A method for designing a magnetic plate allowing magnetic particles contained in magnetic ink distributed at different densities includes estimating a distribution of the magnetic particles allowing the magnetic ink to be spread, estimating forms of magnetic field applying the magnetic force to the magnetic particles in order for the magnetic ink to be spread in a desired magnetic printing pattern within the printing layer, obtaining adjustment factors of the magnetic plate corresponding to the estimated forms of the magnetic field by using a model for which deep learning or machine learning has been performed using design conditions including at least one of an upper surface structure of the magnetic plate and a magnetization property of the magnetic plate and obtaining a parameter for the magnetic plate configured to form the magnetic printing pattern based on the obtained adjustment factors.
