 Cell Modulation
Like Cell Contrast, Cell Modulation is a modified version from ISO 15415. Cell Modulation is calcu-
lated in accordance with the ISO 29158 specification. Note that the difference in the calculation for
Cell Modulation versus the Modulation parameter in ISO 15415 also eliminated the need for ISO
29158 to adopt Reflectance Margin, which was added to the ISO 15415 specification.
 Fixed Pattern Damage
Fixed Pattern Damage is an evaluation of the elements in the fixed patterns of the symbol that are
used for locating and extracting the data successfully. Fixed Pattern Damage is calculated in accor-
dance with the ISO 29158 specification.
 Axial Non-Uniformity
Axial Non-Uniformity measures the relationship between the overall dimensions of the two axes of
the symbol. Axial Non-Uniformity is calculated in accordance with the ISO 29158 specification.
 Grid Non-Uniformity
Grid Non-Uniformity measures the difference of the decoding grid in relation to the ideal grid
formed from the four corners of the symbol. Grid Non-Uniformity is calculated in accordance with the
ISO 29158 specification.
 Unused Error Correction
Unused Error Correction measures the remaining error correction available after correcting the
errors within the decoded symbol and is calculated in accordance with the ISO 29158 specification.
