We describe the formation of deposition patterns that are observed in many different experiments where a three-phase contact line of a volatile nanoparticle suspension or polymer solution recedes. A dynamical
model based on a long-wave approximation predicts the deposition of irregular and regular line patterns
due to self-organized pinning-depinning cycles corresponding to a stick-slip motion of the contact line.
We analyze how the line pattern properties depend on the evaporation rate and solute concentration.
