(1) Dithering Mode: The laser would create the image using dot patterns, which might result in a loss of fine detail and a more textured appearance.
(2) None Dithering Mode: The laser would use continuous tones, engraves solid areas based on the image's brightness, which provides a more precise representation of the original image.
None Dithering is usually more difficult to use and only performs better than Dithering under specific circumstances.
