  We present a comprehensive study of nanoparticle deposition from drying of
colloidal droplets. By means of lattice Boltzmann modeling and theoretical
analysis, various deposition patterns, including mountain-like, uniform and
coffee ring, as well as un-/symmetrical multiring/mountain-like patterns are
achieved. The ratio of nanoparticles deposited at droplet peripheries and
center is proposed to quantify different patterns. Its value is controlled by
the competition between the capillary flow and nanoparticle diffusion, leading
to a linear dependence on an effective P\'eclet number, across over three
orders of magnitude. Remarkably, the final deposition pattern can be predicted
based on material properties only.
