Dye-Sub vs. Double-Shot: How to Choose the Best Keycaps in 2026

9 abr 2026

The Quick Answer: If you want legends that never fade and support RGB shine-through, Double-shot keycaps are the industry standard. If you prefer a smooth, matte finish with intricate designs on PBT plastic, Dye-sublimation (Dye-sub) is the superior choice.

How to Make Keycaps: The Two Leading Methods

Understanding how to make keycaps is essential for any enthusiast looking to build a high-end custom keyboard. The manufacturing process determines not only the price but the sound, feel, and longevity of your build.

1. Double-Shot Injection Molding

Double-shot keycaps are created using a complex two-stage process. First, the legend (the letter or symbol) is molded from one piece of plastic. Then, a second layer of plastic is injected around it to form the keycap body.

Result: The legend is literally part of the structure. It cannot be "rubbed off" because it goes all the way through the cap.

2. Dye-Sublimation (Dye-Sub)

This method uses heat to stain the plastic. Specialized ink is turned into gas at high temperatures and infused into the pores of PBT plastic.

Result: The ink becomes part of the material. While very durable, it doesn't allow for translucent legends, making it less ideal for heavy RGB users.
