摘要:
Systems and associated methods of printing using ink-jet technology and offset printing capabilities are provided. The method can comprise jetting an ink onto a printing blanket, where the ink comprises a carrier and a pigment colorant, and where the carrier substantially free of polymers. Additional steps include developing the ink to create a print image on the printing blanket; applying a layer of wetting fluid to a surface of a print medium, where the surface includes a coating comprising a polymer; heating the surface to a print-receptive temperature that is lower than the softening temperature of the polymer, causing softening of the polymer; and transferring the print image from the printing blanket to the surface.

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.

Techniques for protecting imaging access of electronic paper are described herein. For example, an electronic paper device with protected imaging access includes a substrate, an e-paper surface disposed on the substrate, a removable cover to prevent alteration of the e-paper surface when the cover is disposed over the e-paper surface, and a reversible locking mechanism engaging with the cover to secure the cover in place over the e-paper surface. A method for secure writing to e-paper is also provided.

A method of cleaning an image transfer blanket of an image forming apparatus is disclosed. The method includes establishing a temperature of a cleaner roller having a cleaner receiving surface to receive a cleaner layer in a first predetermined temperature range. The method also includes placing the cleaner layer disposed on the cleaner receiving surface in contact with the image transfer blanket and removing surface contaminants from the image transfer blanket to the cleaner layer.
