Say goodbye to monotonic, faded legends as you can bring the town with dye sublimation keycaps

Dye sublimation keycaps have been around and become a sought-after choice for years thanks to their eye-catching legends, customization options, and overall durability.

If you are new to this keycap printing method, we will walk you through the captivating world of dye sublimation keycaps and add some pizzazz to your daily clicks!

1. What are Dye Sub Keycaps?

Dye-sub, short for dye sublimation, is the method of printing legends on paper with special ink before fusing them into keycaps using heat. The word "sublimation" describes the process where a solid directly turns into a gas without melting and becoming a liquid first (much like dry ice).

Once the dye becomes a gas, it is able to penetrate into the plastic and change the color on a molecular level using high temperatures.

This ingenious printing process can strengthen the resistance of dye-sub keycaps to wear and tear and makes it almost impossible to fade over time.

Dye-sublimation was all the rage in the 1980s and has remained its reliability for producing keycaps, especially for custom and artisan keycap sets until now. Instead of simply printing a single letter or number, dye-sublimation allows for intricate designs and rich vibrant colors with smooth gradients.

What makes dye sublimation process surpass other common keycaps printing methods like laser etching, or pad printing is its high-resolution printing. It can create crystal-clear legends with no roughness or raised edges even if the top layer gets rubbed since there is no solid ink left on the top of the keycap.

Let’s picture it!

  • Standard top printed keycaps: The ink is directly applied on top and once it wears off, the only thing left is a blank keycap. This is in line with the cheap price it has.
  • Double shot keycaps: Multiple plastics in different colors are molded and fused to create keycaps with long-lasting legends. They are not cheap, of course. Yet, customization ability is not the top.
  • Dye sub keycaps: The ink is able to penetrate into the plastic so the legends will still be visible even if you rub off some of the top layers.

If you are curious about other types of keycaps, the following summary of the keycaps world will broaden your horizons.

You see, dye sub keycaps strike the balance between durability, customization and cost. It’s no surprise why keyboard wizards now increasingly value the high personalization level of dye sub keycaps as they can jump into the unique world of art that these keycaps offer to unleash creativity and showcase their styles.

2. Manufacturing Process of Dye Sublimation Keycaps

Let's go on a mesmerizing tour of the dye sublimation keycap manufacturing process that turns plain keycaps into colorful canvases of expression:

Step 1: Prepare keycap design

The adventure starts with preparing the design of artwork that will be printed on the keycaps’ surface using computer software. Manufacturers create the desired legends, symbols, or designs that will be infused onto the keycap surface.

Step 2: Keycap mold injection

If you have no keycaps ready, you need to prepare a keycap mold and fill it with the material. Since the process involves a high melting point, the dye sublimation keycaps typically use high-quality thermoplastic like PBT. ABS-made versions do exist although they are uncommon.

The mold is then heated and pressurized to form the keycap. This initial injection molding creates the basic shape of the keycap.

Step 3: Print keycap design

Once the design is ready, it is printed onto a special transfer paper using a dye sublimation printer. The design is reversed on the transfer paper before being sublimated into the keycap's surface.

Step 4: Sublimation

The printed transfer paper is carefully placed on the coated keycap. Make sure the keycap precisely aligns with the legend. The keycap and transfer paper assembly are firmly clamped together.

Step 5: Applying heat and pressure

While the keycap is tightly clamped and the transfer paper is sublimated at a high temperature and pressure, typically in a heat press machine. The magic begins! Heat causes the dye sublimation ink on the transfer paper to transform directly from a liquid state to a gas.

Step 6: Infusing the design

The polyester coating on the surface of the keycap is penetrated by the ink when it turns gaseous. Instead of being a printed layer on top, the design is permanently infused into the keycap. And voilà! Vibrant, unbreakable legends were born!

Step 7: Cooling and finish

It takes some time for the keycap to cool down once the sublimation process is finished. After it has cooled, the transfer paper is carefully removed, leaving behind a vivid and long-lasting legend that won't fade or wear off with use.

Follow along as we break into a small dye sub keycap factory in China to better understand the process of creating awe-inspiring artistry behind designing, printing, and infusing life into these technicolor keyboard wonders.

3. Are Dye sub keycaps good?

3.1. Durability

Although dye-sub printing on keycaps may give the misconception that its endurance is subpar, it really has the second-highest level of durability of any printing method to date, right behind double-shot.

Unlike the cheap standard top printed keycaps, dye sub ones undergo a special heat treatment process that engraves the legend onto the keycap that won't fade, wear off, or become shiny after countless hours of typing and gaming.

Furthermore, most dye sub keycaps are often made from high-quality PBT, which is resistant to wear, chemicals, and heat. This lengthens their lifespan overall and guarantees they can withstand the rigors of daily use.

Is PBT really durable? Is there anything else better? Take a moment to read our research on what is the best keycaps material.

However, we cannot promise the legend can last forever. Chances are, it may only withstand long periods of use as the whole top surface of the keycap starts to wear.

Put this aside, you will not want to miss a pretty long-lasting keycap set without breaking the bank as you pay for a double shot set, right?

3.2. Design

It should come as no surprise that the boundless customization possibilities of dye sublimation keycaps gather like-minded keyboard enthusiasts in one place.

Just trade a little durability, and you will get a one-of-a-kind aesthetic.

The dye sub process allows for rich and consistent colors, making your keycaps pop with life. Even the most intricate designs cannot make it difficult. But the fun doesn't stop there! Dye sub keycaps come in a variety of shapes and sizes, allowing you to mix and match different profiles to suit your tastes.

In short, these magical dye sublimation keycaps are like a blank canvas waiting for your creative touch. Whether you're a gamer, an artist, or a keyboard fan, dye sublimation keycaps always give you the power to design a keyboard that is uniquely yours.

3.3. Typing feel

Unlike rubber keycaps providing a unique tactile experience, dye sub-keycaps offer a smooth-as-butter feel. In contrast to what you typically experience the bumpy top printed keycaps, you won't even feel the legend itself. Indeed, dye sub keycap legends are injected into the keycap material, giving them a consistent and smooth surface.

Moreover, the PBT material used in dye sublimation keycaps is denser and more rigid, giving them a sturdy and solid feel under the fingertips. Plus, the keycaps features a slightly textured surface to deliver a pleasant tactile sensation. This texture can help improve grip and reduce the likelihood of fingers slipping during extended typing sessions.

3.4. Sound

Dye sub keycaps produce a "thock" sound that is more subdued and solid sounding than other keycaps. This is because the PBT material used in dye sublimation keycaps is denser and less resonant than ABS material, making the sound often deeper and less high-pitched.

Wondering why PBT is better than ABS in producing a more pleasant sound. Take some minutes to read our in-depth comparison between these two keycap materials.

The texture of the keycaps can also influence the sound. The slightly textured surface of dye sublimation keycaps can reduce key wobble and contribute to a more stable and consistent sound when typing.

3.5. Price

Dye sublimation keycaps have a mid-range price tag that falls between the cheaper regular printed or laser-etched keycaps and expensive double shot ones.

Dye sub keycaps maintain a compromise between durability and high standards of color accuracy, and overall craftsmanship, which may make them seem a touch pricy to some people, but it is understandable why.

Keycaps with sophisticated designs may also command a higher price, as they had undergone the design process with rich and complex graphics. Limited-edition or custom-made sets may also come at a premium due to their exclusivity and unique appeal.

If you want to add something unique to your keyboard for years to come, dye sublimation keycaps are go-to sets that truly reflect its value.

Pros Cons
  • Refined and detailed design
  • Long-lasting legends
  • Affordable
  • Smooth touch
  • Solid and subdued typing sound
  • Only work well with PBT or high-quality ABS
  • Single color legends
  • Limited custom-designed versions
  • Premium dye sub keycaps can be more expensive

While dye sub keycaps are generally good, the “good” eventually falls down each individual’s interest. Some prioritize aesthetics, meanwhile, others simply want more durable legends without paying more bucks.

Therefore, before deciding to go for a dye sub keycap set, think about your purposes first.

Still in doubt about your decision? Take a moment to go into the secret battle between dye sub keycaps and double shot keycaps to make the winning choice.

FAQs

1. Is dye sublimation good for keycaps?

Yes. Dye sublimation is considered good for keycaps. It provides durable and vibrant designs that do not fade or wear over time.

2. Are dye sub keycaps expensive?

Not sure. The price of dye keycaps can vary depending on quality, design and availability. You can find many sets for prices ranging from $20 to $120. However, this is not a definitive answer, as there may be cheaper or more expensive options elsewhere.

3. Is dye sublimation high quality?

Yes. Dye sublimation is more premium than  other standard printing methods like pad printing. This process is favored for its superior durability and visual appeal, making it a more high-quality option for keycaps in most cases.

4. How long do dye sub keycaps last?

The exact lifespan of dye sublimation keycaps depends on the keycap quality, material and use frequency. With proper care, they can last for many years. As the legends are embedded into the keycap material itself, they will not fade, chip, or wear away for a very long period of time.

5. Do dye sublimation keycaps fade?

No. The legends are infused into the keycap material, becoming a permanent part of the keycap itself. As a result, they are less likely to fade or wear off. The only way the legend can disappear is if the keycap's whole top surface wears off when you use the keycaps forcefully.

6. Can you make your own dye sub keycaps?

Yes, surely! You can make your own dye sub keycaps at home, but it requires some specialized equipment, materials, and skills. This process may be a complex and labor-intensive process.

7. Are dye sublimation keycaps compatible with backlighting?

No. Dye sub legends are solid and do not let the light through. The dye-sublimation process is only on non-backlit keycaps made from PBT. If you want to use backlighting, you need to use keycaps with translucent or transparent legends, such as double-shot, laser-etched, or shine-through keycaps.
