    摘要: In order that ink leakage be reduced from a compressed foam storage ink container for an inkjet printer cartridge, at least one of the walls of the container is provided relief pockets having air spaces free of the compressed foam. At least one vent channel communicates between relief pockets and ambient air pressure to provide pressure equilibrium.

    摘要: A quantizing unit, error detector, error diffusion matrix, and adder quantize a pixel of interest of an input image by an error diffusion method. A calculation unit and gain adjuster calculate a value to be added to the pixel of interest with reference to quantized pixels. The adder adds the calculated value to the pixel of interest. A control unit controls the calculation of the gain adjuster.

    摘要: A halftone screen which is applicable to a low-resolution electrophotographic printer is created. Hence, dot-lattice points arranged in a predetermined region are displaced using rotation processing, the predetermined region is partitioned into polygons each of which surrounds the dot-lattice point. Then, a threshold matrix used to grow a halftone dot, which is surrounded by each polygon, in a direction of the displacement is generated.

    摘要: A porous foam based ink containment system is provided with grooves defined in the exterior portion thereof, for storing ink, while preventing ink leakage from the ink-jet pen. The grooves provide passageways to allow air diffused throughout the ink and trapped air bubbles within the foam to expand and move to the atmosphere. An atmospheric vent is in fluid communication with at least one of the grooves.

    摘要: A monolithic inkjet printhead is formed using single-side fabrication processes. Printing elements and feed channels are formed by processes working from a top of the die. During formation of the printing elements filler material is applied to the feed channel. Such material is later removed by an anisotropic etch. Such etchant works from the top surface and a side edge of the substrate. The single-side fabrication process is distinguished from fabrication processes that work from a bottom of a die to form the feed channel and fill channels and work from a top of the die to form printing elements.
