曲线可视化: 基础知识选择最佳匹配

e-finder 电子查色工具

1. In the spectral curve tab you will find curves for evaluation representing 在“光谱曲线”选项卡中，你会看到用于代表评估的曲线

Four measurement angles can be seen in the graph. 15,25,45 and 75
在图表中可以看到四个测量角度：15°、25°、45° 和 75°。
Red is for the original, blue for the target and green is for the theoretical adjusted.

红色代表原始配方，蓝色代表目标色，绿色代表理论调整后的结果。
The numbers of this graphic show for which angle they are

图中的这些数字显示它们分别对应的测量角度。

The left side of the graph indicates the reflectance 图表左侧表示反射率。
Curves reaching the top of the graph indicate a color that is lighter, which is reflecting more light 曲线到达图表顶部表示颜色较浅，反射更多光线。
Curves at the bottom indicate a dark color which has less reflectance 雪线位于图表底部表示颜色较深，反射率较低。

Note: this scale will change per color displayed. Always check scaling when evaluating curve 注意：此刻度会根据不同颜色而变化，评估曲线时请务必确认刻度。

3. The horizontal line indicates where the color is within the visible light spectrum 横向的这条线表示该颜色位于可见光谱中的位置

4. Color: Wavelength Interval 颜色：波长区间

5. Example of light color 浅色示例

6. Example of dark color 深色示例

7. Example of dark blue 深蓝色示例

8. Example of dark red 深红色示例

9. When evaluating the curves be aware of the following… 在评估这些曲线时，请注意以下事项...

Some examples of bad match seen with the spectral graph

从光谱图中可以看到一些不良匹配的示例：:

In this example we still have an unacceptable quality score of 44%.

在此示例中，质量评分仍然只有 44%，属于不可接受范围。

Here the difference in lightness between the target and the match is significant in multiple areas and lines are crossing between the target and match lines signifying a possible difference in pigmentation.

目标色与匹配色在多个区域的亮度差异明显，且两者的曲线出现交叉，表明可能存在颜料体系差异。

9a. Some examples of bad match seen with the spectral graph 从光谱图中可以看到一些不良匹配的示例

This example shows a result with an original quality score of 73% and an adjusted of 91%.

此示例显示原始配方的质量评分为 73%，调整后为 91%

This graph can signify the match and the target will be a bit brighter in the 15°.

该图表表明在 15° 角度下，匹配色会比目标色稍微更亮。
The area which the lines cross and the spectral curves do not flow together can signify different pigmentations. 曲线之间出现交叉、且光谱曲线无法顺畅重合的区域，可能意味着所用颜料体系存在差异。

In this case it is advised to check the ingredients and select a match that contains the expected pigment/ effects and do a spray out.

在这种情况下，建议检查配方成分，选择包含预期颜料/效果的匹配方案，并进行喷涂样板确认。

*Refer to Steps/Photos 10a and 10b for the below information* *以下信息秦参考步骤/图片10a和10b*

In this example we can see the quality scores for result 1 and result 2 are both in the yellow but if we look at the spectral curves, we can make an informed choice of which will be a better match.

在这个示例中，我们可以看到结果 1 和结果 2 的质量评分都处于黄色区间，但如果查看光谱曲线，我们就能够更明智地判断哪一个匹配度更高。

Result on the left signifies the match is light in the 15° angle. The adjusted there looks good, the peaks are aligned, and the curves flow smoothly

左侧的结果表示在 15° 角度下，匹配色偏亮。调整后的曲线表现良好，峰值对齐，曲线流畅一致。

Result on the right has very similar quality scores to result one and the 15° angle is closer in in reflectance BUT we see the peaks are offset. This lets us know there is most likely a difference in pigmentation that cannot be fixed with correction or application.

右侧的结果虽然质量评分与结果 1 非常接近，并且在 15° 角度的反射率也更接近目标色，但我们可以看到峰值存在偏移。这表明两者的颜料体系很可能不同，而这种差异无法通过配方微调或喷涂手法来纠正。

10a.

Smooth curves with peaks aligned.

曲线平滑且峰值对齐。

This looks good! 这看起来很好！

10b.

Although the curves look closer here the peaks do not align.

虽然此处曲线看起来更接近，但峰值并未对齐。

Look at a different result! 请查看其他结果！

11a. Recap 总结

Spectral lines should

光谱曲线应当符合以下要求：:

Flow smoothly between target and match from software
目标色与匹配色之间的曲线应当平滑衔接。
Peaks align (if offset this can signify incorrect pigmentation between match and target)

峰值应对齐（如果峰值存在偏移，可能表示目标色与匹配色之间存在颜料差异）。
Have minimal crossing of spectral curves between target and match. (Many crossing lines can signify a metamerism and/or differences in pigmentation)

目标色与匹配色之间的光谱曲线应尽量减少交叉。过多的交叉可能表示存在条件等色或颜料体系差异。
If multiple results are acceptable, as it is easier to correct lightness than color, select the "lighter" curve for your spray out.

如果多个匹配结果都可接受，由于“校正亮度比校正颜色更容易”，应选择光谱曲线更“偏亮”的结果进行喷板确认。
