How Can I Obtain a Fixed QR Code Size During Export?
By default, the bar code size depends on the module width (dot size) and the size of the selected matrix (symbol version). The matrix size is automatically chosen depending on the amount of data for each bar code.
- First identify the record with the maximum data length (and data complexity).
- Copy the data into the Data text box in the General tab and adjust the desired size (use Optimize and your output DPI).
Then you have two options:
Limit the Matrix Size
Use a fixed size for the matrix. The capacity is then limited. The matrix size (version) must be large enough for the maximum occurring data length.
- In the QR Code tab set the matrix size (symbol version) to the smallest version without error.
The exported bar codes will have the same size. The matrix version and dot size is constant.
Lock the Total Size
Lock the total size. Don’t use a fixed matrix size (version), the capacity is not limited.
- In the data list there is a check box Lock bar code size at the bottom of the list. Once checked, the export will use the size from the General tab for all bar codes.
A constant symbol size is maintained during export, but the matrix version and dot size may vary due to the amount of encoded data. Since the dot size is not constant it may become too small if the overall size is not large enough.
With both options you have to test scan/read the barcode with the maximum data amount. If it is difficult to read, increase the module width in the General tab. If the bar code becomes too large, you can also reduce the error correction level in the QR Code tab, then the matrix size will be a bit smaller.
