ISO/IEC 16022 Symbol Quality Output
Symbol Quality Parameters for Data Matrix symbols specified by ISO/IEC 16022.
Symbol Contrast
Print Growth
Usage:
Lets the user know if contrast settings are less than acceptable.
Definition:
All the pixels that fall within the area of the test symbol, including its
required zone, will be sorted by their reflectance values to select the
darkest 10% and the lightest 10% of the pixels. The arithmetic mean of
the darkest and the lightest pixels is calculated and the difference of the
two means is the Symbol Contrast.
(ANSI) Symbol Contrast grading is defined this way:
A (4.0) if SC > 70%
C (2.0) if SC > 40%
F (0.0) if SC < 20%
B (3.0) if SC > 55%
D (1.0) if SC > 20%
If enabled, the symbol contrast is appended to the symbol data according
to the
ISO/IEC 16022 Symbol Quality Output Mode
setting.

Definition:
The extent to which dark or light markings appropriately fill or exceed
their module boundaries. These values are determined by counting pixels
in the clock pattern of the binary digitized image, then comparing it to a
nominal value and minimum and maximum values. The print growth
grade is defined in this way:
A (4.0) if -.050 < PG < 0.50
B (3.0) if -.070 < PG < 0.70
C (2.0) if -.085 < PG < 0.85
D (1.0) if -.10 < PG < 1.00
F (0.0) if PG < -1.00 or PG > 1.00
If enabled, the print growth is appended to the symbol data according to
the
ISO/IEC 16022 Symbol Quality Output Mode
setting.
