ABSTRACT:
A pen plotter capable of producing large 3-D stereo plots is described. The operating principles is based on micro-polarizer arrays and spatial multiplexing. Because of the vector based plotting and the continuous transfer of the ink from the pen to the paper, previous methods for making 3-D stereo printing cannot be used. Instead, a new "pixel skipping pen" and paper combination are devised which exploit the fact that water and oil do not mix. Dedicating oil-based inks for plotting the right perspectives on hydrophobic coating on the plotter paper, while water-based inks for plotting the left perspectives on hydrophilic coating, makes it possible to achieve 3-D stereo plotting with automatic registration on a single component 3-D plotting paper. Two other kinds of 3-D plotting papers are devised which use two and three specially treated sheets that are registered with pins.
