| 摘要: |
| 阐述了G7工艺的目的、控制的目标和实施步骤，详细阐述了3个控制变量HR（亮调范围）、SC（暗调反差）和HC（亮调反差）及其控制范围，介绍了NPDC（中性灰印刷密度）曲线的作用及校正方法，最后介绍了ICC（国际色彩联盟）文件的制作，并以此为基础对比了G7工艺与传统密度法工艺的色域。结果表明，G7工艺的色域要优于传统工艺的色域。 |

| Abstract: |
| The purpose, control targets, and implementation procedures of G7 technology were introduced. Three control variables (HR, SC, and HC) and their control ranges were elaborated. The NPDC curve and its correction method were also presented. The ICC file making method was introduced; the gamut of G7 technology and conventional density technology were compared based on ICC file. The results showed that the gamut of G7 technology was superior to that of conventional technology. |
