Abstract: Custom color control techniques are extended by using a high and a low pigment loaded toner for each color of the primary colors in the printing system. In one application, a large gamut of colors and fine control of color is accomplished by using a minimum number of colored pigments with each color incorporated into both high and low pigment loaded toners. Another application of the high/low pigment loaded toners is the ability to increase the developed mass per unit area (DMA) for rough papers without increasing pigment mass per unit area (PMA) by either mixing high and low pigment-loaded toners or by mixing a high pigment-loaded toner with an unpigmented toner to obtain the desired custom color. A novel sensor which senses fluorescent molecules in toner particles provides a color independent measure of total toner solids.
