    • A system selectively enables a printer to deposit on a sheet C, M, Y and K color dots at each of the plurality of pixel locations to produce a color image. The system comprises a memory for storing C, M, Y and K color values for each pixel in the color image and a processor for controlling selective deposition of the C, M, Y and K colors. The processor determines a gray value for each pixel location from values stored in the C, M, and Y color planes. The processor subtracts the determined gray value from the C, M, and Y values which correspond to the pixel location and then determines a relationship of the gray value to a non-linear function and in dependence upon the relationship alters the C, M and Y pixel values accordingly. The processor either (1) adds the gray value back to the C, M, and Y values for the pixel location, or (2) adds a first portion of the gray value to the C, M, and Y values for the pixel location and a second portion of the gray value to the K value for the pixel location; or (3) adds all of the gray value to a K value for the pixel location. As a result, the C, M, Y and K values are altered in accordance with the determined gray value. The altered color values are then prioritized and the processor determines which colors should be printed at each pixel location and diffuses color error values to neighboring pixel locations after such determination. The prioritization procedure enables print priority to be given to either the brightest color dot or to the color dot that is most visible to the human eye.
    • 系统选择性地使得打印机能够在多个像素位置中的每个像素位置处沉积在片材C,M,Y和K上的色点,以产生彩色图像。 该系统包括用于存储彩色图像中每个像素的C,M,Y和K颜色值的存储器和用于控制C,M,Y和K颜色的选择性沉积的处理器。 处理器根据存储在C,M和Y色彩平面中的值确定每个像素位置的灰度值。 处理器从对应于像素位置的C,M和Y值中减去确定的灰度值,然后确定灰度值与非线性函数的关系,并且根据关系改变C,M和Y 像素值相应。 处理器(1)将灰度值添加回像素位置的C,M和Y值,或者(2)将灰度值的第一部分添加到像素位置的C,M和Y值 以及所述灰度值的第二部分为所述像素位置的K值; 或者(3)将所有灰度值添加到像素位置的K值。 结果,C,M,Y和K值根据确定的灰度值而改变。 改变的颜色值然后被优先化,并且处理器确定在每个像素位置应该打印哪些颜色,并且在这样的确定之后将颜色误差值扩散到相邻像素位置。 优先顺序使打印优先级能够被赋予最亮的颜色点或人眼最为可见的颜色点。

    • A media binder has an inner assembly and a case assembly, The inner assembly includes inside boards pre-attached to a binding mechanism. Adhesive is placed on outward surfaces of the inside boards. The case assembly includes a cover sheet with at least one marginal edge attached to surface boards and at least one loose edge. To customize cover, a printed cover is inserted in-between the cover sheet and the surface board through an opening formed by the loose edge. The case assembly is then laminated. The laminated case assembly is combined with the inner assembly using the adhesive on the inside boards. A one-piece media binder has cover sheets wrapping around surface boards forming pockets. The surface boards are partially attached to paste downs. To customize cover, printed covers are inserted into the pockets, and the paste downs are then attached to the surface boards to seal loose edges.
    • 介质粘合剂具有内部组件和壳体组件。内部组件包括预先附接到结合机构的内部板。 粘合剂放置在内侧板的外表面上。 壳体组件包括具有附接到表面板和至少一个松散边缘的至少一个边缘的覆盖片。 为了定制盖子,通过由松散边缘形成的开口将印刷的盖子插入盖板和表面板之间。 然后将壳体组件层压。 层压壳体组件使用内侧板上的粘合剂与内部组件组合。 单件介质粘合剂具有围绕形成袋的表面板的覆盖片。 表面板部分连接到粘贴。 为了定制盖子,将印刷的盖子插入袋中,然后将粘贴物附接到表面板以密封松散的边缘。
