White mesh in stock: 60, 86, 110, 160, 180. Dyed mesh: 180, 230, 305, 355. Dyed costs more than white. White mesh refracts light during the screen exposure process whereas dyed mesh absorbs light. Dyed mesh is better for half tones, thin lines and fine details. Such details might not wash out with white mesh due to exposure from refracted light.
