摘要： A method and apparatus for processing image data is described. An example of a method involves applying a first mask to image data corresponding to an overlap zone of a first print region, the first mask representing a first mask pattern and applying a second mask to image data corresponding to the overlap zone of a second print region, the second mask representing a second mask pattern. Each of the first and second mask patterns define a periodic variation in a dimension corresponding to the first direction. First and second mask patterns for at least a second image plane are spatially separated in the dimension corresponding to the first direction in relation to first and second patterns of a first image plane.

摘要： In an ink jet recording apparatus including a carriage operative to move in scanning motion for printing characters and symbols on a printing surface and supporting thereon a single printing head having a plurality of ink jet nozzles or a plurality of printing heads each having a single ink jet nozzle, the printing surface is formed as a curved surface and the printing head or heads are constructed such that ink can be ejected radially with respect to the center of curvature of the curved printing surface. The vertical spacing between dots formed by ejected ink can be adjusted by moving the printing head or heads relative to the printing surface to thereby adjust the spacing between the printing surface and the printing head or heads, and the transverse spacing between the dots can be adjusted by adjusting the scanning speed of the printing head or heads or the ink ejecting timing.

摘要： In a continuous type ink jet printer having a conventional charging electrode for charging ink drops in accordance with a signal to be recorded on a record receiving medium, at least one, and preferably both of the deflection electrodes is mounted so that the deflection electrodes may be positioned in a first position by an actuator to allow for printing in a first direction. The actuator tilts the electric field to compensate for character inclination during carrier movement, and at the opposite end of the print line rotates the deflection electrodes to a second position to incline the electric field to compensate, during carrier movement in that opposite direction, for character inclination due to carrier movement in the second direction.

摘要： Electronic lead determining circuitry operates to advantage with nonconstant relative movement between a paper record medium and an ink drop projector carrier of ink drop printing apparatus. Electronic lead determining circuitry is arranged for calculating the proper lead times for displacing the normal print enabling signals by factors dependent on the actual carrier positions and the lead for projecting ink drops at the desired positions.Ink drop printing apparatus of the type having a carrier bearing an ink drop projector across a record medium at a velocity relative to the record medium which may be varying substantially--either by design or unintentionally--, and bearing print position location detecting elements, and bearing ink drop projection controlling elements is perfected by controlling electronic circuitry for calculating lead time at a given print position for enabling printing at a predetermined designated print position precisely at the predetermined desired location on the paper. Preferably, a velocity-time profile for the apparatus is chosen for low g-force loading of the moving components, and printing is effective over most of the profile in contradistinction to conventional printing over linear portions only of conventional profiles. Phase locked oscillator loop circuitry is used for tracking the carrier position and adjusting phase, while several alternate lead calculating circuits are arranged in cooperation therewith. Print position and carrier travel direction data are updated in real time as the apparatus operates under data processing control.

摘要： A system and method for applying patterns to surfaces. A pattern may be applied to a surface of an object using a three-dimensional (3D) printer system. The 3D printer system may include a printer head including an applicator holding material used to form the pattern on the surface, a structure configured to hold a substrate to which the material will be applied, and a controller for adjusting a location of the printer head relative to a surface and initiating applying material from the applicator onto the surface. The applicator may be a syringe with a needle. 3D coordinates at which material is to be applied to a surface to form the pattern may be determined and identified based on a relative location of the substrate and the pattern. The pattern may be a speckle dot pattern used in Digital Image Correlation (DIC) material testing and characterization techniques.
