I-8-1 Overall
I-8 ISO/IEC 29158 Symbol Quality
Output
Symbol Quality Parameters for direct part marking specified by ISO/IEC 29158
Supported Symbologies:
• DataMatrix ECC200
Minimum Resolution: 6.0 Pixels Per Element
I-8-1 Overall
Definition: The overall grade is the minimum grade of all evaluated parameters,
noting minimum reflectance is not evaluated.
When enabled, the overall grade is attached to the symbol output data
as a value.
Serial Cmd: <K727, overall, cell contrast, cell modulation, fixed pattern damage,
axial non-uniformity, grid non-uniformity, unused ECC>
Default: Disabled
Options: 0 = Disabled 1 = Enabled
I-8-2 Cell Contrast
Definition: Cell Contrast is calculated in accordance with the ISO 29158 specifica-
tion.
When enabled, the Cell Contrast is attached to the symbol output data
as a value.
Serial Cmd: <K727, overall, cell contrast, cell modulation, fixed pattern damage,
axial non-uniformity, grid non-uniformity, unused ECC>
Default: Disabled
Options: 0 = Disabled 1 = Enabled
I-8-3 Cell Modulation
Definition: Cell Modulation is calculated in accordance with the ISO 29158 specifi-
cation. Note the difference in the calculation for Cell Modulation versus
Modulation in ISO 15415 eliminated the need for the parameter Reflec-
tance Margin which was added to ISO 15415.
When enabled, the Cell Modulation is attached to the symbol output
data as a value.
Serial Cmd: <K727, overall, cell contrast, cell modulation, fixed pattern damage,
axial non-uniformity, grid non-uniformity, unused ECC>
Default: Disabled
Options: 0 = Disabled 1 = Enabled
I-8-4 Fixed Pattern Damage
Definition: Fixed Pattern Damage is calculated in accordance with the ISO 29158
specification.
When enabled, the Fixed Pattern Damage is attached to the symbol
output data as a value.
Serial Cmd: <K727, overall, cell contrast, cell modulation, fixed pattern damage,
axial non-uniformity, grid non-uniformity, unused ECC>
Default: Disabled
Options: 0 = Disabled 1 = Enabled
