Vinyl Record Glossary: 26 Vinyl Pressing Terms Every Artist Should Know
If you're new to pressing vinyl, it can feel like everyone suddenly speaks a different language.
RPM. DMM. Stampers. Gatefolds. Obi strips.
The good news? Once you understand the basics, the terminology starts to make sense. This glossary explains some of the most common vinyl pressing terms in plain English, whether you're pressing your first record or simply curious about how records are made.
What do 33 RPM and 45 RPM mean?
RPM (Revolutions Per Minute)
RPM refers to how fast a record spins on a turntable.
33⅓ RPM – Longer runtime, standard for most albums.
45 RPM – Better potential fidelity with less available playing time.
| Feature | 33⅓ RPM | 45 RPM |
|---|---|---|
| Runtime | Longer | Shorter |
| Potential Fidelity | Excellent | Higher potential fidelity |
| Groove Spacing | Tighter | Wider |
| Best For | Albums and longer EPs | Singles, short EPs, and audiophile releases |
| Most Common Use | 12" albums | 7" singles and premium 12" releases |
7" Record
Traditionally used for singles, promotional releases, or short-form projects.
Optimal: Up to 3:30 min per side
Standard:3:30–4:30 min per side
Maximum:4:30–5:00 min per side
10" Record
A less common format, often used for EPs and specialty releases.

What is vinyl mastering?
Vinyl Mastering
Vinyl mastering prepares music specifically for pressing. Audio mastered for streaming isn't always optimized for a physical record, so factors like dynamics, sequencing, and frequency balance are carefully reviewed before manufacturing.
Dynamic Range
The difference between the quietest and loudest parts of a recording. Vinyl generally rewards dynamic, balanced masters.
Sibilance
Harsh "S" and "T" sounds that can become exaggerated during vinyl playback if they aren't properly managed.
What is DMM?
DMM (Direct Metal Mastering)
A process that cuts audio directly into a metal disc instead of lacquer. Some engineers prefer DMM for its precision and consistency.
Lacquer
The traditional master disc used before creating metal stampers.
Stamper
The precision metal tool that presses the grooves into every record. Every project requires its own custom stampers before production begins.
Test Pressing
A small pre-production run used to verify that the approved master has translated correctly before full manufacturing begins.
Dead Wax (Runout Groove)
The blank area between the last song and the center label. Collectors often find matrix numbers, signatures, or hidden messages here.
What are my packaging options for a vinyl record?
Jacket with Spine
The industry standard for most vinyl releases. A printed jacket with a spine provides room for album information and makes your record easy to identify on a shelf.
Gatefold Jacket
A jacket that opens like a book, offering additional space for artwork, lyrics, liner notes, photography, or storytelling. A popular choice for full-length albums and deluxe editions.
J-Fold Jacket
A premium folding jacket that wraps around the record with an extended interior panel. J-folds offer a unique presentation while using less material than a traditional gatefold.
Euro Sleeve
A lightweight single-pocket sleeve without a spine. Euro sleeves are an economical option for singles, EPs, and budget-conscious releases while still providing a clean, professional presentation.
Obi Strip
A decorative paper band wrapped around the outside of a jacket. Originally used on Japanese releases, obi strips have become a popular feature on premium collector editions.
Poly Sleeve
A protective sleeve used to help preserve either the record or the jacket. At Object Permanence Records, every record is packaged in a resealable outer poly sleeve.
Does colored vinyl sound different than black vinyl?
Color Vinyl
Records pressed in colors other than black. Modern colored vinyl can sound excellent when manufactured correctly, though black vinyl remains the industry standard for consistency.
Marbled Vinyl
Marbled vinyl blends two or more colors together to create flowing, organic patterns throughout the record. Every record is unique, making marbled vinyl a popular choice for limited editions.
Splatter Vinyl
Splatter vinyl is created by placing contrasting pieces of colored vinyl onto the puck before pressing, producing bold, one-of-a-kind patterns. No two records look exactly alike, so artists should expect natural variation throughout the pressing. The more complex the color effect, the greater the variation in appearance from copy to copy.
Picture Disc
A record with artwork embedded inside the vinyl itself. Picture discs are typically chosen for visual impact and collectability rather than maximum audio performance.
| Vinyl Type | Appearance | Visual Consistency | Audio Performance | Best For |
|---|---|---|---|---|
| Black | Classic and timeless | Most consistent | Excellent | Any release |
| Solid Color | Clean, bold color | Generally consistent | Excellent | Branding and limited editions |
| Marbled | Flowing, blended patterns | Natural variation between copies | Excellent | Distinctive special editions |
| Splatter | Bold, contrasting patterns | Greatest variation between copies | Excellent | Highly visual collector editions |
| Picture Disc | Artwork embedded in the record | Highly consistent | Generally lower fidelity | Display pieces and collector editions |
Do I need a UPC barcode for my vinyl record?
UPC (Universal Product Code)
If you plan to sell your record through retail stores, distributors, or many online marketplaces, you'll likely need a UPC barcode.
If you're only selling records at shows or directly through your own website, you may not need one.
Object Permanence Records can generate and assign an official UPC barcode for your release, making it ready for wholesale distribution and retail sales.
How do I price my vinyl record?
MSRP (Manufacturer's Suggested Retail Price)
A common starting point is to price your record at 2.5–4× your total landed cost, depending on your audience, packaging, and edition size.
For example:
Landed Cost: $12 per record → Retail Price: $30–40
Landed Cost: $18 per record → Retail Price: $45–60
Limited editions, specialty vinyl, and premium packaging often support higher retail prices.
Wholesale Pricing
If you're selling through record stores, those retailers typically purchase your records at approximately 50% of the retail price.
For example:
| Your Cost | Retail Price | Wholesale Price | Approx. Profit |
|---|---|---|---|
| $12 | $30 | $15 | ~$3 wholesale / ~$18 direct sale |
| $15 | $35 | $17.50 | ~$2.50 wholesale / ~$20 direct sale |
| $18 | $45 | $22.50 | ~$4.50 wholesale / ~$27 direct sale |
Selling directly to fans—through your website, at concerts, or at merch tables—typically generates the highest profit per record, while wholesale pricing allows you to reach a much broader audience through independent record stores.
Landed Cost
Your true cost per record after manufacturing, packaging, shipping, and related expenses.
Final Thoughts
Vinyl has more than a century of history, and with that history comes a language all its own.
Fortunately, once you know the basics, terms like DMM, RPM, stampers, and gatefolds become much less intimidating.
