A process for forming paint panel color standards in which a multiplicity of panels are painted and marked with a man/machine readable ID number; the improvement used with this process is as follows: (1) electronically determining the ID number of each panel and measuring each panel color coordinate values and feeding this information to a computer which establishes a criteria for various panel quality standards; (2) sorting the panels by electronically determining panel ID number and feeding the number to the computer which signals a robot to place the panel with a group of panels having the same quality standard.

DETAILED DESCRIPTION This is a process for forming paint panel color standards in which a multiplicity of panels are each coated with a paint and dried and each panel is marked with a separate identification (ID) number; the improvement that is used with this process is as follows: (1) the (ID) number of each of the panels is electronically determined by a readout device and color coordinate values of each panel are measured using a color measuring instrument such as a colorimeter or spectrophotometer and an electromechanical robot for movement of panels from the readout device to color measuring instrument; the ID number and the color coordinate values for each panel, are fed to a computer which assimilates the values and establishes a criteria based on these values for various panel quality standard categories; (2) the panels then are sorted using an electromechanical robot to move the panels to a readout device that electronically reads the panel ID number and feeds the ID number to the computer which determines the quality standard category of the panel and feeds this information to the robot which then places the panels with a group of panels that are within the same quality standard category.
