3.2.9.6 Standard report for ISO/IEC 15416
The verification report for barcode verification according to ISO 15416 is significantly larger
than the reports of other standards because the results are output separately for each of the
10 scan lines.
With a standard report (%V), the values are output sorted according to scan lines. This means
that the fields "Scan line grade", "Edge determination grade", "Minimum reflectance grade",
"Maximum reflectance grade", … are first output for the scan line 1, followed by the same
fields for scan line 2, etc.
The "Verification type" to "Overall grade" and "Module size " to "Angle" fields are output only
once in the standard report either at the very beginning or at the very end.
In an individually formatted verification report, the fields are sorted according to scan lines as
long as they follow each other directly without a separator in the formatting instruction.
Example
• "%Qt;%Q24%Q25" generates a report in the form:
Verification type;\r10 x [scan line grade; edge determination grade\r].
• "%Qt;%Q24;%Q25" generates a report in the form:
Verification type;\r10 x [scan line grade\r]; 10 x [edge determination grade\r];
