    Abstract: A method of printing with an ink-jet printer. The method includes printing a dye onto a substrate, printing a deactivating agent on the dye, causing the agent to react with either the dye or the substrate, and washing the substrate. The invention is also an ink-jet cartridge having a plurality of reservoirs, some of which contain an ink having a dye and at least one of which contains a deactivating agent.

    Abstract: An ink set providing reduced differential lightfade and graininess. The ink set comprises at least one dark inkjet ink and at least one light inkjet ink. The dark inkjet ink comprises at least one pigment having a high chromaticity and a low lightfastness and the light inkjet ink comprises at least one less chromatic pigment having a high lightfastness. The pigment in the dark inkjet ink is dissimilar from the pigment in the light inkjet ink in at least one of a crystal form, particle size, chromophore, and chemical dispersant. A method of reducing differential lightfade and graininess in a printed image is also disclosed.

    Abstract translation: 一种提供降低的差分光衰和颗粒度的油墨组。 油墨组包括至少一种深色喷墨油墨和至少一种轻质喷墨油墨。 深色喷墨油墨包括至少一种色度高，耐光性低的颜料，并且轻喷墨油墨包括至少一种耐光性较差的少色颜料。 深色喷墨油墨中的颜料与光喷墨油墨中的颜料不同，其中至少一种是晶体形式，粒度，发色团和化学分散剂。 还公开了减少打印图像中的差别光衰和颗粒度的方法。

    Abstract: An inkjet ink having an increased shelf life. The inkjet ink comprises an ink vehicle and a reactive colorant. The reactive colorant is nonreactive with water,thereby increasing the shelf life of the inkjet ink to greater than approximately twelve months. An inkjet printing system comprising the inkjet ink and an activating agent is also disclosed. A reactive colorant of the inkjet ink is nonreactive with water but is sufficiently reactive with the activating agent to form an activated complex to fix the reactive colorant to a textile substrate. A method of printing on a textile substrate is also disclosed.
