摘要： A tunable Fabry-Perot filter (8, 118, 218, 318, 418) includes substrates (10, 12) with parallel generally planar facing principal surfaces (14, 16) including spaced apart facing reflective surface regions (20, 22) that are at least partially reflective over a wavelength range and define an optical gap (Gopt) therebetween. At least one substrate of the pair of substrates is light transmissive over the selected wavelength range to enable optical coupling with the optical gap. Electrodes (24, 26) are disposed on the facing principal surfaces of the substrates. The electrodes on the facing principal surfaces of the substrates are define an electrode gap therebetween such that electrical biasing of the electrodes simultaneously modifies the optical and electrode gaps.

摘要： The present disclosure is directed to a system and method to render spatially uniform memory colors when images printed with CMYK primaries are not rendered uniformly due to output device quality errors. The disclosed method uses an array of sensors to scan a test image. Colors of interest are printed at the desired location first and then adjusted (iterated) to achieve a desired output quality. Iterations are carried out on the image on desired memory colors at the spatial resolution available in the measurement system. Colors of pixels are modified based on position where the pixels will be rendered, thereby compensating for any position/process related differences. Also disclosed is a process for incorporating modified memory colors before rendering, and the extension of memory color concepts to adjust colors for the uniform blocks (not edges), with uniformity defined by user definable thresholds.

摘要： Printing occurs when a marking engine deposits ink on a substrate to produce a pattern. The printed pattern can differ from the desired pattern when the marking engine is out of adjustment, the substrate and ink do not interact optimally, or for other reasons. A tone reproduction curve can be used to adjust the pattern or the marking engine so the printed pattern and desired pattern are similar. Another effect of printing is that contours can appear. Contouring can be reduced if a smooth tone reproduction curve is used. Aspects of the embodiments address limitations and flaws in the prior art by using a smoothing parameter and a smoothing matrix to produce TRCs that minimize contours.

摘要： Tone reduction curves are utilized to map an input value to an output value. A tone reduction curve is normally produced by an algorithm that fits a curve to a series of knots. Knots can be determined from calibration data. Printing a calibration patch pattern yields a target patch pattern. The desired reflectances of the calibration patches and the measured reflectances of target patches can be used as calibration data. The series of knots can also include a highlight knot and a shadow knots so that the tone reduction curve functions better in the highlight and shadow regions.

摘要： To generate a reference database for a particular sensor in a multiple LED spectrophotometric system with a reduced number of test measurements taken from training samples, a first set of reflectance reference measurements are generated from a test target on to a reference sensor from a plurality of different LED emissions. A first spectral reconstruction reference matrix is computed comprising an operational characterization of the reference sensor from the first set of reflectance reference measurements. A second set of reflectance reference measurements from the test target is generated from a second subject sensor whose operation is to be personalized by the objective reference database. The second set of reflectance reference measurements are less in number than the first set. A second reconstruction matrix is computed comprising an operational characterization of the subject sensor from the second set of measurements. The second reconstruction matrix is adjusted by relating the second set of reflectance measurements to a set of corresponding reflectance measurements of the reference sensor, whereby the adjusting of the second matrix comprises computing an optimal solution spectral reconstruction matrix for the second sensor. The reference database is generated from the optimal solution spectral reconstruction matrix.

摘要： What is disclosed is a method for maintaining consistent color output across printers even when the inline sensors have differences in accuracy due to various technical and environmental factors. A spectrophotometer is used to measure the color quality of printed references. Adjustments are then iteratively made until reference charts of desired color quality are obtained. The printed reference allows one to achieve relatively high system performance by removing sensor inaccuracies. Using the printed reference measured by the inline sensor control systems of each machine are calibrated. At customer sites and at suitable intervals, a reference document can be read using the inline sensor on a reference machine and any differences from expected values can be calibrated out. The present method is also applicable to other color management functions such as memory color and automatic profile generations using inline/offline sensors and can be used for determining reference values while calibrating control systems of printers over a wide range of applications.

摘要： Multiple input patches are received on an output media, which patches are characterized by print density representing a document processing system's response to different input grayscale values over a potential response space. Values associated with the print density of each input grayscale value are measured. Reference Engine Response Curves are determined from the measured print density values and input gray scale values. A variance data representative of a difference between each measured print density value and a respective reference Engine Response Curve is determined. The variance data is transformed into individual components. Based at least on one selected individual component, a set of calibration compensating Tone Reproduction Curves is determined. The determined calibration compensating Tone Reproduction Curves are applied to input grayscale values.
