The invention provides an amplitude-modulation screening method, which comprises the step of forming a threshold value matrix used for amplitude-modulation screening by regular-hexagon lattice points. In the embodiment of the invention, an amplitude-modulation screening device is provided. The amplitude-modulation screening device comprises a matrix module used for forming the threshold value matrix used for amplitude-modulation screening by regular-hexagon lattice points. Because the amplitude-modulation screening method and the amplitude-modulation screening method device, which are provided by the embodiment of the invention, adopt the regular-hexagon lattice points to form the threshold value matrix, the problem of the lattice points in the prior art is overcome, and the effect on improving the printing quality is achieved.
