    摘要: One aspect of the method/apparatus finds, for each input-image pixel, an “offset weighted average” of neighboring-pixel interactions—and uses the averages to make a final image. Another aspect assumes a value for each pixel, to use in a final rendered image form—and, at each in a series of approximations, determines whether to change the value, and finds a probabilistic weight to help determine. Yet another finds, for each pixel, a numerical representation of neighboring-pixel interactions—and establishes a distance cutoff for use in defining “neighbor”, and uses the representation to decide whether to change color values. Still another finds a desired or ideal number of print passes, and adapts the number of passes actually used to the found number. Another combines halftoning and printmasking into one procedure and prints images prepared thereby. Another integrates halftoning and image filtering, to obtain esthetic visual effects, into one procedure—and prints images thus prepared.

    摘要: According to one aspect there is provided apparatus for generating a three-dimensional object. The apparatus comprises a first agent distributor to selectively deliver a coalescing agent onto portions of a layer of build material, a second agent distributor to selectively deliver a coalescence modifier agent onto portions of a layer of build material, and a controller to control the agent distributors to selectively deliver each of the agents onto a layer of build material in respective patterns derived from data representing a slice of a three-dimensional object to be generated, so that when energy is applied to the layer the build material coalesces and solidifies to form a slice of the three-dimensional object in accordance the patterns.

    摘要: The invention relates to a method of estimating the alignment in the printing medium direction between a first and a second pen of a printing system having a scan axis, whereby: the first, respectively second pen prints a first, respectively second pattern element; the first and second pattern elements are substantially aligned and separated by a space along the scan axis; each of the first and second pattern elements comprises a first and an associated second mark separated by a blank along the scan axis, the first and the second marks being staggered in the printing medium direction; an optical sensor scans along the scan axis over the first and second pattern elements, an analysis of the sensor output leading to estimating the alignment.
