A key consideration in lasering a plaque award is the amount of detail there is in any graphics used. I have a few city seals and logos that have so many small details that I laser them at 1,200 DPI. The lowest I laser at is 400 DPI; I find I get a cleaner result at 600. When lasering at a higher resolution, you may be able to lower your power level. I find some plate colors such as blue plates work best with two passes.
