Chase;
I understand it is not a mainstream concept to use Ultraviolet.
HOWEVER, it reveals slight details not visible to the natural naked eye.
I find it especially useful when trying to determine lamination error as compared to Struck through. The ultraviolet will reveal variations in the level of the surface of the area in question, where a struck through will show both sides of the area are level ( in an open area of the surface, both sides being the same color ). This can suggest to me which flaw I may be seeing, as level on both side of the line indicates, or suggests a foreign item made the line, whereas if the coloring varies from each side of a line it indicates a change in level of the surface, which indicates to me the possibility that the surface is lifting on one side compared to the other.
