According to one aspect of the invention, a system for handling microelectronic dies is provided. The apparatus includes a body having a channel, a string passing through the channel, and a mechanism for moving the string a predetermined first distance to deploy a first of the medical appliances and for moving the string a predetermined second distance to deploy a second of the medical appliances. The voltage of the first break point is equal to or smaller than that of the second break point. The method also includes calculating and storing a communication FTE according to the types of human resources. The method comprises obtaining image data for a single color channel and generating, from the image data, multi-level screen data describing, for each of the first and second inks, the ink mark volume to be made by the array of printhead nozzles at each screen location.
