If you were laying Vinyl on top instead of printing 3M 3200 Engineer Grade or 3M 3400 Engineer Grade Prismatic would be more cost effective than the IJ680. 3M Commercial Graphics has IJ5000 and IJ5100 that are printable if I am not mistaken. I am a bit biased with the 3M Reflectives that we use for Traffic Applications but there are alternatives out there. You could go for something like Oracal 5300 If you aren't printing, We have tested it in the past and it is a very good product that is very easy to apply to flat surfaces, I have heard nothing but good things about what Nikkalite sells as well. Then again most of my knowledge of reflectives is related to Traffic Applications and not Consumer Graphics.
