摘 要:通常印刷使用黃、品紅、青和黑四種分色版和相應的油墨印刷。為了提高印刷品的質量,減少印刷色序對印刷質量的影響,從印刷圖像的階調再現、色彩再現、圖文清晰度、印刷均勻性和印刷重復率等方面出發,通過分析印刷色序的影響因素,研究不同類型的原稿和印刷工藝條件,經過分析常用的制定印刷色序的原則和方法,以及不同印刷方式下印刷色序安排,并以原稿案例的形式討論影響印刷色序的因素,提出膠印中的色序制定的方案,以利于印刷質量的提高。
關鍵詞:印刷;色彩再現;印刷色序;印刷質量
Abstract: Generally, we use the yellow, magenta, cyan and black, four color separation to print with the appropriate ink. In order to improve the printing quality and reduce the impact of the color sequence of printing on printing quality, taking those into consideration such as printed image tone reproduction, color reproduction, graphic resolution, printing uniformity and repetition rate of printing, we study different types of manuscripts and printing conditions by analyzing the factors of color sequence. Through the analysis to the common principles and methods of formulating the color sequence, and different color sequence under different printing methods, we discuss the factors which affacts the color sequence with the sample of original manuscript and propose the programs of formulating the color sequence to improve the printing quality.
