There are several factors to consider when addressing the issue of non-impact printer resolution. One will find differences between the imaging resolution and the final output resolution, and most assuradly differences exist between the advertised and actual resolution of many of these systems. Beyond that some of the technical factors that effect the resolution of a system in-clude:
. Scan Line Density
. Spot Size
. Energy Profile
. Symmetry of Imaging
Generally speaking, the user of graphic arts equipment, is best advised to view output to determine the degree of acceptable quality.
