摘要:
An ink composition has controlled conductivity, and a digital printing system and a method of printing an ink employ an offset inkjet printing platform. The ink composition includes pigment particles dispersed in an oil-based dielectric carrier fluid with an oil-soluble dispersant. A concentration of dispersant is a fraction of a concentration of the pigment particles sufficient to render an electrical conductivity of the ink composition less than 100 pico Siemens per centimeter (pS/cm). The printing system includes an ink having an electrical conductivity less than or equal to about 300 pS/cm, an inkjet print head, a transfer medium, a developer, a remover and an image transferer. In the method of printing, the ink is nonelectrostatically jetted to the transfer medium, and developed into a fixed image. A portion of a supernatant is removed from the fixed image, and the fixed image is transferred to a media substrate.
