The analysis of modern methods of the digital screening of images is carried out. The methods of obtaining the screening images with amplitude-modulated, frequency-modulated and amplitude-modulated--frequency-modulated structures are represented. The method of screening on the principle of the distribution error is described in details. The comparative analysis of the most popular algorithms of this class with using the elementwise processing of the image is realized. It is described the algorithm of the block distribution error, which provides the generating of the pattern free moir. The results of the screening are represented.
