A composition and method for fabricating high-density Ta\u2014Al\u2014O, Ta\u2014Si\u2014N, and W\u2014Si\u2014N sputtering targets, having particular usefulness for the sputtering of heater layers for ink jet printers. The memory and computer program code can be configured to, with the processor, cause the apparatus to illuminate one or more sensor elements with electromagnetic radiation emitted from corresponding regions of an electronic display. The binder is preferably a polymeric material which is clear and transparent.
