Abstract
The present disclosure provides processes for producing images of excellent color fidelity when incorporating a magenta toner with a lower colorant loading in addition to a first magenta toner. In embodiments, the magenta pigmented particles may be magenta emulsion aggregation toners. In accordance with the present disclosure, a pair of magenta toners are matched in color, wherein the color of a first magenta toner printed at a predetermined halftone area coverage on a substrate substantially matches the color of the solid (100%) printed patch of the second magenta toner, which is lighter than the first magenta toner, thus avoiding a visible hue shift on the print that would otherwise be objectionable. In embodiments, the light magenta toner is color matched by adding a hue-adjusting colorant or combination of colorants which absorb wavelengths of light between 400 and 500 nanometers, and optionally adding a shade-adjusting colorant or combination of colorants which absorb wavelengths of light between 600 and 700 nanometers.
