I wonder if the new 3M printed plates are less sensitive to the location of the IR as the older plates with the reflective properties of them of bouncing the light back towards the source?
What I am seeing is that the more IR light/ the more "contrast" you have between the background and the numbers/letters it makes it easier to read them. Then if you have too much IR light then there is too much reflection off the good plates and makes it hard to read them. One needs a balance which by chance I think I have achieved. I will post a couple of pictures over the next day or so. Pictures are worth a thousand words.
