Abstract
A paint tinting system includes a plurality of colorant dispensing subsystems interconnected with a clear filler dispensing subsystem. Recipes maintained within a microprocessor control the dispensing of fixed volumes of colorant into dispensing tubes with such volumes being maintained between volumes of clear filler. Valve actuation introduces the colorant into a can of base paint, along with sufficient clear filler to assure a full measure of paint is generated. The subsystems provide for recirculation of the colorants and clear filler to assure that the same remain homogenous at the time dispensing is required.
