QTR-Quadtone RIP

Hi,

printed QTR-51-random wedge, messured with EyeOne Pro Rev b. I've done
five meassurements and used the average tool in MeasureTool afterwards.

But when trying to create a curve, I get a "Invalid linearization
curve - not constantly increasing" error. Why?

Here are my measurements: Step	Dens	Lab	A	B
