Abstract

The present invention provides ink-jet inks and methods for increasing slewing time of an ink-jet ink pen without significant decap. The composition can comprise an effective amount of a dye, an effective amount of an ink vehicle, and an effective amount of an anti-slewing decap agent comprising an alkyl aryl sulfonamide. In one embodiment, the anti-slewing decap agent consists essentially of the alkyl aryl sulfonamide. With regard to the method, the steps can including formulating the composition; loading the ink-jet ink in an ink-jet pen; and configuring the ink-jet pen to allow for increased slewing time between firing. Additionally, a system of printing high quality images with reduced slewing decap can comprise an ink-jet ink pen configured for firing non-image producing spits at from 3 and 6 second intervals, an ink-jet ink composition having an effective amount of an alkyl aryl sulfonamide present, and a substrate for accepting the ink-jet ink composition such that the high quality image is formed.
