Colored vinyl runs are a p.i.t.a. for any pressing plant, as it requires cleaning out the extruder of the press before and after the run, meaning more downtime.
transparent vinyls, sound diferent in a good way.
all transparents ive heard sound more depth or something.
black is not always better,
ive heard 1 record that the PVC was so "low quality" that in 3 plays the record got noise, but had great sound.
i think that the softer the PVC the better highs you can stamp, but the easy to wornout at play.
but that was only 1 ofcourse, exeption to the rule maybe.
was one of franky bones LP, but cant remember the name, i think is where studio 54 song is.
all others were "normal".
i dont like heavy LPs, dont feel they sound better, just heavyer. i like light maleable records. most solid color vinyls sound strange
, less dynamic, more noise. but most transparent color vinyls sound ok.
the transparent yellow with black stripes, also sound interesting, leopard pattern.
the solid red with black, sounded strange.
never heard a picture disc.
PVC quality does affect the outcome, i dont like solid "crystalized" PVC that breaks easy when they hit the floor.
also when some paper gets stuck in the PVC and the disc gets affected in a bad way, so sad.
PVC that sounds Good, melts easy with sun light, if you play them under a sunny day at the end of the song they look like this: The Persistence of Memory - Wikipedia, the free encyclopedia
