摘要： Techniques for generating dither masks are provided. A dither mask is generated by selecting a sequence of at least three original patterns comprising pixels of at least one of a first color and a second color. At least two patterns are interpolated to generate interpolated patterns in the sequence between the at least three original patterns. If a pattern having at least one specified characteristic exists in the sequence, the steps of interpolating between at least two patterns, and determining if a pattern having at least one specified characteristic exists in the sequence, are repeated. The interpolation is between at least one pattern from each side of the pattern having at least one specified characteristic in the sequence.

摘要： A method, computer program product and system for detecting and compensating for color misregistration. A black/white edge or a solid color edge on a target may be scanned. A black/white edge may refer to a black image, e.g., black text, on a white surrounding background having a rapid spatial transition from black to white. A solid color edge may refer to a solid color image, e.g., solid color text, on a white surrounding background having a rapid spatial transition from color to white. A curve of gray values versus spatial pixel positions for each color channel, e.g., red, green and blue color channels, may be generated. A misregistration error may then be calculated by calculating the offset between the color channel curves. The misregistration error may then be used to calibrate the scanner to compensate for the detected color misregistration.

摘要： Provided are a method, system, and program for generating threshold values in a dither matrix. A dither matrix of threshold values is generated. The threshold values in the dither matrix are filtered to generate a filtered dither matrix of filtered dither values by performing for dither values in the dither matrix: determining a region of dither values in the dither matrix that surrounds the value being considered, wherein the dither values in the determined region comprise one of dither values in a first portion of the region within the dither matrix or a wrap around dither value in a second portion of the region that extends beyond the dither matrix; and using an offset value to determine one wrap around dither value, wherein repeated instances of the dither matrix are designed to be applied to an image by forming a tile pattern of the repeated instances of the matrix over the image pattern, and wherein the repeated instances of the matrix in the tile pattern are offset in one direction by the offset value; and performing an operation on the determined dither values in the region to determine a filtered value for the dither value being considered.

摘要： A multiple beam printer system having N laser beams receives print job information from a print host. A rendering application uses a threshold array to generate halftone image data from the print job. The threshold array is defined based on a spot function. The defined screen is non-orthogonal and includes Y pels in a direction that is perpendicular to a scanning direction of the laser beams where Y is an integer multiple of N. A distance between screen dots in pels is preferably equal to an integer multiple of N. The screen dot may be defined by a supercell encompassing two screen dots and having an odd number of pels in a direction that is parallel to the scanning direction. The spot function may include a snap feature that snaps a screen dot to the nearest printer grid pel. The spot function may include scaling to compensate for the distortion of the non-orthogonal screen dot.

摘要： Systems and methods are provided for test patterns that detect misalignment. One embodiment is a printer that includes a marking engine having rows of nozzles. The rows are separated along a Y direction, and each row of nozzles extends in an X direction. The printer also includes a controller that directs the marking engine to print multiple bands of a test pattern. Each band is printed by selecting nozzles in a first row, selecting nozzles in a second row that occupy adjacent X positions to the selected nozzles of the first row, and forming a band having multiple marks. Each mark includes a continuous line from a nozzle in the first row and a continuous line from a nozzle in the second row. Each band of the test pattern is printed by ejecting ink from nozzles in a different combination of nozzles.

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.
