Bassweight excerpt: dubplates, masters and mastering

[cyrusfx]

I thought it was pretty cool to see how dubplates actually got cut...

But I have a question for you linguistic afficionados: so its true that "dubplates" are specifically masters with microscopic defects?
I always thought they were just one-off pressings.

The acetate dubplate is a faulty 14" vinyl master that has been cut down.

When you get a record mastered for vinyl the tracks are cut to a master disc, it is 14" in diameter. They have quite a stingent quality control I believe. Anything faulty is, to my knowledge, cut down and sold for use as dubplates. One off cuts for playback. Primarily they were / are used as reference discs during the mastering session, and for DJ's to use when playing out.

Hope that make sense. There are a bunch f vinyl mastering videos on YouTube. Look for ones covering the manufacturing process. I believe the 14" disc is cut 2" in, so that the master doesn't get damaged during transit.

You can't 'cut down' an acetate - it's a metal disc coated in shit.

I'm pretty sure a 12" acetate dub = a rejected 10" master lacquer.
10" acetate dub = a rejected 7" master lacquer.

I wonder what happens with all the rejected 14" lacquers which can't be used for a 12" pressing though

The things we call "vinyl" dubs, like you get at Dub Studio or whatnot, are a custom made disc from a PVC compound made specifically for dubplate cutting though.

I remember watching the whole thing last year, I wish there was still a youtube link up so I can show it to my brother.

I'm sorry, my mastering engineer who's been cutting dubs and vinyl masters for nearly 20 years and my manufacturer who has been in the field for even longer must obviously be lying to me.

A 10" master lacquer is 14"s. the master size doesn't change because the final disc is a smaller format.

Ps. Your metal disc coated in shit is, a metal disc coated in acetate, hence it being call an acetate.

I just watched the video and Jason does say "...for example, a 10 inch dubplate is a reject 7 inch master" so yeah, master lacquer size does apparently change depending on the target vinyl size.
Everyone does their thing differently though. I'm sure your boy knows his shit, I'm just going by what I've learnt from Henry @ Dub Studio, Leon @ Music House and whatever Jason just said in that video which I've pretty much forgotten already.

And 'acetate' isn't actually acetate, it's lacquer. Not a big deal though.
I'm not arguing with you anyway man, everything's blessy
