I am working on the first module in a new N-scale model railroad layout. In this urban scene, I am using florescent paints of various types under black light to simulate neon and other lighting in night scenes.
I use printed paper in a lot of applications in my modeling - not just for business signs but highway signs, tar paper on roofs, some areas of brick and concrete, small details, etc. The unexpected problem I am having is finding any white printer paper that doesn't fluoresce under black light (it is the whiteners that are used in modern papers that fluoresce -- in fact one test to see if you have an older document in your hand is to put it under black light). Stop signs and tar paper roofs of buildings and manhole covers should NOT be glowing at night.
I am told some art supply stores sell non-fluorescent natural white papers, but I have yet to track any down. I went into the OfficeMax yesterday with a handheld black light (we all own these in Phoenix for finding scorpions in our houses at night, as they fluoresce too, but that is another story). The good news is that Homeland Security did not bust me for odd behavior, but I did not find anything that would work. I actually have some clear paint that is a UV block, but it dries glossy, so right now I am painting a layer of the block and then a layer of matte clear coat. This does not look entirely right, and is a pain to do for every item.
On the off chance one of you has an idea with this ridiculously niche bleg, fire away in the comments.
