Abstract: At present, the printing industries of china are thinking many ways to improve print quality .This article start from optimizing the printing process. Mainly discusses the three printing process control method. Including Solid Ink Density, dot gain curve control method and G7 process control methods. The article explained the need to control the printing process and urgency, and then identify the background and meaning of this theme. Then mean sure Solid Ink Density、dot gain value and gray balance by experimenting. Then from contrasting Empirical data and standard to appraise these control methods, to find their advantage and disadvantage. At length , the author make use of these control methods to printing process in normal times by the method of factoring Printing beta combine with each chapter. This article introduces G7 process especially, and combines this control method with traditional printing beta to test the accuracy this control method. All of all, this article advance improving method by studying these control method, and it make it shortcut to improve the printing quality in our country.
