Here is how to identify a vinyl pressing from photos: photograph the label and the deadwax, the smooth ring between the last groove and the label, then read the catalogue number and the matrix code etched or stamped there, and match both against the versions list for that album on Discogs. When every detail agrees, you have found your pressing.

Two copies of the same album can look identical from the front and still be completely different records. One might be a first pressing from the year of release; the other a reissue pressed forty years later from a different master, at a different plant, on different vinyl. They share a title and a cover. Almost everything else can differ — including the sound and the price. The good news is that the evidence is printed or etched on the record itself, and a handful of clear photographs is usually enough to read it. This guide works through the photo reality: how to photograph faint deadwax etchings, how to read a record matrix number, how to find your exact pressing on Discogs, and how to tell a first pressing from a reissue — with an honest note at the end about what the evidence cannot prove.

This guide is about the pressing — which exact manufactured version of a record you hold — not about identifying the music itself. If the album itself is the mystery, our guide to identifying what is in a picture covers the general photo-identification method first. And if you only have the cover art and do not yet know which album it is, start with our guide to finding a song or album from its cover art — pressing identification begins once you know the album.

What is a vinyl pressing, exactly?

A pressing is one specific manufactured run of a record: the same album, pressed at one plant, from one set of stampers, at one point in time.

That definition matters because it explains why collectors treat pressings as separate objects. When an album is reissued, the label usually cuts a new lacquer, sends it to a (possibly different) plant, and presses a new run. The new run gets its own catalogue number, its own label design for its era, and its own matrix codes in the deadwax. A reissue is therefore not a copy of the first pressing in any sense a collector cares about — it is a different release that happens to contain the same music.

It is worth saying up front that “first pressing” is a slippery phrase, and honest guides say so. For many popular albums, the very first run was spread across several plants in the same week, each pressing slightly different stampers. So the goal here is not to win an argument about who pressed the truest first copy. It is to identify your specific release accurately — so your catalogue is correct, you know what you have, and you do not pay first-pressing money for a later copy.

Pressing identification is a detective exercise built on agreement between clues. No single clue settles it on its own. A catalogue number narrows the field; the deadwax narrows it further; the label design and the sleeve confirm the era; the Discogs match ties it all together. When the clues agree, you have your answer. When they disagree, one of them is being misread — and the deadwax is usually the one telling the truth.

How to identify a vinyl pressing from photos: the four clues in order

Work through the clues in this order, photographing each one as you go. The order matters: it moves from the easiest check to the most decisive one, so you stop as soon as the answer is clear.

Catalogue number. Every release carries a catalogue number, the label’s own reference for that specific issue of the record. You will find it on the label, usually near the spindle hole, and on the sleeve, typically on the spine and the back cover. When an album is reissued, it almost always gets a new catalogue number, or a recognisable variant of the old one. Two copies with different catalogue numbers are, by definition, different releases. Photograph the label straight on and the sleeve spine, and note the number down before you do anything else.
Deadwax matrix code. The smooth ring between the last groove and the label carries etched or stamped codes — the matrix information. This is the closest thing a record has to a fingerprint, and it is the clue that separates versions which share a catalogue number. The next section explains how to read it.
Label design and wording. A record label’s artwork is not fixed. Logos, fonts, rim text and colour schemes change over the years, and a given design belongs to a specific era. Record label variations by year are well documented by collectors, so a label design that postdates the album’s original release year points to a later issue. Check whether the label reads “STEREO” or “MONO”, look for promo markings such as “Demonstration, Not For Sale”, and read the small print — rights-society text and address lines get revised over time and can pin down an era.
Sleeve and small print. The packaging carries dating clues too. Barcodes are the clearest: they did not appear on records until the late 1970s and were not widespread until the mid-1980s, so a barcode on an album originally released before then is a strong sign you are holding a later pressing or a reissue. Country-of-manufacture text tells you where the record was pressed. Modern reissues tend to announce themselves on hype stickers and back covers with phrases like “180-gram”, “remastered” or “limited edition”.

The same field-by-field matching discipline works for other collectables too — our guide to identifying a coin, stamp or collectible from a photo uses the same catalogue-number approach, because the principle is identical: one object, several near-identical versions, and the answer hidden in small printed details.

How do you read a record matrix number?

The deadwax, also called the runout or the matrix area, is the smooth ring of vinyl between the last groove and the label, and the codes etched or stamped into it are the most precise evidence a record carries.

Start by getting the light right, because the codes are shallow and often faint. Hold the record almost flat and tilt it under a single light source so the beam rakes low across the surface — a small torch or your phone’s torch held at a steep angle works far better than overhead room light, because the raised and recessed characters catch the raking beam and become readable. Photograph the deadwax under that light, and do both sides separately: side A and side B usually carry different matrix strings, and the punctuation is part of the identifier.

Then write down exactly what you see, including every letter, number, space, dot and stray symbol. A transcription that drops a space or a dash is a transcription that will match the wrong release on Discogs. Deadwax runout codes explained in one line: the string is a compact record of who cut the master, which lacquer it was, and where the disc was pressed.

Inside the deadwax you may find several distinct things:

The matrix number itself, which ties the disc to a specific master and side. It often echoes the catalogue number with a side indicator added. Many matrix strings also carry a small suffix — a digit or a letter — that records which lacquer cut or take was used. As a rough rule, a lower cut number points to an earlier lacquer, so a side stamped “1” or “1A” was cut before one stamped “4”. This is one of the clues that separates an early copy from a later repress made from a fresh lacquer.
Pressing-plant and stamper codes, which tell you where the record was physically made. Plants used recognisable marks: “MO” for Monarch, “PR” or “PRC” for Presswell, “CTH” for the Columbia plant at Terre Haute, and “SS” for Specialty Records Corporation, among many others. The same album pressed at two plants in the same month counts as two different versions on Discogs.
Mastering engineer marks, which are the runout’s most quietly famous detail. Some engineers signed their work, and collectors learned the initials. “RL” is Robert Ludwig, “BG” is Bernie Grundman, and “TJ” is Ted Jensen. The hand-etched “Porky” or the phrase “A Porky Prime Cut” is George Peckham. Spotting a known engineer can date a pressing and, for certain records, raise its value, because particular cuts developed a reputation among listeners.
How the characters were made. Hand-etched, slightly irregular scratching is common on older and earlier pressings. Clean, uniform, machine-stamped characters point towards a later pressing or a modern reissue. It is a soft signal, not proof, but it is a useful first impression.

Worked example: reading a real runout

Here is how the pieces come together, using a runout string that collectors cite as the classic example. Take a copy of Led Zeppelin II whose side A deadwax reads “ST-A-691671-A RL SS” — the exact string unpacked in Analog’s guide to pressings, and the reason this example is worth studying is that every part of it means something. “ST-A-691671-A” is the matrix number itself: the label and side prefix, the master number, and the side letter. “RL” is the engineer, Robert Ludwig. “SS” is the plant, Specialty Records Corporation. Vinyl Run’s guide to identifying pressings notes that Ludwig’s “RL” cut of Led Zeppelin II is among the most sought-after pressings of that album — which is exactly why the initials matter and why forgers and careless sellers both trade on them.

Your copy will read differently; the string above belongs to one specific version, and that is the point. You do not need to decode every record this thoroughly. You need to copy the full string accurately so you can match it later — and when a seller’s listing shows a deadwax photo you can read, you can do this check before you pay a penny.

How to photograph a record label and deadwax so the codes are readable

Most failed identifications are photography failures, not knowledge failures. The codes are there; the photo just does not show them. Follow these steps and the identification usually becomes straightforward.

Photograph the label straight on. Hold the phone directly above the label, parallel to the record, in soft daylight or under a single lamp. Include the whole label: catalogue number, logo, side indicator, track list and small print. A tilted or cropped label photo hides exactly the details you need.
Photograph the deadwax with raking light. Tilt the record under a torch held low and almost flat to the surface, and shoot while the etched characters catch the light. Take two or three shots at slightly different angles — one angle reads one half of the string, another reads the rest.
Photograph both sides. Side A and side B carry different matrix strings. A listing that shows only one side is half an identification, and the missing side is often the one that separates two versions.
Add the sleeve spine and back cover. The catalogue number on the spine, the barcode (or its absence), the “Made in” line and any hype sticker all date the release. Photograph a record label for identification purposes and you need the label; photograph the sleeve too and you can cross-check it.
Avoid flash glare. Direct flash washes out shallow etchings and turns the vinyl into a mirror. Raking light from the side is the whole technique — if the characters are not visible on your screen, move the light, not the camera.
Check the photo before you put the record away. Zoom in on the deadwax shot on your phone. If you cannot read every character, retake it now. A blurry matrix photo taken at a record fair is useless once you are home.

If you are buying online and the seller’s photos are too poor to read, ask for exactly these shots before you bid — a straight label photo and a raking-light deadwax photo of each side. A seller who cannot or will not provide them is telling you something. And if you want to check whether the seller’s own photo has been lifted from another listing, run it through our free reverse image search tool first: a photo that appears on several listings under different sellers is a warning sign worth knowing about before you pay.

How to find your exact pressing on Discogs

Discogs is where the clues come together. Discogs catalogues releases at the level of the individual pressing: every version of an album is listed separately, each with its own catalogue number, country, year, label and matrix details. That structure is exactly what makes it the right tool for this job — you are not searching for the album, you are searching for your copy.

Find the album’s master page. Search Discogs for the artist and album title, then open the master release page, which groups every version of that album together.
Open the list of versions. The master page shows how many versions exist — sometimes a handful, sometimes well over a hundred for a famous album.
Match what you have, field by field. Work down the list comparing your catalogue number, the matrix strings you transcribed from each side of the deadwax, the country, the label variant, and the presence or absence of a barcode. Pay particular attention to the runout fields, since two versions that look identical on catalogue number alone are often told apart only by their matrix strings. When everything agrees, that version is your pressing.
Filter ruthlessly. Use the version list’s country and year filters to cut a long list down. A UK copy and a US copy of the same album are different versions, and filtering by country first saves most of the work.
Check the images. Discogs version pages carry user-submitted photos of the label and sleeve. Compare your label photo against them — the logo variant, the rim text and the colour should match your copy exactly.

If a record predates Discogs-era cataloguing or is poorly documented there, 45worlds is a useful second reference, especially for older 78s, 45s and LPs where collectors have logged label and runout detail. Its homepage lists more than 266,000 vinyl album records alongside its 7-inch singles catalogue, so it is worth checking before you conclude a record is undocumented. Between the two databases, most commercially released records can be matched.

Discogs also shows prices, and reading them properly takes a little practice. The prices shown on a listing are asking prices, not real prices: a seller can ask £80 for a pressing that usually sells for £22. What counts is the sales history — the “Last Sold” figure and the median price for that exact version. Condition matters just as much: the grading scale runs from Mint down to Good, and in practice most interesting used records sit between Very Good Plus, meaning light signs of play with near-perfect sound, and Very Good, meaning some surface noise but still very playable. The classic trap is overgrading — what a seller calls Near Mint is often a decent Very Good Plus, and their Very Good Plus is sometimes an honest Very Good. When you buy online, always ask for photos of the matrix and of the surface under raking light before you commit.

First pressing vs reissue: how to tell — and when to stop claiming

If the one question you care about is “is my record a first pressing”, a few signals get you most of the way. Use the table below as a quick read, then weigh the signals together — no single one is decisive on its own.

Signal	Points to an early copy	Points to a later pressing or reissue
Barcode	No barcode on an album released before the late 1970s	Barcode present on a pre-1980s album
Packaging wording	No reissue language anywhere on the sleeve	“Remastered”, “180-gram” or “reissue” printed on the packaging
Label design	Label design from the album’s original release era	Label design that postdates the original release year
Matrix cut number	Low cut number such as 1 or 1A	Higher cut number such as 4, or clean modern machine-stamped codes
Catalogue number	Original catalogue number from the release year	A new catalogue number, or a recognisable variant of the old one
Etching style	Hand-etched, slightly irregular characters	Uniform machine-stamped characters

It is worth being honest about the limits here, because overclaiming is how collectors lose money and credibility. A matrix number by itself is not proof of a first pressing. Early matrix codes were reused, repressed and copied across plants, and a low cut number tells you a lacquer was cut early, not that your particular disc came off the press first. Treat the deadwax as strong evidence to be weighed alongside the label, the sleeve and the Discogs match, rather than as a verdict on its own. Identification is the accumulation of agreeing clues, not a single magic code. When the evidence does not establish an early pressing, do not claim one — describe the copy accurately as the version you matched, and let the buyer or the catalogue decide what that is worth.

Two related points are worth knowing. First, a first pressing does not automatically mean the best sound: the physical condition of a record always matters more than its generation, and a clean later pressing can sound better than a worn original. Second, promo copies deserve a mention. You recognise them by a white label or a “Promotional Copy, Not For Sale” stamp; they were sent to radio stations and journalists before the official release, pressed early and often with care, in limited numbers — but radio stations in the 1970s were not kind to their styluses, so condition can be terrible. A cut corner or a drill hole in the sleeve, by contrast, usually marks deleted stock sold off cheap, not a promo. Japanese pressings are a category of their own: known for strict plants, clean vinyl and careful packaging, often with an obi strip — the paper band wrapped around the sleeve — they are considered by many collectors the best available versions of a large number of rock, soul and jazz albums.

Crate digging for pressings uses the same eye as any other kind of collecting. Our guide to identifying vintage and thrift store finds from a photo covers the wider habit — furniture, clothing and ceramics — and the discipline is the same: photograph the marks, read them literally, and match them against a database before you decide what something is worth.

FAQs

Is my record a first pressing?

Match your copy on Discogs using its catalogue number, both deadwax matrix strings, country and label variant. If every field agrees with a version from the album’s release year, you likely have an early pressing. A barcode on a pre-1980s album, a “remastered” sticker, or a later label design all point the other way. No single clue proves it alone.

What does the writing in the deadwax mean?

The deadwax holds the matrix number, which ties the disc to a specific master and side, plus optional plant codes and mastering engineer initials. “RL” means Robert Ludwig cut the lacquer, “SS” means Specialty Records Corporation pressed it, and a low suffix such as 1A marks an early lacquer. Transcribe every character exactly, including spaces.

Can I identify a vinyl pressing from a photo alone?

Yes, if the photos show the label straight on and both deadwax sides clearly under raking light. Those two shots carry nearly all the evidence. If the etchings are unreadable in the photo, ask the seller for closer raking-light shots before you buy. A blurry matrix photo cannot identify anything, and guessing from it is how mistakes happen.

Why do two copies of the same album sell for different prices on Discogs?

Because they are different pressings in different conditions. Discogs lists each version separately, and prices follow the exact version plus its grade. Listing prices are asking prices, not sold prices — check the “Last Sold” history and median for your version. One sale abroad does not set the value of a worn copy at a flea market.
