Description
horizontalMarkMisplacement
Metric
SEMI T10 (DataMatrix)
Horizontal Mark
Misplacement is the
average horizontal
misplacement of Data
Matrix marks from
their optimal Data
Matrix Cell Center
Points.
verticalMarkMisplacement
Metric
SEMI T10 (DataMatrix)
Vertical Mark
Misplacement is the
average vertical
misplacement of Data
Matrix marks from
their optimal Data
Matrix Cell Center
Points.
cellDefects
Metric
SEMI T10 (DataMatrix)
Cell Defects is the
ratio of incorrect
pixels to total pixels in
the grid.
finderPatternDefects
Metric
SEMI T10 (DataMatrix)
Finder Pattern Defects
is the ratio of incorrect

Overall grade
calculated from the
individual metrics.
edgeDetermination
Metric ISO/IEC 15416
Edge Determination is
the number of edges
detected in the Scan
Reflectance Profile. If
the number of
detected edges is
greater than or equal
to the expected
number of edges, the
grade is 4. Otherwise,
the grade is 0.
defects
Metric ISO/IEC 15416
Defects are
irregularities in
elements (bars and
spaces) and quiet
zones. The parameter
is used to measure
the ‘noise’ that results
from unwanted dips
and spikes in the
Scan Reflectance
Profile. The smaller
the defect, the better
the grade.
