Thai script is intricate, composed of loops, curves, and stems that can easily become muddled at small sizes or from a distance. The Bold weight simplifies these complexities. By thickening the strokes, the designers at PSL (Public Company Limited, a major Thai type foundry) created a font that screams to be read. It retains the elegance of the Thai alphabet but adds a layer of sturdiness that allows it to hold its own against busy backgrounds—much like a neon sign holding its own against the visual noise of a busy market street.
