摘要： A dynamic reimageable document or electric paper can be formed from ordinary substrates such as paper, transparencies or fabric by printing of microencapsulated Gyricon beads onto one or more discrete surface areas of the substrate. The substrate can include both fixed print regions formed by conventional fixed ink processes and dynamic reimageable regions formed by the Gyricon beads. The Gyricon beads are preferably bichromal and of contrasting colors, such as black/white so as to be changeable to display two states by selective application of electromagnetic force to the beads. By providing bichromal beads in differing color combinations, such as red/white and black/white, a multi-colored document can be achieved in which various fields of the document, representing text, images or graphics, may be in differing colors. Moreover, operations to perform both imaging or erasure can act on the discrete reimageable regions so that the versatility of the electric paper can be enhanced. The Gyricon beads may be dispersed in a solution to form a liquid Gyricon toner that can be directly marked, such as by a jet nozzle, into a desired pattern on the substrate.
摘要翻译： 通过将微胶囊化Gyricon珠粒印刷到基底的一个或多个离散的表面区域上，可以由诸如纸，透明胶片或织物的普通基材形成动态可再成像的文件或电纸。 衬底可以包括通过常规固定油墨工艺形成的固定印刷区域和由Gyricon珠形成的动态可再形成区域。 Gyricon珠子优选是双色的，并且具有对比色，例如黑色/白色，以便通过选择性地向珠粒施加电磁力来显示两种状态。 通过提供不同颜色组合的双色珠，例如红/白和黑/白，可以实现多色文档，其中表示文本，图像或图形的文档的各个领域可以具有不同的颜色。 此外，执行成像或擦除的操作可以作用于离散的可再成像区域，使得可以增强电纸的通用性。 Gyricon珠可以分散在溶液中以形成液体Gyricon调色剂，其可以通过喷嘴直接标记成基底上所需的图案。

摘要： Methods and techniques of electrically biasing and providing a ground for migration imaging members are disclosed. An electrically conductive contact is fixed to the migration imaging member, the electrically conductive contact connecting at least an electrically conductive layer of the migration imaging member to a ground to insure proper imaging. The contacts are fixed to the migration imaging member without having to remove a portion of the softenable layer along its edge to expose the electrically conductive layer of the migration imaging member as is the current practice.
