    摘要: Measurement devices, systems, and methods to measure a high field conductivity of a fluid are provided herein. The measurement device includes a fluid cell, a pair of electrodes, a voltage switch, and a measurement unit. The fluid cell is on an inclined plane to receive the fluid. The pair of electrodes are connected to the fluid cell. The pair of electrodes are spaced apart from one another to receive the fluid therebetween and positioned parallel to one another to pass an electrical current therethrough. The power unit provides a high voltage power supply to one electrode of the pair of electrodes. The measurement unit measures the electrical current that passes between the pair of electrodes through the fluid.

    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.

    摘要: Hard imaging devices and methods are described. According to one arrangement, a hard imaging device includes a media transport system configured to move media along a media path and a print device adjacent to the media path and configured to eject a plurality of droplets of a liquid marking agent in a direction towards the media moving along the media path to form hard images using the media. The ejection of the droplets of the liquid marking agent by the print device creates satellites of the liquid marking agent suspended in air in a region adjacent to the print device and the media. The device also includes a satellite removal system in one arrangement to remove the satellites from the air in the region adjacent to the print device and the media.
