摘　　要：调频加网技术相对于传统调幅加网工艺更具优势,但这一技术在新闻纸印刷领域鲜有应用,为推广调频加网技术的应用,本研究通过设计出基于新闻纸印刷的调频网点印刷工艺测试版,制作出网点大小分别20μm、40μm、60μm的印刷样张,采用主观评价和客观评价相结合的方法对印刷样张进行分析得出基于调频网点的新闻纸印刷的实地密度、印刷相对反差(K值)以及网点扩大值等参数的最佳控制范围。Compared with the traditional amplitude screening technique,the frequency modulated screening technique is more advantageous,which is rarely utilized in the field of newspaper printing.In order to promote the application of the frequency modulated screening technique,the beta version of the newspaper printing based frequency modulated screening technique has been designed in the research.Through subjunctive evaluation and objective evaluation,analysis has been made on printing proof with dot size of 20 μm,40 μm and 60 μm to acquire the best parameter control realm of the actual density,relative printing contrast（K value） and dot gain of frequency modulated screening based newspaper printing.
