2D Code
A quality grade which shows the contrast of the start pattern, stop pattern, or specified line.
Verify the smallest contrast between bar and space.
A quality grade which shows the brightness uniformity of the start pattern, stop pattern, or
specified line.
Verify the lowest edge contrast as against to the symbol contrast.
A quality grade which shows the brightness uniformity of the start pattern, stop pattern, or
specified line.
Verify the uniformity of brightness between bar and space.
A quality grade which shows the printed accuracy of start pattern, stop pattern, or specified
lines.
A grade is high when the width of bar or space is close to the standard values.
A quality grade which shows whether there is a sufficient Quiet zone for start pattern, stop
pattern, or specified line.
An overall quality grade for parts of the start pattern, stop pattern, or specified line.
A grade quality which shows the efficiency to read the data by scanning the record.
An evaluation of the number of code is successful decoded when repeat to scan the code.
A quality grade that shows the percentage of error corrected items.
*3
A grade which is less errors is high grade.
A quality grade which shows the printed accuracy of codes parts.
A grade is high when the width of bar or space is close to the standard values.
A quality grade which shows the uniformity of codes brightness.
Verify the uniformity of brightness between bar and space.
A quality grade which shows the uniformity of codes brightness.
Verify the lowest edge contrast as against to the symbol contrast.
Check whether there are codes to read in the measurement region.
Check if the settings, such as "Code type", "Code color", "Code length", and "Mirror setting",
are specified correctly.
Check to make sure that the specified time is not too short.
