An example of an ink supply includes an ink chamber containing a liquid ink, a salt chamber containing a salt solution, a separator positioned between the liquid ink and the salt solution, and a release mechanism. The separator completely separates the liquid ink from the salt solution prior to the release mechanism being triggered. The release mechanism has a triggered position and a retracted position. The triggered position causes the separator to at least partially open, and enables the liquid ink and the salt solution to be combined to form a mixture.

The present invention provides a two-component printable conductive composition comprising, as separate components, a metallic component comprising a high melting point (HMP) metal or metal alloy powder having a mean particle size below about 15 μm; and a fluxing component comprising an organic acid and an organic solvent. The organic acid is characterized by having at least two carboxylic groups and a first logarithmic acid dissociation constant (p K.sub.a1) of at most about 4. These two components are manufactured and stored separately and are mixed together shortly before the combined conductive composition is used for printing. Further provided is a kit comprising the two-component composition, wherein the metallic component and the fluxing component are disposed in separate containers. The present 10 invention further provides a method for deposition and patterning of the two-component composition, comprising: mixing the metallic component with the fluxing component; and applying the obtained mixture to an insulating substrate.
