It really depends on what he's doing. For CNC drilling a 60 thou error 
would be intolerable. Not only would his holes be way off but he would 
miss via pads completely. While linear compensation can be helpful for 
dimensional errors that aren't entirely linear, laser artwork is a 
real PIA when it comes to CNC work. You're better off using an inkjet.
