Maxwell Render | Official public forum

when rendering product labels for one of my clients, they will sometimes provide me with scanned spectral data from a Gretag Color Eye XTH. I have no clue what the hell i'm looking at on these sheets honestly. Is there a way this data can be translated and used in maxwell render to create complex ior sheets, or anything like that? below is showing what I will get with the color swatches:

There are XYZ values measured under D50 at the top of the table.
So, you can extract a useful input by doing the following:

1) Convert XYZ(D50) to XYZ(D65) using the adaptation calculator below. (Because, our internal white point is ~6500K)

You will find the following values for your example:
X = 30,342314
Y = 32,222998
Z = 37,115116

2) Convert XYZ(D65) to xyz using the following equations.
x = ( X / ( X + Y+ Z ) )
y = ( Y / ( X + Y+ Z ) )
z = ( Z / ( X + Y+ Z ) )

So, now the values below are compatible with our color picker.
x = 0,33354
y = 0,35421
z = 0,40799

thanks for the feeback, Tom. I've tried the xyz data, but it always came out to be off hue...now it makes sense that'll be a big help when trying to get accurate colors created
