Based on the study of definition of printing production intent with JDF, and the completed study of printing process planning modeling based on polychromatic sets theory, the solution of printing process searching was proposed in this paper. First, the JDF document which includes the Product Node was parsed to acquire the “requirements of printing production in terms of client”. Second, printing order was analyzed to acquire the “requirements of printing production in terms of non-client”. At last, the printing process was calculated with the polychromatic-sets-theory based printing process search algorithm. The printing process searching prototype software was developed by Java, and a print job was analyzed to verify the solution.
