The invention relates to the technical field of control adjustment, in particular to a control method and system for preparing invisible double anti-counterfeit labels for corrugated cartons. The method comprises the steps of obtaining a monitoring image of an ink surface in a process of preparing an invisible double anti-counterfeit label of a corrugated carton, and obtaining a fluorescent brightness uniform evaluation value of each region in each frame of monitoring image according to a difference of brightness values of pixel points in each region and pixel points around the pixel points in each frame of monitoring image; and acquiring a ray corresponding to each frame of monitoring image in each preset direction, and obtaining a mixture grain uniformity characterization value corresponding to each frame of monitoring image according to the brightness values of pixel points in areas corresponding to nodes in every two preset directions and the fluorescent brightness uniformity evaluation value, so as to de
