Usage Details and Discussion

+This is an analogous tool to colprof, +but applying to +MPP profiles, rather than ICC profiles. This tool creates an +MPP profile given the .ti3 test +chart information. The model based device profile is an Argyll specific +format, used to hold the parameters to a general model based device +characterization. +This is a less precise and general format than and ICC profile, but is +a compact way of representing a devices response when it has a large +number +of color channels, or when very few measured data points are available +for its construction.
+
+The -v flag causes extra information to be printed as the +profile is being created, including the delta E statistics for the test +data fit against the profile.
+
+The -q parameter sets the level of effort and hence quality in +the resulting profile. Different quality profile use different numbers +of +model parameters.
+    s      simple - use a close +variation +of the Neugenbauer model, with a single parameter, per device +linearisation curve.
+    l       low quality +profiles +have more detail terms to account for device linearisation.
+    m     medium quality profiles, add +color channel cross mixing terms, as well as using more detail +parameters.
+    h      high quality profiles, +use more detail terms and more profile refinement iterations.
+
+The -l flag overrides any default ink limit (Total Area +Coverage) recorded in the .ti3 file.
+
+The -s flag enables the creation of spectral model values, as +well as the tri-stimulus model.
+
+The -m flag is currently not implemented.
+
+The -y flag causes each test value and its error to be printed.
+
+The -L flag causes the CGATS output file to contain D50 L*a*b* +parameters rather than XYZ.
+
+The inoutfile parameters should be the base name of the .ti3 +file, and mppprof will output an mpp that has the same basename and the +.mpp extension.
