The term color strength is defined as the hue, saturation, and brightness of an ink in the C.I.E. scheme of color specification. With this definition two color strength measuring methods are evaluated on a common basis. A colorimeter is used to read samples produced with varied ink-film thicknesses and varied ratios of white pigment to sample ink. Colorimetric properties are plotted on a U.C.S. diagram with coordinates modified to include the C.I.E. brightness factor W*. The ink-film thickness method is chosen as the preferred method for determining color strength.
