JEITA灰阶测试卡（灰度γ=2.2）
产品介绍：
JEITA灰阶测试卡（灰度γ=2.2）主要测试饱和度，灰阶代表了由最暗到最亮之间不同亮度的层次级别。这中间层级越多，所能够呈现的画面效果也就越细腻。
1、灰度的透明/反射率和密度请参考下表。
| 步骤 | 1(白) | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 背景 |
| 反射率(%) | 89.9 | 77.3 | 63.0 | 48.6 | 37.8 | 27.9 | 19.8 | 13.0 | 8.1 | 4.5 | 2.0 | 18.0 |
| 密度 | 0.05 | 0.11 | 0.20 | 0.31 | 0.42 | 0.55 | 0.70 | 0.89 | 1.09 | 1.35 | 1.70 | 0.74 |
2、步骤1的反射率值89.9％将波动到按照基材80％左右。
1.Please refer to transparent / reflection ratio and density of grayscale in following table.
| Step Number |
1 (white) |
2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | Background |
| Reflection Ratio(%) | 89.9 | 77.3 | 63.0 | 48.6 | 37.8 | 27.9 | 19.8 | 13.0 | 8.1 | 4.5 | 2.0 | 18.0 |
| Density | 0.05 | 0.11 | 0.20 | 0.31 | 0.42 | 0.55 | 0.70 | 0.89 | 1.09 | 1.35 | 1.70 | 0.74 |
2.The value of reflection ratio of step 1 89.9% will be fluctuated to approx 80% in accordance with the base material.
