摘 要：在印刷复制过程中，油墨叠印后得到的中性灰色往往容易产生色偏。然而人眼对中性灰色十分敏感，稍有偏差就会察觉，所以中性灰平衡常常被作为控制色彩稳定性的重要手段。
 G7工艺就是以控制灰平衡为主的一种新的印刷工艺方法，其目的就是要在CTP 的协助下，最终实现商业胶印的同貌效果。G7工艺的出现，为印刷的复制工艺又提升了一个新的台阶。为配合G7工艺更好地进行彩色复制，G7测试版便成为其最重要的检测工具。G7测试版以其多元化的设计，全方面检测印刷复制过程中所会出现的问题。
 本课题通过对G7印刷测试版的各部分内容全面解析，并与传统印刷测试版进行功能比较，分析各自优势和各自的控制要点，最后将结合各自优势，把现有的G7印刷测试版进行进一步改进，为今后G7工艺的研究奠定理论和实践基础，最终更加提高印刷复制水平。

Abstract: During the printing reproduction, accurate color reproduction can not be reproduced and neutral gray overprinted always has color slanting. However, the human eye is very sensitive to the neutral gray and a little color slanting can be aware. Therefore, neutral gray balance is often as an important means of controlling color stability.
G7 process is the main method of a new printing technology to control gray balance. Its purpose is to help in the CTP and ultimately to effect of the same appearance in the commercial offset. With G7 process occurs, the print reproduction process has raised a new level. In line with the G7 process to better color reproduction, G7 test form will become the most important detection tool. With G7 test form's diversified design; it tests all aspects of reproduction problems in the process of printing that would arise.
This article will comprehensively analyze every part of G7 test form and compare with the traditional printing test form. Then, analyze their strengths and their respective control points. Finally combine their respective strengths to improve the current test form of G7 printing. It will lay the theoretical and practical basis for the future G7 technology and improve the final print copy level.

Key words: G7 process; G7 standard test form; traditional printing test form; gray balance
