Hi,

 

Has anyone create an Australia Post eParcel barcode and able to tell me the correct settings for the Code128 barcode? It should be 300dpi have a width of 4/300 and a height of 0.63. I am not quite sure how to set the dpi and width.

 

Thanks.

  Hello George,

   

  The barcode width depends on the following traits:

   

  1. How much information is being encoded.

   

  2. What type of symbology is in use.

   

  3. The printer's dpi used at that moment, which affects the X dimension and density values.

   

  When talking about barcodes, the X dimension refers to the width of the narrowest unit in a bar code. Wider elements in the bar code (typically, bars or spaces in the bar code) are then measured as multiples of the X dimension. Therefore, the X dimension correlates directly with the overall width of the bar code.

   

  The available values for X dimension rely on the resolution and type of printer that is being used. The options available for a 300 dpi (dots per inch) printer will differ from those of a 2400 dpi printer, due to the size of dots that are printed. The higher the dpi value is, the smaller the narrowest unit in a barcode will be, and you’ll be able to change the total width of the barcode in smaller “steps”.

   

  The X dimension is used to determine the density of a bar code, which defines how many characters can be encoded per inch of bar code. When you decrease a bar code's X dimension, you increase its density; furthermore, if you increase the X dimension, you effectively decrease its density.

   

  One factor controlling the density of a barcode is its symbology. Different symbologies require different numbers of bars and spaces to represent the same information.

   

  If you are not able to set the desired barcode width it's probably due to the information contained and to the printer's dpi not allowing you to set the appropriate X dimension.

   

  Regards.
