  • TONER COMPOSITIONS
    Publication number: 20100297546
    Abstract: Toner particles are provided which may, in embodiments, include a core and a shell. In embodiments, charge control agents may be co-emulsified with a resin utilized to form a shell. The shell may prevent a crystalline resin in the core from migrating to the toner surface. Inclusion of the charge control agent in the shell itself may provide the resulting toner particles with desirable charge characteristics and sensitivity to relative humidity.

  • PRINTING SYSTEM WITH TONER BLEND
    Publication number: 20100092215
    Abstract: An improved electrostatic printing method includes printing a first marking material, such as a fully colorized toner, and also printing a second marking material on the same area of the print substrate. The second marking material is a mixture of two toners, where at least one of the two toners has a lower color strength than the first marking material. The second marking material has the same hue as the first marking material, and the ratio of toners in the mixture is such that the second marking material has a color strength matching that of an undesirable optical density printing rage of the first marking material.
