摘 要：在印刷復制過程中，油墨疊印后得到的中性灰色往往容易產生色偏。然而人眼對中性灰色十分敏感，稍有偏差就會察覺，所以中性灰平衡常常被作為控制色彩穩定性的重要手段。
 G7工藝就是以控制灰平衡為主的一種新的印刷工藝方法，其目的就是要在CTP 的協助下，最終實現商業膠印的同貌效果。G7工藝的出現，為印刷的復制工藝又提升了一個新的臺階。為配合G7工藝更好地進行彩色復制，G7測試版便成為其最重要的檢測工具。G7測試版以其多元化的設計，全方面檢測印刷復制過程中所會出現的問題。
 本課題通過對G7印刷測試版的各部分內容全面解析，并與傳統印刷測試版進行功能比較，分析各自優勢和各自的控制要點，最后將結合各自優勢，把現有的G7印刷測試版進行進一步改進，為今后G7工藝的研究奠定理論和實踐基礎，最終更加提高印刷復制水平。

關鍵詞：G7工藝；G7標準測試版；傳統印刷測試版；灰平衡

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
