I sent Nick (EVT) asking if EVT can strip my E100D, 64T and K40.

His answer is "We can stripe all the types of film mentioned but only apply a liquid (paste) magnetic tracks."

What does it mean?

Posted by Martin Jones (Member # 1163) on May 07, 2011, 08:47 AM:

It means that the track is "painted" on a liquid containing the magnetic particles, instead of gluing a very narrow tape to the film.
This is because some film bases, including polyester, will not accept a glued stripe; paste stripe adheres to all of them and is probably(?) easier to apply consistently.

Posted by Maurizio Di Cintio (Member # 144) on May 07, 2011, 08:49 AM:

It means they don't use a tape purposedly cut to fit the limited space available for soundtracks on S/8 film, but they use a magnetic paste that is applied with a very special machine; this way the film itself constitutes the base for the magnetic track. This was the way prestripe film stocks were manufactured. The striper features a drying section to make it possible fast evaporation of the solvents needed to keep the paste at a creamy, semi-liquid state during the operation; once done the film is wound onto reels and is ready for recording.

This type of track will not come off by accident (as may be the case with laminated tape) but tends to be a little coarser to the heads. Just a little bit though and, hey after all Derann too used this method to stripe their releases (actually it was the only suitable method for poly).

Hello Winbert
Could you give me the address of EVT in the UK.
A phone number would also help. Thanks.

Hi Keith
Many thanks for EVT address and phone number. Regards.

Is it only able to strip on processed films? or able to do it on unexposed film? [Confused]

Posted by Graham Sinden (Member # 431) on May 07, 2011, 06:17 PM:

The reason EVT now only apply paste stripe is because they've run out of the laminate stripe, and this cant be obtained anymore.

Does it mean that the pasted strip becomes one part of the film? (like painting a wall).

So based on your experience which one gives better result, pasted or laminated strip?

thanks

yes

I've heard that paste stripe is more abrasive on sound heads, but if that's true then we are doomed anyway: that's how Derann has always striped their films.

It would be pretty hard to show five random films out of my own collection and not have two or three be Deranns.

Posted by Greg Marshall (Member # 1268) on May 11, 2011, 06:00 PM:

I'm about to have my scope print of 'Grease' re-recorded for stereo sound. It is my understanding that the quality you get on reproduction from the paste stripes vs. laminated (brown mag) is less superior. It depends on the print, I guess. Lance Alspaugh is going to do the job for me, but we have an understanding that the quality of the tracks may not allow for a 'booming' re-record. Fingers crossed.

Posted by Larry Arpin (Member # 744) on May 12, 2011, 12:42 AM:

Lance recorded my T2 print that had the grey Derann stripe and it turned out great. The original sound was so bad it was hard to understand what they were saying. I think their record machine was going bad. Those machines are very old.

Posted by Winbert Hutahaean (Member # 58) on May 12, 2011, 09:45 AM:

With this paste strip, (in terms of material stock) does it mean that we do not worry about the future of stripping?

ps: I don't really worry about the sound quality or abrasive thing, since this is only for my home movies.

Posted by Lee Mannering (Member # 728) on May 17, 2011, 08:29 AM:

Graham. I still have a good stock of the original 600ft Cresta laminate stripe, both bal & main.

Winbert. Make 100% certain your films are suitable for Paste. In the 80's I had large runs paste striped and it came off, caused head clog and made the print unusable. It also left me with a long cleanup job on the projector!

Posted by Graham Sinden (Member # 431) on May 17, 2011, 04:11 PM:

Lee, I also have some laminate stripe but mabye EVT dont anymore.

Not sure if its true but this is what Graham Murray told me. I will find out myself when I use them later in the year.

Nice to see you at the BFCC, shame we didnt get a good chance to chat. Hopefully see you next time.

Why there are two different opinions here?

Is the material used now is different with the 1980s?

Posted by Lee Mannering (Member # 728) on May 18, 2011, 06:36 AM:

Winbert. The prints I had paste striped were we found out later not able to take a paste stripe. EVT had a go at re paste striping them (over striping) but the type of film was not suitable or perhaps a combination of the liquid paste type was to blame as well. Laminate for me on Acetate film has always been the best and all my own home movies have Laminate applied with some dating back to the 1970’s. This stripe is still in good shape and on the films by the way. [Smile]

Great news! I heard from Lance Alspaugh this evening regarding the stereo remix for my scope print of Grease, with the mag paste tracks. The tracks are good and the re-record is a success! Thanks, Lance!

Posted by Greg Marshall (Member # 1268) on May 23, 2011, 06:03 PM:

Just previewed my Grease print. Excellent stereo remix from Lance Alspaugh. I highly recommend his work!
