RITSTIFT FOER SKRIVARE ELLER RITMASKINER

摘要

Method and apparatus for making plots and mechanical drawings having predetermined and accurately controlled line widths directly from data from computers or other suitable sources. An ink-jet writing system is mounted on a traveling carriage and relative movement between it and a receptor surface is effected. Functions of the rate of such movement in the plotting directions are determined and used to generate a corrective signal fed to the ink-jet system to adjust the amount of ink reaching the receptor surface to thus create lines of controlled widths irrespective of the rate at which this relative movement takes place. Characters or other signs and symbols may be generated using the method and apparatus of this invention.
