摘要： A method of calculating compensation data for compensating for spatial print engine non-uniformity of an image applied by a print engine to a receiver. A test target has two test areas of different output densities, each with a single output pixel level. A relationship between output density and output pixel level for the print engine is determined, and is used to calculate the output pixel level for each test area from the respective output density. The test target is printed, and the reproduced densities of the test areas are measured at a plurality of different locations in each area. A processor is used to calculate the compensation data using the measured densities. The compensation data defines a relationship between an output pixel location on the receiver, an output pixel level, and a compensated pixel level.

摘要： Automatically determining the cost of a printed job on a digital printing press before the job is run. A job control component in the digital front end of the printing press collects and stores the processing information from the job processing components from prior runs. A job-reporting component displays the stored and estimated processing information and automatically computes and displays the estimated cost of the job. The method includes determining a future toner cost using a toner cost, a future press usage cost, and a substrate cost based on historical toner consumption and then rasterizing the job to determine the total job cost.

摘要： One or more printers or printing systems are connected to a scanning device. Each printer includes one or more color modules that are used during a printing operation. A printer prints a target for each color module or color channel. The printed targets are then scanned by the scanning device. The printed targets may be rotated to any angle and then scanned by the scanning device. The scanned raster data is processed by a controller to detect non-uniformities in at least one density image and to generate one or more correction profiles for the printer. When an image is to be printed, one or more controllers receive the image data and use the one or more correction profiles to correct or compensate for the non-uniformities during the exposure process. A color module may include a LED printhead.

摘要： In the method, a digital image is received. A granularity model is constructed of each of the toner stations. A noise table is produced. The noise table is based on the granularity models and is adaptive to the content of the digital image. Noise is reduced in the digital image using the noise table. The digital image is divided into a plurality of color records, each corresponding to a respective toner station. The color records of the noise reduced digital image are printed using respective toner stations. Each granularity model defines a toner applied by the respective toner station.

摘要： A method of printing a job having a type using an electrophotographic (EP) printer includes receiving the job and its type. A processor is used to automatically select a first or a second job mode based on the job type; the first job mode indicates aggressive gray component replacement (aGCR) is used but not clear toner, and the second job mode indicates clear toner is used but not aGCR. The data of the job are processed using the processor according to the selected job mode to provide six separations corresponding to respective colorants. Toner corresponding to the six separations is then applied to the receiver using at least one EP printing module in the EP printer to produce a print image of the job.
