Keycaps are an essential component of a mechanical keyboard, and the way they are printed can greatly affect the look and durability of the keyboard. In this article, we'll explore the different techniques used to print keycaps and their advantages and disadvantages.
Double shot molding is one of the most popular and durable methods of printing keycaps. In this process, two layers of plastic are molded together to form the keycap. The first layer is the base color, and the second layer is the legend or symbol that is printed on top of the keycap. This process results in legends that are more durable and resistant to fading or wearing off over time, as the legend is actually part of the keycap itself and not just a surface layer. Double shot molding is often used for keycaps with backlighting, as the light can shine through the legend, making it more visible and vibrant.
Dye sublimation is another popular technique for printing keycaps. In this process, the legend is printed onto a transfer paper using special dye-based inks. The transfer paper is then heat-pressed onto the keycap, causing the dye to penetrate the surface and become part of the keycap itself. Dye sublimation is known for producing vibrant and detailed legends that can be printed in full color, making it a popular choice for custom keycap sets and designs. However, dye sublimated legends can be more susceptible to fading over time compared to double shot molded legends.
Laser-etched keycaps are another option, in which the legend is burned into the surface of the keycap using a laser. This process results in a legend that is well-defined and precise, but it may not be as durable as double shot molded or dye sublimated legends, as the laser etching can fade over time with prolonged use.
Pad printing is another technique used to print keycaps, in which the legend is printed onto the surface of the keycap using an ink transfer pad. This process is typically used for keycaps with simple or single-color legends, as the pad printing process is not as detailed or vibrant as other printing methods.
In conclusion, the way keycaps are printed greatly affects the look, durability, and overall quality of the keyboard. When choosing keycaps, consider the type of printing technique used, as well as the design and style of the keycaps that suit your preferences. Whether you prefer double shot molded legends for durability, dye sublimated legends for vibrant full-color designs, laser-etched legends for precision, or pad printed legends for simplicity, there is a printing technique that will meet your needs and enhance your keyboard.
