I have used layered shaders for this in the past and came to this solution in frustration. It seemed there was always some part of the shader that didn't work correctly and made the material w/ the graphics look different than the one without. When I separated the materials onto different objects that problem was solved and this problem was created.

I've thought that interference between the two objects was likely and if I move them apart then that does eliminate the problem, but also makes the graphics look like they are floating above the panel. HOWEVER, I can also change the focal length of the camera which solves it but limits views I can render. I've attached the same view of the same model w/ only the focal length of the camera adjusted to show what I mean.
