    • Haptic or tactile features, which are generally not visually perceptible or reproducible, are applied at varying positions on a substrate according to a predetermined scheme. A plurality of raised image areas are specified for a group of substrates and raised marks are printed in only one raised image area for each substrate in a manner that is evenly distributed between the raised image areas for the group of substrates. The substrates will present a relatively uniform stack avoiding localized large pile heights when the substrates are stacked. A clear marking material is used to print the raised marks so as not to obscure underlying data printed on the substrate. The clear marking material may include a monomer that may become cross-linked in an exposure process to resist deinking of the substrate. The clear marking material may be mixed with a phosphorescing or fluorescing material as an additional security measure.
    • 根据预定方案,通常在视觉上不可感知或可再现的触觉或触觉特征应用于基板上的变化位置。 对于一组基板指定多个凸起图像区域,并且以均匀分布在用于该组基板的凸起图像区域之间的方式,在每个基板的仅一个凸起图像区域中印刷凸起标记。 当衬底堆叠时,衬底将呈现相对均匀的堆叠,避免局部的大桩高度。 使用清晰的标记材料来印刷凸起标记,以免遮蔽印刷在基底上的底层数据。 透明标记材料可以包括可以在曝光过程中交联以防止基底脱墨的单体。 透明标记材料可以与磷光或荧光材料混合,作为额外的安全措施。

    • An embodiment is a method and apparatus to meter ink for electrographic printing. An ink loading mechanism having an anilox roller fills ink from an ink supply into cells in the anilox roller having a plurality of valleys and lands that form the cells. The ink loading mechanism causes the valleys to be full or nearly full with the ink. The anilox roller rotates in a first direction. A blanket roller rotationally engaged with the anilox roller pulls the ink out of the cells and causes the valleys to be partially filled. The blanket roller rotates in a second direction. A first cleaning blade cleans tops of the lands of the cells.Another embodiment is a method and apparatus to meter ink for electrographic printing.

    • A dual level encryption method, and document, for providing and obtaining a substantially increased amount of optically readable information from an otherwise conventional and highly visible printed bar code pattern area on a document without interfering with the conventional optical reading of the conventional information in the bar code, comprising integrally printing a second and very much finer pattern of encoded optically machine readable glyph code or other such indicia within the bar code pattern area, containing a much higher level of information, to provide two different levels of information within the same area. Scanning the bar code pattern with a conventional bar code reader extracts conventional bar coded information embedded in the bar code without interference from the second indicia. Scanning the same bar code pattern area with a different, higher resolution, optical scanner extracts the much greater amount of information from the second, much finer, optically readable indicia pattern.

    • A method and apparatus for overloading operators in Page Description Language (PDL) defined graphics redefines the graphic, such as to compensate for certain undesirable line growth characteristics of a target printer or display device. Line width can be controlled based on various attributes, such as color, size, width, pattern or orientation. Line width can be redefined to be wider, narrower or of a differing color to achieve a desired printed graphic. Also, the method and apparatus can compensate for fill in of reverse-line and “cookie-cutter” holes. The method, performed within a decomposer, examines individual lines of a PDL defined graphic, determines if compensation is needed to achieve a desired printed output, and redefines an operator to achieve the compensation. The compensation can include addition of wider reverse (white) lines under colored lines to prevent the fill in.

    • A control system for a xerographic printer utilizing hybrid scavengeless development in the marking process which selectively adjusts process parameters for closed loop feedback control to maintain a preselected tone reproduction curve. The curve is selected to enhance the effectiveness of the range of distinguishable densities in a printing device. The system monitors a series of control patches of varying area coverage density and compares the representative values from the sensor patches with preselected target values. When the measured value significantly departs from the target value, control steps are implemented to affect the toner powder cloud height in the development zone to either add or decrease the mass of toner powder deposited on the photoreceptor.
