15 2D code object
Specify any of the following parameters:
• “Laser power correction [%]”:
To correct the laser power, enter a value in the text box.
Marking is not possible if the laser power correction value is 0.
• “Scan speed correction [%]”:
To correct the scan speed, enter a value in the text box.
• “Pulse cycle correction [%]” (LP-RF, LP-RV):
To correct the pulse cycle, enter a value in the text box.
If the corrected value exceeds the allowable limit, the marking is performed with the
maximum or minimum parameter value. The correction ratio is calculated based on the value
set as 100% in “Laser settings”.
For bar code or 2D code objects, you can fine-tune the time until the laser starts radiating at
the start or end point in “Laser settings” under “Customize starting/ending point by object”.
• “Number of overwritings”:
Specify how many times the selected code element is marked with one single trigger.
For example, if you want to mark selected code elements, e.g. dark modules and light
modules, with individual values, specify “Number of overwritings” for each code element.
To set how many times the whole 2D code is marked, specify a value for “Number of
overwritings” in the “Object group” settings.

15.15 Specify quiet zone filling parameters for QR Code and Data Matrix
You can set parameters for the quiet zone, for example set a filling pattern, specify details for
the filling lines and correct laser parameters.
The parameters under “Quiet zone fill” become available if “Marking ON/OFF” > “ON” is set
for “Light module”.
To determine the optimal filling pattern for the quiet zone, check the marking time and the
marking quality of the code's corners.
• To edit the parameters of a 2D code object, select the object in the object list or in the
marking image editor.
