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.

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.

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.
