SPECTRAL PRINT CONTROL BASED ON SPECIFIC SPECTRAL RANGES OF COLORANTS

摘要

Certain methods and systems are described that allow the spectral control of a print output. A plurality of colorants are used where one or more colorants contain nanoparticles. Each colorants has a specified spectral range corresponding to the constituent nanoparticles. To print with these colorants a spectral separation may be used that maps an input color with associated spectral information or direct spectral information to print control data, the print control data having defined values for depositions with each combination of the colorants. The spectral separation may be constructed by characterizing a set of spectral Neugebauer primaries for the plurality of colorants.

1. A method comprising:
mapping an input color with associated spectral information to print control data using a spectral separation, the print control data having defined values for depositions with each combination of a plurality of colorants, each colorant having a specified spectral range, wherein the print control data is usable to produce a print output using the plurality of colorants, and wherein a set of spectral ranges for the plurality of colorants provide a distribution of at least one peak emission value and full-width at half-maximum value over a given spectral range.
