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： An organic acid component is employed 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). The organic acid component is employed at a concentration ranging from about 0.25 to 20 wt % and may be represented by such as acids as polyacrylic, acetic, glycolic, malonic, malic, maleic, ascorbic, succinic, glutaric, fumaric, citric, tartaric, lactic, sulfonic, ortho-phosphoric acid, derivatives thereof. Without the organic acid component, a pH differential on the order of at least 4 and more likely 5 units must exist between the pH-sensitive ink and the target ink to substantially eliminate bleed. By employing an organic acid in the practice of the invention, a pH differential on the order of only 1 to 3 units may be required. Therefore, assuming the pH-sensitive ink has a pH of about 8, the pH of the target ink could be as high as 7 in the practice of the invention as opposed to a pH of about 3 in the absence of an organic acid component.
摘要翻译：在第一喷墨油墨组合物中使用有机酸组分以降低使第二侵入式喷墨油墨组合物的pH敏感着色剂变成不溶性所需的pH差异。通过诱导pH敏感着色剂的沉淀，着色剂的迁移被抑制，从而大大减少了pH敏感性油墨和含有机酸的油墨（“目标”油墨）之间的渗色。有机酸组分的使用浓度范围为约0.25至20重量％，可以由诸如聚丙烯酸，乙酸，乙醇酸，丙二酸，苹果酸，马来酸，抗坏血酸，琥珀酸，戊二酸，富马酸，柠檬酸，酒石酸，乳酸，磺酸，正磷酸，其衍生物。没有有机酸组分时，pH敏感油墨和目标油墨之间必须存在大约至少4个数量级，更可能5个单位的pH差异以基本上消除渗色。通过在本发明的实践中使用有机酸，可能需要大约1至3个单位的pH差。因此，假设pH敏感性墨水的pH值约为8，与实施例1相比，在不存在有机酸成分的情况下，目标油墨的pH值可高达7。

摘要： A method for producing a clear, vivid and water-fast printed image on a substrate. An ink is used which contains a sublimable dye diffusion thermal transfer coloring agent. The substrate includes a backing layer and an ink absorbent layer on the backing layer. The backing layer is designed to receive the coloring agent therein after sublimation of the coloring agent. The ink is initially delivered to the ink-absorbent layer. The substrate is then heated to cause sublimation of the coloring agent and diffusion of the sublimed coloring agent into the backing layer. Pressure may also be applied during the heating process. In addition, the ink can be retained within an ink cartridge in a printer unit, with the cartridge having at least one ink ejector. Heating of the substrate may then be accomplished by a heating member in the printer unit which contacts the substrate.
摘要翻译：一种在基板上产生清晰，鲜明和水快的印刷图像的方法。使用含有可升华的染料扩散热转印着色剂的油墨。衬底包括背衬层和背衬层上的墨吸收层。背衬层设计成在着色剂升华之后接收其中的着色剂。墨水最初被传送到吸墨层。然后加热底物引起着色剂的升华和升华的着色剂扩散到背衬层中。也可以在加热过程中施加压力。此外，墨水可以保持在打印机单元中的墨盒内，墨盒具有至少一个墨水喷射器。然后可以通过接触基板的打印机单元中的加热构件来实现基板的加热。
