How does toner particle size affect print sharpness?
In laser printing, toner particle size is a crucial factor determining print sharpness and image detail. Toner is not simply "black powder," but a functional material with precisely controlled particle size and distribution. 1. Finer particles result in finer images. Smaller, more uniform toner particles adhere more precisely to the photosensitive drum surface, creating finer text edges and smoother image transitions. This is especially critical for printing small text or high-resolution images. 2. Particle distribution affects uniformity. Not only average particle size, but also uniform particle distribution is equally important. Excessive particle size variation can lead to uneven development, increased background gray, or unstable black levels. 3. Overly fine particles […]
