We (my 2 partners and I that have our dumb little Garage Punk record label) have an interesting (IMO) and unprecedented (for us) issue you might find interesting.
You are probably aware that CDs are comically cheap to manufacture....even for a little indie label with a modest pressing quantity, they are less than a US dollar to manufacture. CDs are one of the all-time consumer rip-offs.
Vinyl is a whole other ballgame. A label like us probably sells 3-4 times as many LPs as CDs. If it were up to us, we would only release vinyl ('cause we know CDs look sh!t and mp3s sound even more sh1t) but a) our job is to spread our bands' music as widely as possible, and b) even though we know the reality of the relative sound quality of vinyl vs. digital....who are we (old men) to tell teenagers what's cool? ;-)
Anyway....the cost to press vinyl is about 4 times more (check this out, very interesting, if you dig it find Part 2 yourself http://www.youtube.com/watch?v=xUGRRUecBik) and is far more complex than CD replication.
In brief, you give the presser the masters (digital or tape) and they provide you with a "test pressing" (apols to the many whose knowledge dwarfs mine)....a white labelled LP that you need to listen to check the sound quality and sundry details like side a/b. We were mortified a few years ago before we knew what to check so one of our top singles is the wrong way round.
We are nothing from nowhere, learning as we go along but there has never been an issue with the quality of the cut. [this is so boring I can barely finish, sorry]
Tests arrived a couple of weeks ago. My proper sound system is not here for even longer, more boring reasons.....but my flatmate has a killer, 50s/60s compact valve turntable that even has a 16 rpm option! But it's skittish so when I played a test pressing it didn't just skip.....it skated across the LP which happens to many/most modern lightweight LPs . So I went out to a local record shop that has a killer rig to play it....I played two tests, full on. No issue at all. So we told the presser to proceed.
Some of the stock LPs skip on some turntables, but not all, no logic to it. Presser is giving me sh1t, saying I didn't test the tests properly. Absolutely false.
Not very interesting, sorry.
