Laser your file.  The strength and speed of the print will depend on your specific machine. On ours, medium speed with high power were the best settings.  Also keep in mind the number of coats you used.  The only thing to keep in mind when setting the print : laser bottom to top -  top being the side with air vacuum.  This way the vaporized paint won't re-coat already lasered areas.

Definitely avoid re-lasering a second time over. There's pretty much no way to avoid having to do this if you notice you haven't gotten all the way through the paint, but once you figure out your settings, remember them so as to avoid having to do a twice-over.
