The narrowest element in a barcode is known as a module.
•"Module width", "Module height":
You can enter a module width in these boxes or modify the set one. You can define the module height yourself or use the one suggested. You can set "Module Width" and "Module Height" in points or millimeters.
Barcodes are specified in 10 sizes (SC0 thru SC9). The SC sizes determine the module width, in other words, the width of the narrowest bar.
The following table shows you the dimensions for EAN-13:

•"Optimized for...":
Optimizes the module with regard to the target resolution.
•"Bar Distance":
Some barcodes permit the bar distance to be modified manually.
•"Bar Width Adjustment":
You can set bar width adjustment in points or millimeters.
You can offset the dot gain resulting, for example, from the absorbency of the paper used with bar width adjustment. Dot gain would make the bars wider than intended, a fact which would noticeably restrict the read capability of the barcode.
