Abstract

The present disclosure is drawn to LEP toners, systems, and methods of manufacturing LEP liquid toners. Specifically, a high NVS liquid toner can comprise a ground up admixture of a hydrocarbon carrier fluid, pigment particles, and a polymer paste having an NVS content of about 38 wt % to about 65 wt %. The resultant high NVS liquid toner has an NVS content of about 28 wt % to about 38 wt % and a viscosity of about 3,000 cPs to about 25,000 cPs.
