Abstract

Computer-generated line drawings are most commonly produced by pen plotters, and quality depends primarily on the equipment used. The main controlling parameters are accuracy and precision, but the plotter mechanism may impose a stepped or ragged structure on lines. Thus while they may remain within tolerance, their visual quality is affected. Pens for plotters must be chosen for reliable operation under conditions of mechanical handling, usually without continuous supervision. Users can influence the quality of their drawings by appropriate choice of drawing procedure, particularly by ensuring that the result depends on the precision rather than the accuracy of the plotter.
