Abstract
A method of jet-printing smooth micro-scale features is presented. The desired feature prior to being printed is masked by various decimation filters and the decimation is performed at various pitches. The subsequently printed image is then scanned and analyzed to determine the roughness of the lines. The optimum decimation pitch is determined by the feature that exhibits the least amount of droplet spreading and has the lowest edge roughness. The optimum decimation pitch may also be calculated from the material properties and the dynamics of fluids.
