On a lark I decided to buy a bottle of Noodler's Blue Ghost and start signing my artwork in invisible ink.
Test shots:
Apologies for the cell phone images. I wrote on both coated and uncoated sections of the paper. The ink did not stain the image.
Under UV light the ink on the uncoated areas really stands out.
It is also visible to the eye on the coated sections, although much less so. The camera does not pick it up well. UV light screws with it.
