6.5 Consider a CMY printer characterized through the 3-D LUT given in Table 6.19.
(a) Use trilinear interpolation to find the L*a*b* values corresponding to the following CMY patches:
![Patch 1: CMY1 = [20 20 20] Patch 2: CMY2 = [40](https://dsd5zvtm8ll6.cloudfront.net/images/question_images/1725/4/3/0/66766d7fb8b294681725430482993.jpg)
(b) Is this printer gray balanced?
![40 40] Patch 3: CMY3 = [60 60 60] Patch 4: CMY4](https://dsd5zvtm8ll6.cloudfront.net/images/question_images/1725/4/3/0/69766d7fba9770af1725430513288.jpg)

Patch 1: CMY1 = [20 20 20] Patch 2: CMY2 = [40 40 40] Patch 3: CMY3 = [60 60 60] Patch 4: CMY4 = [80 80 80]
