9.7 Details summary
In the centre of the screen, a number of results are restated or shown in addition.
In the system preset, the "Reflectance margin" parameter is active according to the
grading standard. The "Contrast uniformity" is for information only. "Contrast
uniformity" is a mandatory requirement for verifying device measurement accuracy
according to ISO/IEC 15426-2.
The code analysis specification (GS1) is also activated and the result is included in the
overall evaluation if e.g. a GS1 Data Matrix code is being verified (data structure
parameter).
Details of print growth are for information only.
The first column shows the parameter name.
The second column shows the value measured in each case.
The third column indicates the relevant permissible limit values (if these exist).
The fourth column indicates the grading under the "Grade" heading (only 4 = good or
0 = fail is possible here) if the parameter has not been deactivated and a grading has
also been made. The right-hand group indicates the code's module size values.
The
module size X is the module width and module size Y is the module height.
The "module size" is the calculated as an average of module sizes X and Y.
Determination is based on the overall code width and height together with the matrix
size (amount of matrix cells in Y and X direction).
Print gain is the average print gain of the module sizes measured. Print gain is based
on the nominal module size that is calculated from the overall matrix.
