Disclosed is a process for "white glove" replenishment of a thermal ink jet printer wherein the nonaqueous ink components are separated from the water and encapsulated in a water soluble shell. The ink is reconstituted in the machine sump by first adding a measured quantity of the capsules, followed by addition of the water. The capsules have the advantage of being much easier to handle than a conventional ink, and are less likely to contaminate other surfaces if accidentally spilled.
