1. A method for selecting a printing device for printing a proof, the method comprising: providing a production printer and a plurality of proof printers; computing a native color gamut by using a spectral data application, the gamut covered by the production printer and the plurality of proof printers, and including gamut information processed by a process manager, where the process manager is configured to operate based on one or more preset standards or preset rules; calculating a gamut intersection volume between the production printer and the plurality of proof printers via the spectral data application, wherein the spectral data application receives spectral data and converts the spectral data into color space data to specify an amount of each wavelength that a sample reflects; comparing the gamut intersection volume between the production printer and the plurality of proof printers; assigning a rating related to the plurality of proof printers, the rating configured to provide data pertaining to the gamut intersection volume difference between each of the plurality of proof printers and the production printer, wherein said rating use weighting factors for a different region, a different section of color space, and a hue volume; and allowing a user to search and select one or more gamuts for each assigned rating, the one or more gamuts provided by the process manager or the plurality of proof printers.
