    摘要： An imaging member is disclosed having a surface layer comprising a heat-sensitive material whose surface compatibility to printing agents, such as toners and inks, can be substantially reversed in response to small changes in temperature. The imaging member is suitable for use in lithographic and printing applications, permitting reversible switching between compatibility states of printing agents, such as between hydrophilic and hydrophobic states or oleophilic and oleophobic states, and enabling rapid production of images on a recording medium.

    摘要： A printing apparatus or printing system that uses multiple print engines to form an image on a substrate. The printing apparatus or printing system may be a surface printing system or a reverse printing system. Each of the multiple print engines has at least one color station. The color stations are arranged in the print engines and between the multiple print engines based on whether the printing system is a surface printing system or a reverse printing system to control the order in which colorant is formed on a substrate. Multiple print engines allow for, among other things, a greater color gamut and therefore assists in expansion of the standard color gamut.

    摘要： A method and system to control ink keys for a printing machine is provided. The ink keys are adjustable to control ink feed to individual zones located across the width of an ink roller. Feedforward and feedback control loops adjust the ink supply dynamically based on a pixel count of the image content. The pixel count looks ahead in the video stream to allow time for the adjustment at the inker keys to propagate through the ink train to affect ink output onto the imaging drum. Feedback of the achieved ink density on control patches on the imaging drum is also used to command the inker key motors. Feedback is also used to update the inker propagation delay and dynamic model used to determine how much the inker keys need to be adjusted based on the pixel count stream.
