This tool creates an +MPP profile given the <a href="File_Formats.html#.ti3">.ti3</a> 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.<br> +<br> +The <b>-v</b> 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.<br> +<br> +The <b>-q</b> parameter sets the level of effort and hence quality in +the resulting profile.
