I  have  a LaTeX document that uses fonts cmmi5 and cmmi7. I found that the
characters  are  too  thin when printed on our TI postscript laser printer.
The local sys. admin. suggested adding the lines 

	mag:=0.3;
	mode:=ti;

to the cmmi5.mf and cmmi7.mf files and run the program cmmf on them. He has
had  success in making other fonts more substantial this way. For the cmmi5
font, the head of my files looks like this: 

% Computer Modern Math Italic 5 point
if unknown cmbase: input cmbase fi

font_identifier:="CMMI"; font_size 5pt#;
mag:=0.3;
mode:=ti;

u#:=12.5/36pt#;      % unit width
etc.

For the cmmi7 :

% Computer Modern Math Italic 7 point
if unknown cmbase: input cmbase fi

font_identifier:="CMMI"; font_size 7pt#;
mag:=0.3;
mode:=ti;

u#:=15.5/36pt#;      % unit width
etc.

I got the following log files of cmmi5 :

and for cmmi7, the log file is :

Both  fonts compiles error free without my additions. Could someone tell me
how  to  recompile  these  font  so  that the lines are darker? None of the
people here know much about metafont. Thanks in advance.
