Greetings,

This mode was taken from modes-3.0.mf:

I find this definition far too dark.  It seems to me that plain values of 0
to blacker and fillin work perfectly with values of o_correction in the
range of .6 to .8;  however, I am *not* a typographer or anything similar,
so please take my opinions with a grain of salt.  I ended up using the
values for mode "stylewriter", provided by Andrew Trevorrow <akt@kagi.com>
in his OzTeX distribution:

% stylewriter mode added by Andrew Trevorrow for OzTeX users.
% All parameters (except pixels_per_inch) are the same as the
% laserwriter mode (= cx) so that PK files can be shared by both
% types of printers.

mode_def sw =                           % Apple StyleWriter
  mode_param (pixels_per_inch, 360);
  mode_param (blacker, 0);
  mode_param (fillin, .2);
  mode_param (o_correction, .6);
  mode_common_setup_;
enddef;
stylewriter := sw;

The output of modetest.tex seems reasonable enough.
