Abstract: The paper studies on AM, FM screening technology and the development of their historical background, and analyzes the basic principles of two screening technology, advantages and disadvantages of FM screening technology in high color plate, CTP, Hi-Fi, spot-color printing applications .After exploring study, can be made to develop a combination of FM, AM screening technology advantages of the feasibility of screening methods. FM screening technology with the production of printed matter, measuring the rate of dot areas, and compare the expansion of the print outlets, relatively CMYK four-color version of the degree of dot gain and with 175 lpi of data compared with the corresponding conclusions drawn. We can get the conclusion that FM Screening technology is in favor of image-level copy of Tone curve and will help improve the image sharpness.
