The invention belongs to the technical field of packaging and printing, and particularly relates to a method and a system for automatic trapping. The trapping object into a simple color, get trapping boundary; then the ink dot and brightness based on the way of trapping on both sides of the border color meets the conditions of trapping judgment, through regional analysis, the connection to the trapping boundary; the formation of trapping area shape, filled with ink and light trapping area. The invention overcomes the defects of the existing technology in the trapping region independently, defects of connection effect is not good, to improve the overall visual effect of printing.
