I have recently used a commercial printer to make a mask on printer's
film.  He used a Linotronic printer with 2540 dpi.  The mask gave us about 25
micron resolution, which I understand is pretty typical.
        I would really like about 10 micron resolution, but our
photolithography system does not have reduction capability (only 1:1).  Does
anyone know how to get closer to 10 microns?  Try to find higher dpi
capabilities?  Commercially available reduction to make a new mask from the
existing mask?
        Any suggestions would be appreciated.
