Advantages of lacquer cutting
As a mastering engineer, I cringe when I see clients send their projects directly off to pressing plants and leave the lacquer cutting in their hands. If you hire your own lacquer cutter, you have an open line of communication with the person cutting the lacquers, which is the most important part of the vinyl manufacturing process regarding sound quality. Sending your audio straight to a vinyl pressing plant and letting them handle the lacquer cutting is essentially the equivalent of that. Transferring your digital vinyl pre-master to a lacquer is an extremely crucial process, and has a major influence on how your vinyl will sound. With most 3rd party lacquer cutters, you can order a reference lacquer to listen to with test cuts at different levels to get the most volume and quality out of your recording. Any necessary changes at this stage are costly and can significantly delay the completion of your order. For a pressing plant to take responsibility for a problem, it usually needs to be a clear mistake like using the wrong audio source, altering the song order, or something else that is factual and not opinion based. If the pressing plant is handling the lacquer cutting for you, they often cut the lacquer at more conservative levels as a quick and easy way to avoid pressing and playback issues, rather than taking the time to get the most out of your lacquer cut and really getting it dialed in. They may also blindly apply default filters to the high and low frequencies to help avoid playback issues, rather than take the time and care to dial things in as well as possible.
Cutting into lacquers is an older method of mastering for vinyl records, but still has many supporters and fans. This analogue mastering technique is widely accepted and used thanks to bigger number of lacquer cutting lathes available and the tradition of lacquer mastering through the years. Hundreds of various lathes were produced during the golden era of vinyl records between 50's and 80's and many of them are still operable. GZ still owns and uses the VMS - one of the best and most reliable lathes ever manufactured. Moreover, engineers and technicians working in GZ upgraded this lathe in , so now it can fully use advantages of the new Vinyl Visual Mastering system. The audio signal is transcribed into a master plate called lacquer through a dedicated cutting head comprised of two moving coils perpendicular to each other - one for the left and one for the right channel. Movements of both coils are transfered to a cutting stylus with a sharp triangular tip on the end. The stylus for cutting into soft lacquer is heated and is made out of saphire or ruby gems and cuts a spiral V-shaped sound groove into a nitrocelulose layer covered on an aluminium disc. Stampers for record pressing are manufactured from such mastered lacquers by a three step electroforming process in electrolytic baths. It is recommended to start these processes with already cut lacquers as soon as possible to avoid deformations of grooves caused by heat and other environmental factors.
