The sound system — Some hints concerning the sound track
The sound track
Striping for sound of SUPER 8 mm. films can be carried out throughout the whole world. Every good
photographic dealer can give you addresses of firms who undertake this work. You can also consult the
EUMIG agent in your country. You will find a list of all EUMIG agents throughout the world on the guaran-
tee card which accompanies every EUMIG MARK-S SUPER 8.
How is striping done?
1. An 0.7 mm. wide ribbon of magnetic tape is bonded onto the film.
2. A solution of iron oxide in a quick-drying liquid is sprayed along the edge of the film.
We recommend the use of films which have been striped by the first-mentioned method.
When is striping done?
1. On processing.
2. After editing.
Both methods give excellent results. We would, however, recommend the second, as this enables a con-
tinuous stripe to be added to the finally edited film, thus avoiding “drop-outs“ at the points of splicing.
Remember also that a striped film will occupy more space, so that when you send a film for striping, a
120 m. reel should contain a maximum of 105 m. of film, and a 180 m. reel should contain no more than
150 m. of film.
What is essential for good sound reproduction with striped film?
1. Exact and clean splicing.
2. Keeping the films clean (film cleaning materials, as well as anti-static cloths, are available from your
dealer). ;
3. Films should not be cleaned or treated with anti-static media before striping, as the sound stripe
might otherwise not adhere properly.
4. Dust-free film storage (preferably in cans).
5. Protection of the films against excessive drying out (use tightly closing cans, and insert a special
“film-fresh“ material, or possibly a moist piece of blotting paper).
6. Keeping sound heads clean (use o soft brush).
