Method for monitoring the crystallization of at least one organic material from a liquid. The cavity is suitable for absorbing an overflow of ink, characterized in that the cavity is filled with separate grains having angles and sharp edges having dimensions that are significant compared with an apparent dimension d of the grains. A dimple can be formed on the first leg and a protrusion can be formed on the second leg opposite to the dimple on the first leg. Furthermore, the destination node may receive and deinterleave the interleaved data packets and error correction data. The brush extends from one of the first and second open ends.
