What does Resolution of an Output Device Mean?



THE MEANING OF RESOLUTION OF AN OUTPUT DEVICE IS:
Resolution of an Output Device is expressed as DPI (dots per inch) and refers to the number of laser spots per inch. It is generally considered that having output resolution of 600 DPI or above is important for attractive but achieving quality halftone reproduction relys on having much more resolution than that. A properly formed halftone dot will require a resolution many times higher than the halftone ruling. (A 150 line screen is best when output at a resolution of 2540 DPI.) This is why quality imagesetters have peak resolutions measured 3000 DPI and above.
