摘要： One or more reactive color inks are printed under and over black text and graphics areas. That is to say, one or more reactive color inks are first printed in a selected area in which black text and/or graphics are to be printed, then the black text and/or graphics are printed, and finally one or more reactive color inks are then printed over the black text and/or graphics. The use of under- and over-printing of black text and/or graphics by reactive color inks improves several important characteristics of inkjet printing. Specifically, the following improvements are obtained: dry-time, finger smudge, media independence/print quality, waterfastness, strikethrough, less noticeable missing/misdirected nozzles, and no dedicated pens are required. Alternatively, either underprinting alone or overprinting alone may be used.
摘要翻译：一个或多个反应性颜色墨水印刷在黑色文本和图形区域之下。也就是说，首先将一个或多个反应性颜色墨水印刷到要打印黑色文本和/或图形的选定区域中，然后打印黑色文本和/或图形，最后打印一个或多个反应性颜色墨水然后印在黑色文字和/或图形上。通过反应性颜色油墨使用黑色文字和/或图形的欠印刷和超印刷改善了喷墨印刷的几个重要特性。具体来说，可以获得以下改进：干燥时间，手指污迹，介质独立性/打印质量，耐水性，删除线，缺少/不正确的喷嘴，不需要专用笔。或者，可以单独使用底印或单独的套印。

摘要： The present invention relates to electrochromic solutions and devices manufactured therefrom. More precisely, the present invention relates to electrochemichromic compounds and processes for preparing the same. The present invention also relates to electrochemichromic solutions of such compounds, and those devices manufactured with the same, that demonstrate superior responsiveness to those solutions known heretofore when an applied potential is introduced thereto. And, these solutions, when contained within electrochemichromic devices, demonstrate ultraviolet stability, thermal stability and cycle stability. The responsiveness observed in terms of solution coloring with respect to the solutions, and devices containing the same, of the present invention is of a greater rapidity, intensity and uniformity than those electrochemichromic solutions of the prior art. Preparation of these solutions involve the novel process of pre-treating at least one of the electrochemichromic compounds with a redox agent prior to placing it in contact with the other electrochemichromic compound. Moreover, the present invention relates to methods of preparing such novel solutions and processes for using these solutions to provide devices that exhibit and benefit from the aforementioned superior characteristics.

摘要： A black printhead is installed in a scanning carriage with at least one primary color printhead on both sides of the black printhead. To reduce the drying time of a printed black ink pattern and to achieve other benefits, a first one of the primary color inks underprints the black ink in a first scan direction, and a second one of the primary color inks underprints the black ink in an opposite second scan direction. To minimize hue shifts due to the different underprinted colors, the black ink is overprinted, during the same scan that printed the underprinted ink and black ink, by a color ink that is different from the underprinted ink, so that the resulting black image printed in both scan directions will contain the same three color components. In one embodiment, the order of print cartridges in the scanning carriage, as viewed from the front of the printer, is cyan, black, magenta, and yellow. Other orders may also be used, and additional colors may be used. The invention is also applicable to a color printer using a single printhead with multiple sets of nozzles, each set printing a different color ink.

摘要： A pH adjusting organic compound having both at least one acid functional group and at least one basic functional group is employed along with an organic acid having no basic functional groups in a first ink-jet ink composition to reduce the pH differential required to render insoluble the pH-sensitive colorant of a second encroaching ink-jet ink composition. By inducing the precipitation of the pH-sensitive colorant, migration of the colorant is inhibited, thereby substantially reducing bleed between the pH-sensitive ink and the ink containing the organic acid (the "target" ink). By employing an organic acid in the practice of the invention, a pH differential on the order of only 3 to 5 units may be required. Aside from increasing the pH of the ink to desirable levels, the pH adjusting organic compound enhances bleed control by increasing the concentration of acid functional groups beyond the amount provided by the organic acid component. The organic acid component is employed at a concentration ranging from about 0.1 to 20 wt % and may be represented by such acids as polyacrylic, acetic, glycolic, malonic, malic, maleic, ascorbic, succinic, glutaric, fumaric, citric, tartaric, lactic, sulfonic, and ortho-phosphoric acid and derivatives thereof. The pH adjusting organic compound is employed in sufficient amount (about 0.1 to 20 wt %) to achieve the desired pH differential and typically comprises an amino acid.
