    摘要: An Ink-based digital printing system comprises an external fluid applicator for applying multi-component, multi-functional fountain solution to a surface of an imaging plate. The plate is image wise exposed using a high power laser to remove primary components of the fountain solution from select regions of the plate according to digital image data, leaving a layer of the secondary components at said select regions. The plate is then inked with ink useful in printing. The ink adheres to the select regions from which the primary components have been removed to form an ink image. The ink image is transferred at an image transfer step wherein the secondary components enable efficient transfer of the ink to a medium with reduced image quality defects. The multi-component fountain solution comprises primary components that reject or repel ink, and secondary components that function as a release agent.

    摘要: A control system and method of predicting how a machine will respond to occasional or periodic service, and adjusting the machine accordingly to account for the change in machine behavior due to the service, mitigates transients in machine performance. A prediction of the service effect is fed forward to the existing control system just prior to the occurrence of service in order to compensate for the service effect. This prediction is continually updated and refined using subsequent measurements of the effect of service on machine performance. More specifically, a controller monitors the process output variables indicative of the machine performance and adjusts machine inputs to achieve a desired level of machine performance. The controller monitors the process output variables indicative of the machine performance prior to, during, and immediately after the service and adjusts the machine inputs to compensate for the transients.
