 摘 要：本論文闡述了調(diào)幅、調(diào)頻加網(wǎng)技術(shù)的歷史背景以及發(fā)展現(xiàn)狀，闡述了兩種加網(wǎng)方式的基本原理，剖析了兩種加網(wǎng)技術(shù)的優(yōu)勢(shì)和不足，探討了調(diào)頻加網(wǎng)制版工藝在高位彩色、CTP、高保真、專色印刷中的應(yīng)用，提出了開(kāi)發(fā)一種能夠結(jié)合調(diào)頻、調(diào)幅加網(wǎng)技術(shù)優(yōu)勢(shì)的加網(wǎng)方式的可行性。用調(diào)頻加網(wǎng)技術(shù)制作印刷品，測(cè)出不同網(wǎng)點(diǎn)面積率，并比較該印刷品CMYK四色版網(wǎng)點(diǎn)擴(kuò)大的程度，通過(guò)與175線調(diào)頻加網(wǎng)印刷品相關(guān)數(shù)據(jù)的比較，得出調(diào)頻加網(wǎng)技術(shù)有利于圖像階調(diào)層次的復(fù)制，有利于提高圖像清晰度的結(jié)論。

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.
