    摘要： A fluid interconnect for a component of a printer is disclosed. The component may, for example, be an inkjet printhead removably attached to a printer and having an ink inlet configured to receive ink from an ink supply. The fluid interconnect has a sealing surface configured to form a seal when contacted against a opposing sealing surface on another component of a printer ink delivery system, and carries a surfactant sealant.

    摘要： Various ink formulations utilizing particular magenta dyes have excellent printing characteristics with high chroma and good lightfastness on plain paper and minimal humid bleed and hue shift on special media. The magenta humid bleed shift has been greatly reduced, especially on photo glossy materials. A single dye may be used in comparison to blended dyes which have been used in the past.

    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： Certain colorants become insoluble under specific and well-defined pH conditions. By forcing a colorant to become insoluble on the page, migration of the colorant is inhibited, thereby helping to reduce bleed between inks of different colors. The colorant is forced out of solution from the ink by contact with another ink having the appropriate pH (either higher or lower than that of the first ink). In particular, an ink containing a colorant comprising a pigment in combination with a pH sensitive dispersant is used in conjunction with an ink of the appropriate pH.

    摘要： An improved ink composition having an additive therein for reducing the surface tension of the composition and increasing the drip mass per firing. Reduced surface tension and increased drop mass per firing enable the production of graphic images having enhanced clarity and contrast while avoiding problems such as bubble adhesion/longevity and ink mottling/coalescence. The additive basically consists of at least one polyether polyol. The additive is usable in a wide variety of ink compositions. In a preferred embodiment, ink compositions using the additive will include about 0.001-1.0% by weight additive (0.0075%=optimum). The resulting ink formulations are capable of printing high resolution graphic images while avoiding the problems described above.
