摘要： Systems and methods are provided for measuring a web. One embodiment is a measurement system that includes rollers which receive a web of print media marked with a printed job, a controller which determines that a segment of the web is stationary at the measurement system, an image measurement device that inspects the printed job, and a repositioning mechanism that repositions the segment within the measurement system relative to the image measurement device while portions of the web external to the measurement system remain stationary.

摘要： System and method for printer intrusion detection. One embodiment is a system that includes memory configured to store personnel identification data for a plurality of operator classes permitted to perform different levels of maintenance actions on a printer. The system also includes an intrusion detection controller configured to detect a presence of a person in an operating space of the printer based on image data, to analyze the image data to detect one or more characteristics of the person, to determine an operator class for the person based on a match of the detected characteristics of the person with the personnel identification data stored in the memory, and to monitor adherence to maintenance permissions by the person in a plurality of physical areas of the printer based on the operator class of the person.

摘要： Systems and methods are provided for image scaling with enhanced compression. One embodiment is a processor that receives an instruction to scale an input image to create an output image that is higher in resolution, and analyzes rows of the input image in sections according to a run length of a predetermined number of consecutive pels. For each run length of consecutive pels, the processor determines a cluster of adjacent pels within the run length having a color intensity value within a threshold range, and determines a replacement intensity value for the cluster based on at least one color intensity value of a pel in the cluster. The processor creates the output image by: upscaling the cluster by the scale factor to multiply a number of pels in the cluster, and changing an intensity value of all pels in the cluster to the replacement intensity value.

摘要： Systems and methods are provided for selectively qualifying printers for printing incoming jobs, based on an amount of colors within the job that the printers can reproduce. One embodiment is a system that includes an interface and a memory storing a print job defined in a job color space. The system also includes a controller that identifies colors specified by print data in the print job, determines coordinates of the colors in a perceptual color space, selects a printer, determines boundaries of a color gamut of the printer in the perceptual color space, and determines an amount of the colors that the printer is capable of reproducing. When the amount is greater than a threshold, the controller qualifies the printer for printing the print job. When the amount is less than the threshold, the controller disqualifies the printer from printing the print job.

摘要： Embodiments described herein provide determining an ink drop size. One embodiment comprises a system that includes a printhead fluidly coupled to an ink input supply, and a controller to direct the printhead to eject drops of ink of an ink drop type. The system further includes an ink output estimator to estimate an ink output amount ejected from the printhead based on an estimated quantity of the ejected drops of ink of the ink drop type and an estimated size of the drop type, and an ink measurement device to measure an ink input amount provided by the ink input supply to the printhead. The system also includes a correction module to adjust the estimated size of the drop type based on the ink output amount and the ink input amount for a printing operation.

摘要： A printer is described having a control unit and/or image processor to determine a number of pixels by which to scale an image along an axis of the image, wherein, the scaling of the image is less than 10% of the image along the axis. The control unit and/or image processor is also to identify locations along the axis equal to the number. The control unit and/or image processor is also to remove a region of more than one pixel along the axis at each of the locations. The control unit and/or image processor is also to insert a region of more than one pixel along the axis at each of the locations, where, a difference between pixels removed and pixels inserted accounts for the number.
