Scanning electron microscopy works very well for imaging papers and 
other such cellulosic products and their coatings.
Also, the paper (etc.) can be "fractured" in liquid nitrogen to produce 
high quality edges to image the inner layers of the paper (etc.), and 
the coating layers. Cutting tends to smear the surface over the cut edge 
- this is more of an issue with coated papers.
