  • Patent number: 6618066
    Abstract: An image is printed on a substrate by means of a computer driven ink jet printer using heat activated dye, without activating the dye during the process of printing onto the substrate. The individual solid dye particles are present in a liquid ink, and are stabilized in the ink by an emulsifying enforcing agent that emulsifies the solid dye particles within the ink. The dye is subsequently activated by applying sufficient heat and pressure to the substrate to activate the dye and permanently bond the image to a final substrate. The resulting permanent image is resistant to laundering.

  • Publication number: 20030156181
    Abstract: A technique for optimizing or enhancing color images. Embodiments are disclosed for creating an enhanced color image, including the enhancement of perceived color uniformity. In a “dot-on-dot” registration scheme for producing color images, the dots need to be precisely superimposed on each other to provide optimum or enhanced images. The dot-on-dot registration produced by a single head thermal printer is generally acceptable, but a single head machine is very slow because multiple passes (reciprocation) are required to lay down multiple colors of dots. In a much faster multi-head or tandem thermal imaging system a serious problem of dot misalignment may cause moire patterns or other visual artifacts in the color images produced by dot patterns. A solution to this problem is disclosed herein which intentionally misregisters superimposed dots in a novel and particular manner to achieve image optimization.

  • Patent number: 6587133
    Abstract: For in-line printing and processing of successive portions of a band material, the portions are each printed in a printing position (5; 157) and processed in a processing position (36; 43), both along that transport path (1; 101). The band material is advanced at least once over a predetermined distance along the transport path (1; 101) for transferring portions of the band material from the printing position (5) or the processing position, to the processing position (36; 43) or, respectively, the printing position (157). Since the printing is carried out incrementally in accordance with the incremental formation of the printing, changes in the printing from portion to portion can be implemented easily. Since each printed portion is advanced over a remaining portion of the predetermined distance after printing, it is assured in a simple manner that the printings are accurately aligned in transport direction for processing to be performed.

    Abstract: To calibrate a printer that prints a full-color image on a recording paper in a color frame sequential fashion, a gray pattern is printed by the printer onto a recording paper, to three color densities of the gray pattern. A recording energy correction amount for magenta is determined based on a difference between the measured magenta density and a set magenta density. Then density variations in yellow and cyan from their set values are estimated that would be resulted from the recording energy correction for magenta. Then recording energy correction amounts for yellow and cyan that reduce the estimated density variations are calculated. Thereafter, density variations in magenta and cyan that would be resulted from the recording energy correction for yellow are estimated, and recording energy correction amounts for magenta and cyan that reduce the estimated density variations are calculated.

  • Patent number: 6204873
    Abstract: A color conversion adjustment method is provided which enables correct judgment on a fine gray balance. In a process of adjusting or confirming gray correction conversion for correcting a gray balance, a plurality of color patches, whose gray balances are varied discretely, are lined up, and a gray correction chart, whose background portion other than the color patches is outputted at a black color of a predetermined density, is outputted. The black color of the background portion is a standard for judging the color balance. Because the color patches and the black color are printed on the same paper, there is no deterioration in the gray balance due to differences in papers, and accordingly, fine gray balance can be judged more accurately.
