modulator (90). The first spatial light modulator is addressed with a first signal to create a first modulated light beam, which is imaged through a print lens assembly onto the photosensitive media. A second polarized light is directed to a second spatial light modulator (95). The second spatial light modulator is addressed with a second signal to create a second modulated light beam, which is imaged through the print lens onto the photosensitive media. The first modulated light beam and the second modulated light beam create at least two simultaneous images on the photosensitive media.

    摘要: A printer (100) able to print in a plurality of output formats depending on width of media (160) loaded in the printer (100) is disclosed. The printer (100) provides high resolution and grayscale imaging capability for monochromatic applications. Illumination optics (11) receive a source light beam, from one or more LEDs, uniformize and polarize the beam and direct the beam through a polarization beamsplitter (50). The polarization beamsplitter (50) directs one polarization state of light to one or more LCD spatial light modulators (52), which modulate the polarization of the polarized beam to provide output exposure energy suitable for image marking on media (160). An optional sensor (234) allows printer (100) to automatically detect the width of a given type of media (160) in order to select from a set of compatible output format. Multiple segments of media (160) at the image plane (150) simultaneously.

    摘要: An improvement for non-uniformity correction in a printing apparatus (10) wherein an image forming assembly (22) forms an image using a plurality of exposure elements, and the amount of exposure energy at each individual exposure element is capable of being varied. A test print (50) is generated, having a series of test patches or zones with predetermined density levels. A scanner (40) scans the test print (50) to obtain density value readings within each test density zone (52) for each pixel that corresponds to each exposure element. Density value readings are averaged. Then, difference in measurement from this average is used to compute a correction factor for each individual exposure element. An image data manager (12) conditions the input data by this correction factor, then sends the conditioned image data to the image forming assembly (22) for printing.
