Color and process color dry toners and compatible toning systems for use in high-speed electrographic digital printing

摘要

A non-magnetic toning system for inclusion in a magnetic toning system is disclosed. Further the invention is directed to the process of color imaging, which can be divided into two main categories: (1) line, highlight, or imaging, wherein a permanent toned image of a color, including black, is produced using toner particles of a single color; and (2) process, or “near photographic” color imaging, wherein a permanent toned image is produced by selectively blending or mixing toner particles of two or more primary colors. The invention is directed to an interchangeable Non-Magnetic Toning System (“NMTS”) using specific toners in compatible printing machines. The NMTS using specific toners will be useful in printing machines currently on the market using magnetic toning systems. More particularly, specific toners of this invention relate to dry toners, which may advantageously be used in color imaging, black text, and MCRI printing, and the compatible toning system required for transferring the dry toners to a latent electrostatic image created within an electrophotographic or electrographic printing system.
