I wonder why the interpositives used for the GOUT was so rough by the way? Shouldn't they look cleaner than the theatrical prints, being two (is this correct?) generations closer to the negative? Just look at all those glue marks between almost each shot shift, especially in ESB. It's like they let some kid cut and glue it together.

They were old and battered from overuse I guess. New IP's should instead have been produced, but they probably thought they were good enough back then. Around the same time a restoration of the films was under way, but we all know how that turned out.

The splice glue you see in ESB is indeed ugly in many places, but it was seen on theatrical prints as well.
