A 3-colour ink jet plotter for computer graphics

  • Boris Smeds


A new plotter for hard copy colour display of digital computer outputs has been developed. The plotter uses three intensity modulated ink jets with the colours red, yellow and blue, which plot the information on a normal A 4 paper (210×297 mm) fastened to a rotating drum. The ink jets are individually controlled from a magnetic tape unit which is loaded with a tape prepared by the computer. The total plotting time is 85 seconds independent of the complexity of the picture to be plotted. The total information contents plotted in one 85 second run is 3.7·106 bits.
