"Print through" heard on CD has to be from something on the master tape. Pre- (and also post-) echo on vinyl comes from one groove wall deforming the one next to it, and is always one disk revolution away from the "real" signal. You can get it on records that were cut sloppily, as Steve said. But there can be other contributing factors. I have read that if the lacquer is not plated soon after cutting you can get some from the lacquer itself shifting a bit. I also observe that certain types of "pressings" (I am thinking of the Columbia polystyrene type here) can be more prone to it than others -- I have two otherwise identical-looking copies of a couple of singles, one on vinyl and the other on the polystyrene, and the polystyrene one has much more pre/post-echo. (Not all Polystyrenes do, but it seems you need to leave a little more space, or maybe cut a deeper groove or something. Probably Steve would know.) Also, if you play a record with a heavy pickup, you can actually make the groove echo much worse. I have observed this in a slightly insane experiment I did a couple of years ago, mounting an old BSR TC8S crystal cartridge in a Technics turntable and playing some throwaway records with it. I had two identical pressings, both new (radio station freebies of, you should pardon my opinion, garbage metal music). Pre-TC8S they sounded identical. After one single playing (I think it was at the specified tracking force of 7 grams) the one played with the TC8S had *much* more pre-echo. I first noticed the phenomenon myself back around 1965, on my first Parlophone mono copy of Rubber Soul. I heard echo after the end of Think For Yourself and then pre-echo before The Word. In those days I was using a BSR changer fitted with (yup!) the seemingly omnipresent (in Britain) TC8. Not a TC8S (stereo) but a TC8H (mono, high output), which was the least compliant, spec'd at 10 grams.
