Abstract
A calligraphic writing system of the type including an x-y plotter, a writing pen and a digital computer that controls the movement of the pen relative to the writing bed of the plotter. The system self-aligns the writing pen and items on the bed being written, and permits a number of items to be correctly positioned on the writing bed and to be written during a single cycle. The pen draws positioning marks on the writing bed, thereby insuring that the item(s) to be written on and the pen are properly aligned relative to each other. In embodiments in which a plurality of items (all of which may or may not be the same) may be written in one cycle, the computer determines how many sets can be placed on the writing bed at once, and draws positioning marks for each item of each complete set that will so fit.
