Embossed lathe cuts that have been recorded on polycarbonate sheets of plastic for many years since the 1980's, most definitely, have earned a bad reputation since, because they were always embossed with a tungsten carbide stylus. Many have tried over the years different techniques to improve embossing, by using, Turtle wax, furniture polish, lighter fluid, motor oil, DW40, But I don't use any of that, I emboss dry, and works great.
If recorded at a louder volume it will cause the record to skip randomly, this the average level of a microgroove LP recorded at 33-1/3 rpm. Occasionally some copies may have a few seconds of noise at random times but generally 90 percent of them will sound fine. The music on an embossed record is slightly lower in volume.
Anti-skating and tone arm counter weight adjustment is critical for a embossed lathe cut to TRACK properly.
10" and 12" Lp's, I don't recommend, because of noise build-up in the embossing process in recording long cuts of 10 minutes or more. No guarantee there will be no intermittent surface noise.
