ABSTRACT:
A method of operating a system for jetting phase change ink comprises 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 the contacting the first volume of ink with a second volume of similarly jetted ink in a liquid state so that the two volumes are superimposed. Thereafter, the second volume of ink is caused to undergo a liquid to solid transition by lowering its temperature.
