  We studied the morphology of linear particle deposits obtained by
inkjet-printing of silica nanoparticle suspension in drying condition where
contact line depinning occurs. We show that this evaporation mode can be
obtained by adjusting the particle concentration in different solvents. For
isolated drops, deposited manually or by inkjet printing, drying induces the
formation of two concentric rings in which particles self-assemble into a
monolayer. For fused drops, our main result is that stable rivulets could be
formed by drop overlap leading, after drying, to the formation of three
parallel lines composed of a self-assembled particle monolayer. The three lines
are of homogeneous thickness with two very thin outer lines (~ 1 $\mu$m width)
and a wider central line (~ 20 $\mu$m width). We reveal how the width of the
resulting lines is influenced by drop spacing in a predictable manner for a
large experimental window knowing the drop size.
