| 中文摘要: |
| 分析了基于G7工艺印刷质量控制的关键参数，即亮调范围HR中性灰密度值的控制以及中性灰密度曲线NPDC。在保证设备性能稳定且印刷材料符合标准的情况下，使用G7工艺进行了印刷测试实验，然后测量相关数据并绘制了NPDC曲线，进行灰平衡校正。最后进行了验证特性化测试，应用校正补偿曲线重新出版印刷，测量灰平衡数据，再次绘制了NPDC曲线，发现结果基本符合标准曲线的趋势。 |
| 英文摘要: |
| The key parameters in printing control method based on G7 process were analyzed, which were HR and NPDC curves. In conditions of devices performance stable and standard materials, a printing test was carried out in terms of G7 process, and then the data were measured to draw NPDC curve. Gray balance calibration was carried out. At the last, the accuracy of the compensation values was tested and verified. NPDC curve was plotted again. It was founded that the trend of the NPDC curve is in accordance with standard curve. |
