The problem with noisy picture discs concerned only one type of disc,
and then only one side of those discs. There are several ways picture
discs were made. If the disc used a central core printed on both sides
with a blob of clear vinyl placed under and over it in the press, the
result will be a very quiet disc but slightly fuzzy pictures on both
sides with a clear rim. Another style used a preformed black vinyl core
with a printed sheet on both sides and just a thin layer of clear vinyl
on one side and a thicker layer on the other. The thin layer had a
clearer picture but more noise. The rims will be black.

There is a possibility that colored and clear vinyl pressings are using
virgin vinyl because any impurities will be visible. The only reused
vinyl must be the exact same color. It could be edge-trims from early
pressings in the batch mixed in as the pressing continues. Black
pressings can use older reused vinyl without visual notice.
I have also noticed that mixed-color pressings are equally quiet as the
stylus passes over each different color. This also includes the splash
shellac pressings on Pathe in the mid-20s with black and red shellac,
and the Aeolian-Vocalion pressings that had 4 to 6 colors. The
different colored shellac did not deteriorate or wear at different
rates. This proves that the 35 cent red Perfects were as good as the
identical 75 cent Pathe laterals.
