<h3>Usage Details and Discussion</h3>
mppcheck provides a way of checking how well an <a
href="File_Formats.html#MPP">MPP</a> profile conforms to the test
sample data that was used to create it. This is the same sort of check
done within the profile making tool (<a href="mppprof.html">mppprof</a>),
but having a separate tool provides some flexibility. <br>
<br>
The <b>-v</b> flag prints out extra information during the checking.<br>
<br>
The <b>-c</b> option causes the differences between the test values
and
the profile prediction of the color for each device value to be
displayed
in CIE94 delta E, rather than plain L*a*b* delta E. CIE94 delta E has a
closer
correspondence with perceived color differences than the default CIE76
delta E values.<br>
<br>
The <b>-k</b> option causes the differences between the test values
and
the profile prediction of the color for each device value to be
displayed
in CIEDE2000 delta E, rather than plain L*a*b* delta E. CIEDE2000 delta
E has a
closer
correspondence with perceived color differences than either CIE76 or
CIE94 delta E values.<br>
<br>
The <b>-s</b> flag causes the spectral model (if present) to be
checked against the test data spectral values (if present). Errors are
given as a percentage error for each reflectance band, as well as a
delta E of the resulting CIE color computed from the spectral values.<br>
<br>
The <b>-y</b> flag when used in combination with the <b>-v</b> flag,
causes each test value and its error to be printed. <br>
