A workflow is developed for the at least one of the multiple void pantographs having both i) the covert or semi-covert pantograph foreground and background after printing, and ii) the overt pantograph foreground after scanning.

This information is used to automatically adjust the general printing procedure for a print engine.

Abstract: An image-reading device includes a plurality of image sensors, a starting signal generator and a signal timing regulator. Each image sensor reads images on a pixel basis and generating an image signal indicative of the image. The image signal is an analog signal. The starting signal generator generates starting signals at every predetermined time period. A sampling period for sampling the image signal is set within the predetermined time period. In response to the starting signal sequentially inputted to the image sensors, the image sensors read the image until the predetermined time period is expired. The signal timing regulator delays an input timing at which the starting signal is inputted to the image sensor so that the sampling periods for the plurality of image sensors are different from one another.

Abstract: Methods and apparatus for optimizing the phase lock loop circuitry of sub-pixel clock generators for situations where frequent switching between different system printing speeds, and hence clock frequencies are required.

Abstract: A processing system may include a server group connectable to an image forming apparatus, a request processing unit, a backend processing unit, a receiving unit, a determination unit, and a sending unit. The receiving unit receives information relating to a document file corresponding to a processing request from the image forming apparatus. If the determination unit determines that that the processing method is a synchronous processing method, then the request processing unit processes the document file based on the processing request. If the determination unit determines that that the processing method is an asynchronous processing method, then the request processing unit requests the backend processing unit to process the processing request. After the document file has been processed according to the determined processing method, the sending unit sends a notification to the image forming apparatus that the document file has been processed.

Abstract: Determining a spectral gamut of a device by designating a spanning set of samples which span the spectral gamut. A first crude spanning set of samples is established by specifying one or more corresponding device values in a device color space. The first crude spanning set is refined by processing a plurality of new samples in a predetermined order. The processing includes, for each new sample, determining if the new sample differs in an objective function value by more than a predetermined threshold from all samples in the first crude spanning set and adding the new sample to the first crude spanning set if the new sample differs in the objective function value by more than the predetermined threshold. The resulting first crude spanning set is designated as the spanning set of samples.
