How does the use of screentones (or digital equivalents) differ between manga and Western comics, and how does this impact the aesthetic?

Screentones are used extensively in manga to create shading, texture, and visual effects. They're often applied in large, solid areas to create dramatic contrasts. Western comics traditionally use screentones more sparingly, focusing on subtle gradients and textures. The heavier use of screentones in manga contributes to its distinctive, graphic aesthetic.
