Abstract
The present invention is directed to a method of utilizing a digital micromirror device (DMD) to spectrally matching a standard or device-independent color. DMD can be fitted on an integrated chip and can provide more than one thousand (1,000) color primary channels for low metameric color matching producing a spectrally matched batch color. This represents a two orders of magnitude improvement in color matching.
Claims25
A method for spectrally matching a standard color, wherein the standard color is device-independent, comprising the steps of
- a. obtaining a spectral power distribution (SPD) curve of the standard color;
- b. providing a digital micromirror device (DMD) having “n” rows and “m” columns of micromirrors;
- c. projecting a substantially full visible spectrum of electromagnetic radiation on to the DMD;
- and
- d. modulating said substantially full visible spectrum of electromagnetic radiation to create a modulated visible electromagnetic radiation with the DMD, wherein said modulated radiation spectrally matches the SPD of the standard color.
