摘要： An inkjet drop ejection system comprises a combination of printhead components and ink, mutually tuned to maximize operating characteristics of the printhead and print quality and dry time of the ink. Use of a short shelf (distance from ink source to ink firing element), on the order of 55 microns, provides a very high speed refill. However, it is a characteristic of high speed refill that it has a tendency for being over-damped. To provide the requisite damping, the ink should have a viscosity greater than about 2 cp. In this way, the ink and architecture work together to provide a tuned system that enables stable operation at high frequencies. One advantage of the combination of a pigment and a dispersant in the ink is the resultant higher viscosity provided. The high speed would be of little value if the ink did not have a fast enough rate of drying. This is accomplished by the addition of alcohols or alcohol(s) and surfactant(s) to the ink. Fast dry times are achieved with a combination of alcohols, such as iso-propyl alcohol with a 4 or 5 carbon alcohol or with iso-propyl alcohol plus surfactant(s). One preferred embodiment of a short shelf (90 to 130 microns), ink viscosity of about 3 cp, and surface tension of about 54 provides a high speed drop generator capable of operating at about 12 KHz. Reducing the shelf length to about 55 microns, in combination with rotating the substrate at an angle to the scan direction, permits maximum drop generator operation as high as about 20 KHz. As a consequence of employing pigment-based inks, high optical densities are realized, along with excellent permanence (no fade and better waterfastness), and good stability. The combination of preferred ink and pen architecture provides good drop generator stability.

摘要： An inkjet ink is provided that has a greater organic content than prior art inks. However, it is not simply enough to increase the organic content; other factors must be considered as well. These include controlling viscosity and surface tension, as well as maintaining acceptable drytime. An inkjet ink composition that evidences reduced outgassing and reduces paper cockle and curl comprises about 25 to 50 wt % of one or more organic co-solvents, has a viscosity of 10 cp or less, and has a surface tension of 40 dyne/cm or less. Advantageously, using a higher solvent ink reduces cockle and curl. Cockle and curl are also reduced as the water content of the ink is reduced. The present invention uses the higher solvent inks in combination with underprinting. In underprinting, a fixer solution is first “printed” on the print medium, followed by printing the inkjet ink thereon. There is a synergism to this combination. Together, weaknesses of both approaches are addressed. The advantages are a longer life pen, due to the reduction of outgassing of the ink, and reduced cockle and curl.
摘要翻译：提供了一种具有比现有技术油墨更大的有机物含量的喷墨油墨。但是，增加有机含量还不够简单。还必须考虑其他因素。这些包括控制粘度和表面张力，以及保持可接受的干燥时间。包含约25〜50重量％的一种或多种有机助溶剂的粘度为10cp或更低的喷墨油墨组合物，其表现出减少的除气和减少纸le le和卷曲的表面张力为40达因/厘米或减。有利的是，使用较高溶剂的墨水可以减少鼻孔和卷曲。随着墨水的含量降低，鸡尾酒和卷曲也减少。本发明使用较高溶剂油墨与底印组合。在底印中，定影剂溶液首先在打印介质上“印刷”，随后在其上印刷喷墨油墨。这种组合有协同作用。两种方法的缺点在一起得到解决。优点是寿命长的笔，由于减少了油墨的脱气，并减少了起皱和卷曲。

摘要： Aqueous ink compositions containing anti-curl agents substantially reduce or eliminate paper curl in plain-paper printed elements without adversely effecting storage stability, decap properties or print quality, and thus eliminate the need for expensive and bulky mechanical curl-arresting devices or special curl-resistant substrates. Printing the inks on plain-paper substrates is the sole step in a process for reducing paper curl in plain-paper printed elements.

摘要： A color ink-jet printer is provided, with one pen for dispensing black ink onto a print medium and at least one pen for dispensing color ink onto a print medium. The pen for dispensing black ink contains a pigment-based ink and the pen(s) for dispensing color ink contain a water-miscible dye-based ink. Such a color ink-jet printer provides both superior text quality (black ink) and relative ease of service (color inks), since the black ink is used more than the color inks and thus tends to require less spitting due to its frequency of use. On the other hand, since the color inks are used less, the utilization of water-miscible inks, which require less spitting than pigmented inks to keep the nozzle clear, also require less spitting even with relatively lower frequency of use.
摘要翻译：提供了一种彩色喷墨打印机，其中一支笔将黑色墨水分配到打印介质上，以及至少一根笔，用于将彩色墨水分配到打印介质上。用于分配黑色墨水的笔包含颜料基墨水，并且用于分配彩色墨水的笔包含与水可混溶的染料基墨水。这种彩色喷墨打印机具有优异的文字质量（黑色油墨）和相对的易用性（彩色油墨），因为黑色油墨比彩色油墨更多使用，因此由于其使用频率而倾向于需要较少的吐痰。另一方面，由于使用较少的彩色油墨，因此即使在相对较低的使用频率下，也可能需要较少的喷射，因此与颜料油墨相比较少喷墨以保持喷嘴清洁的水混溶性油墨的使用也需要较少的喷射。

摘要： A color ink-jet printer is provided, with one pen for dispensing black ink onto a print medium and at least one pen for dispensing color ink onto a print medium. The pen for dispensing black ink is adapted to jet droplets of black ink of a first volume and the pen(s) for dispensing color ink are adapted to jet droplets of color ink of a second volume, with the first volume being larger than the second volume. Such a color ink-jet printer provides both superior text quality of the black ink and does not require as much ink volume of the color ink(s) as previous ink-jet printers.
