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