The two files, colour reference and measurement result, can now be compared. To do this, they must be dragged into the program window back in IMProve. It becomes visible that the colour reference contains the information of the three colours, but it returns the status NoSpace, whereas the colour measurement result contains no colour information of the primary colour, on the other hand the colour space returns a remission. These data are now directly related to each other, they finally belong together and are linked by means of the Link function in the toolbar. Once this link has been created, it is also possible to view the measurement result.

The linearity within the curves may not be perfect, as some tone values of the measurement result jump a little. The colour space can be further optimized with the Correction and Smoothing tools to obtain a smoother tone curve. Again, this file can be saved as a text file.
