Re: [APML] Medium Format TP...worth messing with?

["Bobby Middleton" <bobm@koyote.com>]

The bleedthrough was a problem for the last few rolls I had hypered which
was over a year ago. I have not gotten back to any hypered 120 TP since,
but someone mentioned it not long ago on APML I believe.
This was a problem and a hot topic on APML 4-5 years ago. Kodak had the
problem IIRC because of a dye (was it paper?) change. Kodak fixed the
problem  with a reformulation and everything was OK for 2-3 years. But when
this appeared about 1 year ago I did some checking with Kodak. They claimed
no changes but I was skeptical.
I was able to salvage the shots with use of the clone tool in Photoshop but
that's a poor solution.
You might check this set of older APML archives:

Here's an image of M45 that shows the problem:
