Abstract: A method for correcting for hue shifts includes parameterizing the conversion of long-medium-short (LMS) spectral sensitivities of the human eye to a human observer function, and applying a non-linear transformation between the LMS and human observer function in order to correct for the hue shifts. A system for correcting for hue shifts is also provided. The system includes a controller for parameterizing the conversion of LMS spectral sensitivities of the human eye to a human observer function and applying a non-linear transformation between the LMS and human observer function in order to correct for the hue shifts in the image. The system can also include an output device for presenting the hue corrected image.

Abstract: Techniques for producing a color profile that characterize the color response of a color imaging device involve the use of a gray backing material. The gray backing material is placed behind a sheet of output media during measurement of color elements in a reference image formed on the output media. The gray backing material may be particularly useful for output media that is very thin or slightly transparent. In particular, unlike black or white backing materials, the gray backing material produces very little visual interference when the reference image is reproduced, providing a close visual match. Use of a gray backing material can support generation of more accurate color profiles.

Abstract: An apparatus and method for recalibrating a multi-color imaging system are provided. The multi-color imaging system is capable of applying different colorants to a substrate based on a plurality of input color values. The input color values control amounts of the colorants to be applied to the substrate by the imaging system. A subset of the input color values is selected and used to control the imaging system to apply one or more of the different colorants to the substrate, thereby forming a plurality of different color patches on the substrate. The subset of input color values is selected such that one or more of the different color patches is formed by application of a combination of at least two of the different colorants to the substrate. Color values are measured for each of the different color patches, and compared to reference color values, representing a calibrated condition of the imaging system. An error value is calculated. The error value represents a deviation of the measured color values from the reference color values. The input color values for each colorant then are independently adjusted to reduce the error value to a predetermined degree.

Abstract: Modification of color values in a page description file can be carried out by converting implicit color commands within the page description file to explicit color commands. The color values specified by the explicit color commands within the page description file then are adjusted to calibrate an output device for enhanced color fidelity. Implicit color commands specify color values indirectly, for example, by defining color as a function of other graphic information and color reference values. Consequently, color modification prior to RIP conversion generally is difficult. Conversion and modification of explicit color values provides a higher degree of color conversion accuracy without the need for RIP conversion of the page description file.
Abstract translation: 通过将页面描述文件中的隐含颜色命令转换为显式颜色命令，可以对页面描述文件中的颜色值进行修改。 由页面描述文件中的显式颜色命令指定的颜色值被调整以校准输出设备以提高色彩保真度。 隐式颜色命令间接指定颜色值，例如通过将颜色定义为其他图形信息和颜色参考值的函数。 因此，在RIP转换之前的颜色修改通常是困难的。 显式颜色值的转换和修改提供了更高程度的颜色转换精度，而不需要对页面描述文件进行RIP转换。
