When shopping for mechanical keyboard keycaps, you will often see terms such as PBT, ABS, double-shot, dye-sublimation, and reverse dye-sub.
These terms may look like different types of keycaps, but they actually describe two separate things. If you are still deciding between the two main materials, read our PBT vs ABS keycaps guide first.
This means that comparing “PBT vs double-shot” is not entirely accurate. More useful comparisons include:
- PBT double-shot vs PBT dye-sub
- PBT double-shot vs ABS double-shot
- Dye-sub vs UV-printed keycaps
Quick Answer: Should You Choose Double-Shot or Dye-Sub Keycaps?
If you do not want to study the different manufacturing processes, choose according to what you need from your keycaps.
Quick guide:
For sharp, long-lasting legends, choose double-shot keycaps.
For legends that allow RGB light to shine through, choose shine-through double-shot keycaps.
For anime artwork, illustrations, or detailed themes, choose PBT dye-sub keycaps.
For light-colored legends on a dark background, consider reverse dye-sub keycaps.
In simple terms, double-shot is best for crisp legends and RGB shine-through, while dye-sub is better for detailed artwork and colorful themes.
Both processes can produce highly durable keycaps. One is not automatically more premium than the other.
What Are Double-Shot Keycaps?
Double-shot PBT keycaps use two separate pieces of plastic to form the keycap body and its legend.
Unlike printed legends, the letters and symbols are not simply applied to the surface. They are physically molded into the keycap.
As a result, the legends are extremely difficult to wear away, even after years of regular typing or gaming.
Advantages of Double-Shot Keycaps
- Highly durable legends that will not easily fade
- Sharp and consistent lettering
- Excellent for simple, high-contrast color combinations
- Can be made with shine-through legends
- Suitable for gaming, office work, and frequent typing
Disadvantages of Double-Shot Keycaps
Double-shot molding requires more complex molds and manufacturing processes, so production costs are usually higher.
It is also less suitable for:
- Large anime illustrations
- Detailed multicolor artwork
- Continuous designs across several keys
- Complex gradients
In general, double-shot molding is best for legend-focused designs rather than highly detailed illustrations.
What Are Dye-Sub Keycaps?
Dye-sublimation, often shortened to dye-sub, uses heat and pressure to transfer dye into the surface of a keycap.
Because the dye enters the material instead of remaining as a surface layer, the legends and designs are more resistant to wear than ordinary printed legends.
Dye-sublimation is most commonly used on PBT keycaps because PBT can withstand the high temperatures required during production.
Why Do Themed Keycaps Often Use Dye-Sublimation?
Dye-sublimation offers greater design flexibility and can reproduce:
- Anime characters and animal illustrations
- Multiple colors
- Artwork that continues across several keys
- Small decorative details
- Complex themed designs
For this reason, anime keycaps, cat keycaps, botanical keycaps, and other artistic sets are often better suited to PBT dye-sublimation.
Disadvantages of Dye-Sub Keycaps
Standard dye-sub legends are generally not shine-through.
Poorly manufactured dye-sub keycaps may also have:
- Blurry or uneven legends
- Misaligned designs
- Noticeable color differences between keys
- Slightly warped spacebars or other long keys
When choosing dye-sub keycaps, check the legend clarity, print alignment, color consistency, and straightness of the longer keys.
What Are Reverse Dye-Sub Keycaps?
Standard dye-sublimation works best when applying dark legends to lighter-colored keycaps.
When a design requires light legends on a dark background, manufacturers may use reverse dye-sublimation.
Instead of printing a light-colored legend directly onto a dark keycap, the process leaves the legend area undyed and applies color to the surrounding surface.
Reverse dye-sub is suitable for:
- Dark-colored keycap sets
- Light legends on dark backgrounds
- Detailed multicolor illustrations
- Color combinations that standard dye-sub cannot easily produce
Because reverse dye-sub covers a larger surface area, it requires more careful control of temperature, color, and alignment.
Double-Shot vs Dye-Sub Keycaps: Key Differences
| Feature | Double-Shot | Dye-Sub |
|---|---|---|
| Production method | Two pieces of plastic are molded together | Dye enters the keycap surface through heat |
| Common materials | ABS, PBT, or mixed materials | Primarily PBT |
| Legend durability | Extremely high | Very high |
| Complex artwork | Limited | Excellent |
| RGB shine-through | Possible | Usually unavailable |
| Common styles | Minimalist, retro, gaming, and RGB | Anime, cute, artistic, and themed |
Is Double-Shot More Durable Than Dye-Sub?
From a structural perspective, double-shot legends have an advantage in wear resistance.
Because the legend is made from a separate piece of plastic, it cannot simply rub off like a surface-printed design.
However, this does not mean that dye-sub keycaps are not durable.
With high-quality dye-sublimation, the dye enters the surface of the PBT material. It does not sit on top like ordinary ink, so the legends can remain clear for many years.
Are All Double-Shot Keycaps Shine-Through?
No.
Double-shot only means that two pieces of plastic are used to form the keycap. It does not mean that the legend is made from transparent material.
If you want RGB light to shine through the legends, check whether the product is described as:
- Shine-Through
- Backlit
- Translucent Legends
- RGB Compatible
If RGB lighting is important to your setup, browse our shine-through keycaps and confirm that the product description specifically mentions translucent or backlit legends.
The direction of your keyboard’s LEDs can also affect brightness. On a south-facing LED keyboard, top-positioned legends may not appear as bright as they do on a north-facing LED keyboard.
PBT vs ABS Double-Shot Keycaps
Double-shot describes the manufacturing process, not the material. Double-shot keycaps can be made from PBT, ABS, or a combination of materials.
Choose PBT Double-Shot Keycaps If You Prefer:
- Better resistance to developing surface shine
- A dry or slightly textured surface
- A deeper and more substantial sound
- Keycaps suitable for frequent typing and long-term use
Choose ABS Double-Shot Keycaps If You Prefer:
- Bright and vivid colors
- Sharp, well-defined legends
- A smoother surface
- A brighter and crisper typing sound
Do Double-Shot and Dye-Sub Keycaps Sound Different?
They can sound different, but the legend manufacturing process is not the only factor.
Keycap sound is also affected by:
- ABS or PBT material
- Keycap wall thickness
- Keycap profile and height
- Switch type
- Keyboard plate material
- Internal case foam
- Keyboard mounting style and case construction
In general, thicker PBT keycaps may produce a deeper and fuller sound, while thinner ABS keycaps often sound brighter and crisper.
However, you should not assume that double-shot keycaps always sound better or that dye-sub keycaps always sound muted. Material, thickness, and keycap profile usually have a greater effect than the legend process.
Which Keycap Process Is Best for Your Keyboard?
1. RGB Gaming Keyboards
Choose shine-through double-shot keycaps.
If you want a stronger lighting effect, you can also consider pudding keycaps, side-lit keycaps, translucent PC keycaps, or fully transparent keycaps.
2. Anime, Cat, and Illustrated Keycaps
Choose PBT dye-sub keycaps.
Dye-sublimation can reproduce more colors, small details, and artwork that continues across multiple keys, making it ideal for strongly themed keycap sets.
3. Dark-Themed Keycaps
Choose reverse dye-sub for detailed artwork or double-shot for simple, sharply defined legends.
4. Office Work and Frequent Typing
Consider either:
- PBT double-shot keycaps
- High-quality PBT dye-sub keycaps
Both options provide excellent durability. You should also consider surface texture, keycap thickness, and profile.
Are UV-Printed Keycaps Worth Buying?
UV printing applies ink to the surface of a keycap and then cures it using ultraviolet light.
Its main advantages include:
- Support for detailed and colorful designs
- Compatibility with several keycap materials
- Suitability for transparent or translucent keycaps
- Flexible production with relatively low mold costs
The main disadvantage is that the design still sits on the keycap’s surface. With frequent use, UV-printed legends and artwork may wear faster than double-shot or high-quality dye-sub designs.
How Can You Check Keycap Quality?
Do not judge a keycap set only by whether its product title says “double-shot” or “dye-sub.” The process explains how the keycaps were made, but it does not guarantee quality.
What to Check on Double-Shot Keycaps
- Sharp and well-defined legend edges
- Consistent legend thickness
- Clean bonding between the two plastic components
- Even keycap wall thickness
- No obvious missing plastic or molding defects
- Consistent brightness on shine-through legends
What to Check on Dye-Sub Keycaps
- No blurry, doubled, or shadowed legends
- Correct artwork alignment
- Consistent colors across the keycap set
- Even coloring across large printed areas
- No visible heat-related deformation
- Straight spacebars and other long keys
Frequently Asked Questions
Do Dye-Sub Keycaps Fade?
High-quality dye-sub designs penetrate the surface of the PBT material, so they do not peel or wear away as easily as ordinary surface printing.
Do Double-Shot Keycap Legends Wear Off?
Under normal use, they do not. Double-shot legends are part of the keycap’s physical structure. However, the surrounding surface may still become smooth or shiny after long-term use.
Are All PBT Keycaps Dye-Sub?
No. PBT keycaps can use dye-sublimation, double-shot molding, UV printing, laser engraving, and other legend processes.
Are All Double-Shot Keycaps Made From PBT?
No. Double-shot keycaps can be made from PBT, ABS, or a combination of materials.
Do Dye-Sub Keycaps Support RGB Lighting?
RGB lighting can still appear around and between the keycaps, but standard dye-sub legends usually do not allow light to shine directly through them.
Are Double-Shot Keycaps Better Than Dye-Sub Keycaps?
Not in every situation. Double-shot is better for sharp legends and shine-through effects, while dye-sub is better for detailed artwork and multicolor themes. The better option depends on the design and how you intend to use the keyboard.
Final Verdict: Which Should You Choose?
If you want sharp, highly durable legends or need RGB light to shine through the characters, choose double-shot keycaps.
If you prefer anime designs, illustrations, gradients, or colorful themes, PBT dye-sub keycaps are usually the better choice.
If you want light legends on a dark-colored keycap set, consider reverse dye-sub keycaps.
