摘要： In preparation for rendering respective portions of a document via a respective plurality of engines, objects within the document are identified and characterized. A determination is made as to whether gamut variations between the engines might result in objectionable variations in the appearance of rendered versions of identified objects having similar characteristics. For those objects within the document for which the determination is made that variations might be objectionable, a target gamut is selected to be an intersection gamut of the engines to be used to render the document. For those objects within the document for which the determination is made that variations would be unobjectionable, the target gamut is selected to be that of selected individual engines. A system for selecting target gamuts for objects within a document can include an object identifier, a characteristic identifier and a gamut selector.

摘要： At least sequential current and subsequent sheets of a print job are received in a document processing system. Each sheet includes a front image and a back image. The received sheets are scheduled to be printed with at least one of a first and a second sequence by at least one of a first and a second marking engine based on a comparison of the image content in corresponding selected portions of each front and back image.

摘要： Spatially dependent colorant interaction effects are identified and isolated from other aspects of spatially dependent colorant appearance nonuniformities. A decorrelating function for compensating for the identified spatially dependent colorant interaction effects is determined. Spatially dependent single colorant compensating functions for compensating for the other aspects of the spatially dependent colorant appearance nonuniformities may also be determined. Image data is processed through the decorrelating function, thereby generating colorant values that are compensated for spatially dependent colorant interaction effects. Optionally, image data is also processed through the spatially dependent single colorant compensating functions, thereby generating colorant values that are compensated for both aspects of colorant appearance nonuniformities. The two kinds of compensating functions may be determined, calibrated and/or stored at different spatial and temporal frequencies or resolutions. One or both of the compensating functions may be employed to maintain consistency across a plurality of rendering devices (e.g., marking engines).

摘要： The present disclosure provides processes for producing images of excellent color fidelity when incorporating a magenta toner with a lower colorant loading in addition to a first magenta toner. In embodiments, the magenta pigmented particles may be magenta emulsion aggregation toners. In accordance with the present disclosure, a pair of magenta toners are matched in color, wherein the color of a first magenta toner printed at a predetermined halftone area coverage on a substrate substantially matches the color of the solid (100%) printed patch of the second magenta toner, which is lighter than the first magenta toner, thus avoiding a visible hue shift on the print that would otherwise be objectionable. In embodiments, the light magenta toner is color matched by adding a hue-adjusting colorant or combination of colorants which absorb wavelengths of light between 400 and 500 nanometers, and optionally adding a shade-adjusting colorant or combination of colorants which absorb wavelengths of light between 600 and 700 nanometers.

摘要： The present invention is directed to a system and method for test target selection in conjunction with dynamic test pattern generation. In the invention, a test pattern page(s) is composed using an optimal set of test targets, which can be accommodated or adjusted to fit within size constraints of the test pattern. The method of the present invention makes use of layout optimization to ensure that related and optimized test targets are accommodated on a single test pattern. For example, it may be preferable to “squeeze in” a smaller-than-normal uniform area target, rather than not to print it at all during a test.

摘要： This invention relates to a method and apparatus for implementing a trapping operation on a digital image during image processing. Some embodiments of the present invention provide an intelligent trapping process to compensate for registration errors or halo effect errors by an imaging device. At various times, a set of customized trapping parameters may be determined for the device based on its actual or estimated performance. The imaging device may be checked automatically on a periodic basis, in response to an event, or upon request. The trapping parameters may be unidirectional and may vary temporally or spatially. The imaging device can then print images based on its customized set of trapping parameters.

摘要： An ink key simulator for image forming devices may simulate the effect of ink key adjustments in offset presses. The image adjustment may be made in response to activation of a simulated ink key, for example, by adjusting the pixel values of the stored data and/or by adjusting imaging light source intensity within a given region of the image. Using the ink key simulator, adjustments to image quality from printers may be made on-the-fly using an interface which is familiar to the operators of offset presses.
