A method for inspecting golf balls is disclosed. An imager such as a camera captures a spectral image of the golf ball. The spectral image is captured line-by-line as the golf ball rotates. The lines are then packed together to form a three-dimensional spectral image of the golf ball showing full spectral information for every pixel. The resultant three-dimensional spectral image is then analyzed, such as using a pattern matching or threshold analysis tool. If a golf ball passes the inspection, it is permitted to advance in the processing. If the golf ball does not pass the inspection, it may be diverted. This inspection system is capable of detecting very subtle color differences, so the system is particularly applicable for use in inspecting primer coat coverage.
