Color Space, Computer Color Matching Technology.

The ink maker and printer are regularly involved in matching color for packaging and publications. Color Space Technology can map the color space available when using a given line of pigment colors. Computer color matching does the same job the formulator has been doing in the laboratory, but much faster with less need to make inks. The technology will be useful to: (a) define color limits of pigments new used; (b) design an optimum pigment selection to produce the maximum amount of color space and determine if the color to be matched falls within the color space available; (c) determine if deletion or addition of a pigment color either reduces or expands color space; (d) determine the effect of substituting one pigment for another. Although the technique has been developed in working with paint systems, it may be applicable in graphic arts as an aid to either ink makers or printers where color matching problems exist. It should also help in optimizing the number and type pigment colors inventoried.
