When I measure a particular piece of paper with just spotread, I get this:

> Result is XYZ: 88.509296 91.511759 75.273499, D50 Lab: 96.620372 0.501330

But when I add -i D50_0.0.sp, I get this:

> Result is XYZ: 87.826439 91.487282 72.041893, D50 Lab: 96.610330 -0.708287 
> 2.983602

Why the large discrepancy? I thought spotread used D50 by default? Is there 
more than one D50...?

Cheers,
