My understanding is that Linotronic now makes printers capable of
printing on film to over 4000 dpi.  This would be about 6 micron dot
size.  However, 2540 dpi works out to 10 micron dot size, so if the
linotronic printer did not give you that quality of result you may want
to check other aspects of the system (i.e., does your program really
generate accurate data in the print file, and is the printer in good
condition?).

Subject: Better resolution for desktop publishing masks


        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.
