Color image forming method and color image forming device

The present invention relates to a color image forming device for forming toner images of a plurality of colors on a medium, and is for improving second transfer efficiency from an intermediate transfer body to the medium. The device has image forming units (12-1 to 12-4) for forming the toner images of the plurality of colors on at least one image bearing body (14-1 to 14-4) by a plurality of developing units (22-1 to 22-4) respectively accommodating toner of different colors; an intermediate transfer body (24); primary transfer means (38-1 to 38-4) for primary transferring the toner images of the plurality of colors onto the intermediate transfer body sequentially for the respective colors; and secondary transfer means (45) for secondary transferring the toner images of the plurality of colors on the intermediate transfer body onto the medium. The image forming units form the toner images of the plurality of colors so that the potentials of toner layers transferred onto the intermediate transfer body (24) are progressively lower in the order in which the plurality of colors are transferred. Since the potential of the toner layer directly adhered to the intermediate transfer body is higher, the directly adhered toner layer becomes easier to be secondary-transferred, and thereby, the secondary transfer efficiency is improved and the reproducibility of the secondary color is improved.

Dual complementary two-color optics which enables a user to see true neutral color, with improved shading design and shadow detail

A pair of dual complementary optics having a first lens and a second lens wherein the first lens has a gradient of a multiplicity of bands, the uppermost series of bands having a primary color embedded therein and the lowermost series of bands having a complementary secondary color embedded therein, the second lens having the inverse color embedded therein so that a primary color in the first lens is aligned with a secondary color in the second lens and a secondary color in the first lens is aligned with a primary color in the second lens. The color correction units are created such that the uppermost band has the largest amount of color correction units gradually decreasing to the lowermost band of the same color having the least amount of color correction units and thereafter, the second lower color has the lowest amounts of color correction units in the uppermost band of the secondary color gradually increasing to the greatest amount of color correction units in the secondary color in the lowermost band with the inverse in the second lens so that the lens is darkest on top and on the bottom and is lightest in the middle. Each lens is capable of either transmitting more than fifty percent of visible light in both wavelength ranges 400–550 nm and 550–750 nm or is capable of transmitting less than fifty percent of the visible length in both wavelength ranges 400–500 nm and 550–750 nm.

Very-high-ratio mixed resolution and biphod pens for low-cost fast bidirectional one-pass incremental printing

An incremental printer, such as for example an inker printer, produces very small markings (as for example by firing small ink droplets) preferably in a single-pass print mode for text, as well as image applications if desired, to achieve addressable print resolution at least four times higher in the carriage scan axis than in the media advance axis. More preferably the resolution in the scan axis is at least six times, ideally eight times, higher than that in the media advance axis. A preferred form of the invention uses 96 dots / mm (2400 dpi) resolution in the scan axis, in conjunction with only 12 dots / mm (300 dpi) resolution in the media advance axis, without having to employ any dot-depletion algorithms. In one embodiment, the system provides a single-pass color print mode wherein primary colors are printed with eight color droplets of the same primary color in eight adjacent sub-pixels on the 300x2400 grid, and secondary colors are printed with eight color droplets of different primary colors in eight adjacent subpixels on the same grid. One implementation uses a pen with a single tab-head assembly, with nozzles in plural parallel staggered columns, receiving ink from plural different ink reservoirs. Two such pens provide four inks for color inker printing. Three or more such pens enable a printing system to supply ink of plural dilutions for at least one of the ink colors in the system, and thereby facilitate photographic-quality printing.

Control interface for converting subtractive color input to additive primary color output

A control interface for producing a composite color through the mixing of primary colors selected from a first color spectrum including red, yellow, and blue, resulting in the display of said composite color through a light array containing lights of a second primary color spectrum is disclosed. The user selects a color or colors from the first primary color spectrum, and a circuit and control algorithm controls the relative intensities of the colors comprising the second primary color spectrum, rendering the selected color or a mix of previously selected colors through the light array. Through the selection and graduated combination of the primary colors of the first spectrum, the creation of a wide range of colors in the visual spectrum is obtained for lighted color applications. When the first spectrum comprises the primary colors of red, yellow, and blue, the user is able to use the familiar three-primary, three-secondary color wheel, used in art education and taught in elementary school, for their color combination reference. The color selections from the first spectrum are coded to produce corresponding electrical signals to control the output of the light array to establish the proper mix of colors that displays the selected color.
