problems with magnetic striping on ektachrome 64T

Post by **Juergen** » Sat Feb 04, 2006 6:30 pm

Two readers of schmalfilm magazine phoned me and told me that the magnetic striping is not possible with their s8 film E64T. They both used different processing labs, so it looks like it is a problem of the film stock itself (too much silicone/polysiloxane?). Is there anybody who already tried to get a magnetic striping on the E64T?

nobody with any experience?

not yet got my films back from processing but cant you simply test the glue on the 64 film to verify its charachterisics and at the same time do the same with some k40?

if you splice a k40 piece + an e64 piece for a test that should give the answer?
start with k40 supposed to work ok.

Well,

I haven't sound striped any of my 64T films yet but splicing them to K40 or Ekta 7240 wasn't a problem; projected it several times, no broken splicings.
As a sidenote, I had my film processed at Super8 Reversal Lab in Holland.

Regards,

Alex

This is facinating . . . What in the world are we talking about here? Adding the sound stripe ourselves to a silent stock? How does one do that? Tell me everything! (Or point me to a post.)

I've once bought a home-striper for post-striping in 2003 (thinking I could use it for pre-striping) and sold it in 2005, both on eBay.

You'll need a sound striper like this one:
http://www.super8cinema.com/sound_striping.html
(There are smaler ones, too. They have been produced by Hama, Weberling, Juwel, ... .)
Most of them simply glue a small tape onto the film (e.g. see "Tonspur und Tonspurkleber" here: http://www.wittner-kinotechnik.de/katal ... d_s8mm.php ). Some of the machines even do some "milling" before glueing the tape.

Here's some more info:

Here's an eBay-auction with such a "home striping unit" (in this case only the manual is sold, but it has a photo of the device):

Mine was about as bis as a cigar box, a wooden one made by Juwel.

I use to make my own sound striping with a Juwel machine.
It is difficult to obtain a good result with K40 or Plus X (, but it is possible.

I do not have try with 64T !!
If it is impossible , it will be for me the sadest new about this stock.

I had a chat with Nick Maltezos from EVT Magneticstoday and asked him about striping 64T. His basic answer was 'If it can be cement spliced, it can be laminate striped. But, if there is a problem, then it can be paste striped.'

Yesterday evening I have partly successfully sound striped about 70 meters of E64T with my "Juwel" machine.

No problem with the main track (0,8 mm) , but impossible with the
smaller one (0.45mm).

I have tried three times for the 0.45 mm : impossible.
I think the issue comes more from my device and my "know how", than
from the film itself.

It is very difficult to obtain a good second track with K40 too.

However , I have noticed that cement splicing on E64T was a little bit less
resistant that on K40 or Plux X.

I have projected the sound stripped E64 film , three times and the main track seems to be strongly spliced.

I will record the sound on this evening.

I think there is too much sylicon on the film.
Before to stripe, try to clean the film with trichloroethylene. It's a very common clothes cleaner, used as a dry cleaning solvent.

is trichloroethylene still avail in italy?

it was banned here 20 years ago.

Pure (anhydrous) isopropyl alcohol is a suitable film cleaner. All camera films have some level of lubricant built in to optimize film transport in cameras.
