Start with a complete source package
Pressing begins before a record reaches a machine. The project needs an approved audio source, a side allocation, artwork files, label information and a packaging decision. A pressing facility may provide its own naming rules, upload method, technical form and schedule. Use those documents as the controlling specification.
Source material should be final enough to review, but the artist or label should retain a clear approval point. Replacing audio or artwork after manufacturing preparation can create rework, extra review and schedule movement.
From master to metalwork
A vinyl-specific master is transferred through a cutting stage at a high level. A cutting engineer turns the approved program into a physical groove pattern. The resulting lacquer or equivalent production medium is used to create metal parts. These parts eventually form stampers used in the press.
The terminology and exact route can differ by supplier. The useful operational point is simple: the audio is translated into a physical format, and each handoff needs a named approval or record. Keep the approved master, notes and supplier correspondence together.
Stampers and pressing
Metal parts are prepared for the pressing line. Labels, compound choices and record specifications are matched to the job. The press forms a record from heated material between the prepared stampers. This is specialist plant work; do not treat general online settings as operating instructions.
Colour, weight, finish and other options can affect preparation and inspection. Confirm what the selected supplier can manufacture before artwork and public release plans are fixed.
Cooling, trimming and inspection
After forming, the record is cooled and finished. The edge is trimmed, and the unit is checked for visible issues. Inspection can include surface appearance, label placement, edge condition and handling marks. Listening review is separate from visual inspection and should be planned as its own control.
A test pressing is useful before a full run, but it does not guarantee that every later unit will be identical. Keep approval notes specific: identify side, track, time position, audible symptom and decision. Avoid vague comments such as “sounds wrong”.
What to prepare and what to check
- Approved audio master and side sequence.
- Supplier template, specifications and delivery method.
- Label copy, catalogue reference and rights information.
- Packaging decision with quantities and assembly notes.
- Named approval owner for audio, artwork and final goods.
Before release, compare the approved reference with the physical result, confirm the package count and record any accepted variation. Coordination is the main control. The press itself is only one stage.
