Quiex...what exactly is this method of vinyl pressing?

I am not sure about the method of Quiex pressing, but I have been told that the Quiex pressings are "first run" pressings on very high quality vinyl. I recall that most, if not all of my Quiex pressings, were promotional releases. Also, most of my Quiex pressings are translucent when held up to a light. similar to some half-speeds.

The translucency has nothing to do with Quiex. Vinyl is translucent by nature and people just color it to varying degrees.

*virgin* vinyl is translucent. mfsl and quiex lp's were pressed on virgin vinyl. hold a mfsl lp up to a strong light source. you can see through it. now try the same with a "typical" pressing. you can't see through it 'cause it's made of inferior, not virgin, vinyl. this has nothing to do with "coloring." in fact, most colored records (not opaqely colored) are pressed on virgin vinyl. -cfb
