Abstract
A method of operating a system for jetting phase change ink by effecting a solid-to-liquid phase transition of the ink by elevating its temperature, ejecting a first volume of liquid ink towards a target, lowering the temperature of the ejected ink to cause it to solidify after contact with the target and then contacting the first volume of ink with a second volume of similarly jetted ink in a liquid state so that the second volume lies on the first volume. Thereafter, the second volume of ink is caused to undergo a liquid-to-solid transition by lowering its temperature. By this method, the height of printed material is built up.
