Cell recognition rate CRR
The rate is calculated based on the "the number of error code word to be
co
rrectable", which is determined by the size and the error correction level,
and the number of error code words that are actually corrected.
(1 - (number of error code words corrected) / (number of error code words
th
at can be corrected)) × 100
Contrast CT Contrast

Overall quality GD0
This is given the lowest weight of the various quality grades.
This grades value is most small in each qualities.
Decode GD1 A quality grade which shows whether the decode is successful or not.
Contrast GD2
A quality grade which shows the contrast.
The grade will be high when the difference of highest and lowest brightness
a
r
e large in code region.
Modulation GD3 A quality grade which shows the uniformity of cells brightness.
Fixed pattern damage GD4
A quality grade which shows the damage level
of the followings:
•Finder pattern
• Timing pattern
• Quiet zone
Axis non-uniformity GD5
A quality grade which shows the ratio of
co
de width and height.
A cell figure which is close-to-square has high grade.
Grid non-uniformity GD6
A quality grade which shows the amount of verti
cal displacement from the
ideal position.
Unused error correction GD7
A quality grade that shows the percen
t
age of error corrected items.
A grade which is less errors is high grade.
Print Scale GD8
A quality grade that shows the percen
t
age of error corrected items.
A grade which is less errors is high grade.
Print Scale X GD9
A quality grade which shows the uniformity of
black c
ell size and white cell
size.
This grade value is a Print expansion/contraction X or Print expansion/
contra
ction XY.
Print Scale Y GD10 A grade is high when the white and black cell of Y direction.
Overall quality GP0
This overall grade is a code to be read.
This is given the lowest weight of the various quality grades.
Decode GP1
A quality grade which shows whether the start pattern, stop pattern, or
sp
ecified
line were successfully decoded, or not.
RAP contrast GP2
A quality grade which shows whether the start pattern, stop pattern, or
specified line were successfully decoded, or not.
The grade will be high when the difference of highest and lowest brightness
are
large in pattern region.
RAP minimum
reflection rate
GP3
A quality grade which shows the contrast of the st
art pattern, stop pattern, or
specified line.
