Vertical jitter with Tri-X

[Andreas Wideroe]

I recently did a large WP3 transfer job for a client and the result was pretty good. However, quite a few of the Tri-X films showed up with little to bad vertical jitter. I've done K40 transfers later with no problems and as I said, most of the Tri-X films came out just fine.

A few weeks ago I had a conversation with Roger Evans and we touched this topic and he had also seen this on many films he receives from his customers.

I'd like to know if anyone else has experienced this and if it can be linked to last years jitter-crisis.

I suspect the problems mainly occour in other emultions than K40. I don't have anything to back me up here except my experiences, but could the thickness of the emultion, or not perfect sprocketholes or something else be the cause?

I had the same problem in summer 2000 with two (out of two) cartridges of Plus-X, which dated back to a 1997 batch.

They were shot on mi Nizo 6080 along with several K40's (both sound and silent). Of these all of the sound ones turned out perfect, but most of the silent ones had from low to bad jitter. In fact I suspected this was due to wear of film gate in the camera.

Just my contribution.

Take care.
