Abstract
A multi-step process promotes an even distribution of glitter particles while providing a uniform texture and appearance even with respect to non-planar and volumetric surfaces. A pneumatic spray is preferably used to urge the particles against the article and into a selectably applied adhesive while rotating and vibrating the article utilizing a suitable electromechanical transducer. The surface is then wiped to knock down particles which may have been standing on edge, preferably using an air spray at an acute angle relative to the surface. With the particles substantially flat against the surface, the adhesive is cured, and any excess particles are blown off. Following this, a passivating overcoat may be applied.
