Methods for aggregating resources enhance the export or import of printing resources within a printing system. A resource is selected for a paper. The resource can be a paper catalog entry, a calibration, an ICC profile, or a spot color associated with a paper. One or more calibrations associated with the resource are determined. Peer calibration groups are aggregated based on calibrations sharing the same calibration source data. The resources and groups are displayed so that an operator selects which resources to export or import within the printing system.

The present application discloses a method for spectral prediction and closed-loop feedback wide-width corrugated box extended gamut flexographic pre-printing, belonging to the field of packaging engineering and printing technology. The method comprises: establishing a dot gain mapping function based on the Yule-Nielsen correction model by testing the roughness, ink absorption and surface energy of the corrugated paper; printing a CMYKOGV seven-color characteristic color card to generate an adaptive ICC profile; using the CIEDE2000 color difference formula and constant hue angle mapping algorithm for gamut compression and color separation; selecting a low-hardness flat-top dot flexographic plate and configuring a anisotropic screen roller; introducing the Walker-Fetsko rheological ink transfer equation during printing, combining with real-time feedback of an online spectrophotometer to dynamically adjust the printing pressure and ink viscosity, and realizing closed-loop compensation. The present application realizes high-precision simulation of more than 90% of the PANTONE spot color library, completely gets rid of the dependence on spot colors, significantly improves the color stability and production efficiency of wide-width flexographic printing, and is suitable for extended gamut pre-printing production of high-quality corrugated boxes.

The present invention discloses a color correction method for ceramic printing, which comprises the following steps: (1) Collecting the chromaticity values of the designed printing pictures; (2) Photographing the printed tiles; (3) Collecting the chromaticity values of the photographed pictures; (4) Calculating the color difference between the chromaticity values of the photographed pictures and the background; (5) Calculating the adjustment value of each color block; (6) Recalculating the chromaticity values of each color block of the output file; (7) Regenerating the output file in the Lab color model; (8) Outputting the ICC profile. The beneficial effects of the present invention are as follows: The present invention collects the color of the ceramic surface, compares it with the designed background color, corrects the color of the designed pattern file in units of color blocks, and finally outputs the corrected ICC profile for actual production, enabling high fineness and high color reproducibility after the printed patterns are overprinted.

To suppress degradation of granularity of a printed image, as compared with the case where determination is made of the color material amount of the color material of basic and special colors corresponding to a color value uniformly irrespective of the color value which is going to be converted, when generating profile data for a printing device using the color material of a special color other than the basic CMYK colors.SOLUTION: When the Lab value which is going to be converted is outside of a color gamut expressible by basic CMYK colors and inside of a color gamut expressible by a special color P and the CMYK colors when generating an ICC profile for converting an input color value to the toner amount used for printing, an ICC profile generation unit 32 generates an ICC profile in which the toner amount of each of the CMYKP colors is determined so that the toner amount of K toner becomes zero.SELECTED DRAWING: Figure 5

An example method of video decoding includes receiving a video bitstream comprising a set of pictures, the video bitstream corresponding to a source device. The method also includes identifying color profile metadata for the source device based on a supplementary enhancement information (SEI) message for the video bitstream, and reconstructing the set of pictures using information from the video bitstream. The method further includes causing the set of pictures to be presented at an output device using color characteristics from the color profile metadata.

The present invention discloses an RFID tag printing management method and system. Color comparison and correction are performed using a standard color card and an ICC profile to ensure that the printed color is consistent with the design draft, thereby improving color accuracy. Through initial printing and initial curing, as well as secondary printing and secondary curing, the line width is precisely controlled by laser etching to ensure the stability and integrity of the ink layer, avoid problems such as ink layer adhesion or bubble generation, ensure that the RFID tag line meets design requirements, and improve printing accuracy.

A desktop monitor calibration system uses a smartphone's camera as a color measurement device for a computer's desktop monitor via a network connection between the smartphone and the computer. The system can be configured to leverage a determined metamerism correction profile between individual displays (e.g. brand and model or backlight technology) and individual camera sensors (e.g. device brand and model, or image capture device technology, or brand and model). The metamerism correction profile for each combination of display and camera can be determined by testing and addresses metameric failure for the particular combination. For each calibration instance, the display and camera sensor are each identified, an associated metamerism correction profile is then retrieved from a metamerism correction matrix (MCM), and the metamerism correction profile is used to account for the particular combination of the camera and display when creating an ICC profile for installation on the display's computer.
