Analysis of Coated Paper

Surface Structure Visualization

The properties of a paper coating can depend critically on the micron and submicron structure of the paper coating The AFM is ideal for visualizing the sub micron structure of paper coatings. Such images easily show the particle size and shape of the components of the paper coating. Figure 4 illustrates the AFM images of an Opti-Gloss PCC aragonite coating before and after printing. The change in surface texture is readily visualized.
