THE IMPORTANCE OF MASTERING AND LACQUER CUTTING
When planning to release music on vinyl, think about hiring your own lacquer cutter.
Lacquer mastering is not only the final stage of the mastering process, but also the first and most delicate step in the vinyl manufacturing one.
During the cutting process, an audio recording is transformed into grooves on the surface of a lacquer disc via a lathe machine. Therefore this procedure plays an essential part regarding sound quality and overall clarity and volume levels.
In other words, transferring your pre-master files to a lacquer is an extremely crucial process and has in fact a major influence on how your vinyl record will sound.
That is why it is so important to have a dedicated engineer design the sound and cut the lacquers to truly ensure you end up with a high quality product and are fully satisfied.
THE LACQUER CUTTING PROCESS
It all starts with a visual inspection of the disc to verify the flatness. The condition of the stylus is also checked. At the same time, the lathe machine brings the stylus to a controlled uniform temperature.
During the whole process, the microscope is used to control not only the groove, but also the smoothness of the cut, the depth and the spaces between the grooves.
To conclude, the depth of cut, associated with the width of the groove, is set by the radius of the reproduction stylus tip and the signal level used during recording.
