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。
