Abstract

Systems and methods are provided for controlling a color masterbatch feed rate in production of a manufactured part to match a color of the manufactured part to a target color by adjusting a concentration of masterbatch that is mixed with a raw material and fed into a processing machine for producing the manufactured part. Control of the color masterbatch feed rate is based on optical spectral properties of an in-line manufactured part, a known reference part having the target color, and an algorithm for calculating and adjusting the color masterbatch feed rate.
