This picture, courtesy of a great article about how albums are physically made clears up one of the great mysteries of creating LPs, 12-inch singles and other records.

For YEARS I have always wondered how albums get those labels pressed on the album with absolutely no warping or other physical problems–even years after the pressing, the labels stay put in most cases. Now I know why.

My original theory was that it was some kind of super glue that held the record label in place, but it turns out that good pressing plants BAKE their labels before applying them to the record album. Baking the labels removes excess moisture that would cause warping or other problems. No water, no goofy labels.

Ingenious!
