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. Different quality profile use different numbers of model parameters.<br> <b>s </b>simple - use a close variation of the Neugenbauer model, with a single parameter, per device linearisation curve.<br> <b>l</b> low quality profiles have more detail terms to account for device linearisation.<br> <b>m</b> medium quality profiles, add color channel cross mixing terms, as well as using more detail parameters.<br> <b>h</b> high quality profiles, use more detail terms and more profile refinement iterations.<br> <br> The <b>-l</b> flag overrides any default ink limit (Total Area Coverage) recorded in the .ti3 file.<br> <br> The <b>-s</b> flag enables the creation of spectral model values, as well as the tri-stimulus model.<br> <br> The <b>-m</b> flag is currently not implemented.<br> <br> The <b>-y</b> flag causes each test value and its error to be printed.<br> <br> The <b>-L</b> flag causes the CGATS output file to contain D50 L*a*b* parameters rather than XYZ.<br> <br> The <i>inoutfile</i> 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.<br> <br> <br> <br> <br> <br> <br> </body> </html>
