The authors report measurements of the interface formed when a wet front propagates in paper by imbibition and they find anomalous roughening with exponent alpha=0.630.04. The authors also formulate an imbibition model that agrees with the experimental morphology. The main ingredient of the model is the propagation and pinning of a self-affine interface in the presence of quenched disorder, with erosion of overhangs. By relating their model to directed percolation, they find alpha≃0.63.
