What is a test pressing?
A test pressing is one of a small batch of records pressed from new stampers before a full production run, so the artist, label or mastering engineer can check the sound, track order, speed and runout etchings and approve the job. Pressing plants commonly send about five copies, usually with plain white labels. Collectors prize them because so few exist.
Where test pressings fit in
Making a record takes several steps. A mastering engineer cuts each side into a lacquer disc on a lathe. A plating plant turns the lacquer into metal parts and, eventually, stampers, the negative plates that press the vinyl. Third Man Pressing in Detroit describes the next step: the stampers go into the press, the first test pressings are checked by its own audio team, and then copies go to the artist, label or management. Production only starts once the customer approves.
If a test pressing reveals a problem in the cut, the side is cut again and new tests are made. Wikipedia's article on matrix numbers notes that each new cut gets its own test pressings for review.
How many are made
Five is a common number. Disc Makers sends five copies with orders that include test pressings, Third Man Pressing supplies five by default with more available at extra cost, and Furnace Record Pressing's FAQ refers to a batch of five. Small plants and labels sometimes make as few as three.
Runs can be bigger. In a Discogs database forum thread, one longtime contributor wrote that plants typically make about ten white-label tests, that labels can ask for 20, 50 or 100, and that labels often use the extras as promos.
What gets checked
Furnace's checklist for customers covers sound quality; the catalog number and A/B side inscriptions etched into the run-out; song order and the visual gaps between tracks; any custom runout message; and playback speed. Disc Makers adds a caveat: test pressings are a check on the pressing, not a chance to judge the mix or mastering, which should be final before the order.
Plants also tell customers not to panic over a click on one copy. If a noise appears on only one test pressing and not the others, it's isolated to that copy rather than the stamper.
Do test pressings sound better?
Not necessarily. Furnace explains that test pressings come off a brand-new stamper and that the first 30 or so records from a new stamper can be a little noisy, which is why it discards those records in production. RPM Records, a Danish plant, says an approved test pressing should sound no different from a regular copy.
The vinyl can differ, too. Disc Makers and Furnace both press tests on black vinyl, whatever color the final order is, and Furnace's 12-inch tests average 160 grams regardless of the weight ordered.
How to recognise one
Most test pressings have blank or plain white labels, sometimes with a printed "test pressing" label, a plant stamp or handwritten details. Their runout markings usually match a released version, unless that cut was rejected. Discogs only tags a release as a Test Pressing when it is clearly marked as one; otherwise, a blank-label copy is listed as a White Label, because a plain label alone can't show whether a record was a test, a promo or neither.
Don't confuse test pressings with acetates. Discogs describes acetates as coated aluminum discs, typically without runout information that matches any retail version.
Test pressing FAQ
Are test pressings valuable?
They can be, because so few exist, especially for well-known artists. Value still depends on demand: a test pressing of a record nobody wants is still a record nobody wants.
How can I tell a real test pressing from a fake?
Compare the runout markings with those on a documented retail copy. Be wary of markings that could have been added later: Discogs treats stamps, stickers and handwriting on an otherwise blank label as post-manufacture changes. Provenance, such as a known source or paperwork, adds confidence.
Is a white label the same as a test pressing?
Not always, though they are often the same object. Discogs uses White Label for any vinyl with unprinted labels and reserves Test Pressing for copies clearly marked as tests.
Why do some labels sell test pressings?
Labels can order extra tests beyond what approval needs, and some give or sell them to DJs and fans. Those copies come from the same test run, but they may not be as scarce as the name suggests.
Do test pressings come in sleeves?
Usually only plain ones. Disc Makers ships its tests in plain white inner sleeves with a generic proof label.
