Abstract

A method manufactures solid ink sticks by forming a solid ink paste and injecting the paste into a mold having internal cavities. The method includes generating a solid ink paste, injecting a portion of the paste under pressure into a cooled mold having at least two separable shells that form ink stick cavities, and separating the shells of the cooled mold to release solid ink sticks from the ink stick cavities.
