摘要： Exemplary embodiments provide a roll member that includes one or more controllable cells and methods for making and using the roll member to control an image (or toner) state thereon. The controllable cells can be disposed on a roll substrate and configured in a manner that each controllable cell can be addressed individually and/or as groups. Each controllable cell can be addressable to provide a surface vibration to release toner particles adhered/attracted thereto and can also be capable of sensing the toner state of the roll member and thus to control the image or toner state. In an exemplary embodiment, the disclosed roll member can be used as a donor roll for a development system of an electrophotographic printing machine to create controlled and desired toner powder cloud for high quality image development.

摘要： A method for estimating the color of a coated print includes: measuring the color of an uncoated print with a color measuring device; and estimating the color of the print when coated by a coating process based on the uncoated color measurement using a function that correlates uncoated color measurements and coated color measurements; and adjusting at least one parameter of the printing process based on the coated color estimation. The correlating function may be derived by measuring the color of a plurality of uncoated color patches; measuring the color of the plurality of patches after the patches have been coated by the coating process; and correlating the color of the coated patches with the uncoated patches based on the coated and uncoated color patch measurements.

摘要： Exemplary embodiments provide a direct imaging system and methods for direct marking an image using the system. The disclosed direct imaging system can eliminate the use of at least one of a charge, and/or exposure subsystems in an electrostatographic machine and related processes. Specifically, the direct imaging system can include a direct marking substrate (e.g., a printing substrate) and a development roll member closely spaced from the direct marking substrate. In one embodiment, the development roll member can include a plurality of actuator cells with each actuator cell controllably addressable to eject one or more toner particles adhered thereto. The ejected toner particles can transit the space between the donor roll member and the direct marking substrate, and thereby marking onto the direct marking substrate forming an image.
