This service generates barcode labels The labels are arranged on an A4 or Letter size page or a label printer for printing from a web browser. If you are not a subscriber the service will generate defaced images.
To use our services as a subscriber you need a password from dLSoft, which is sent to you via e-mail. The password enables you to use any of our online services during the period of your subscription. Before subscribing you should check that you can access the trial service, which generates defaced barcode labels.
Please ensure that you can use the service and print labels on your printer before subscribing.
Labels Online and Barcodes Online are both provided on a single subscription for 1 year or until a specified number of Barcodes Online have been used. During the subscription period the use of Labels Online is unlimited. (So if you do not need to use Barcodes Online you should obtain a Level 1 subscription.)
For use on retail products you cannot just invent the
numbers. You must register with your national article
numbering body (GS1UK in the UK, the GS1US in the USA) to
obtain a company code number and a range of product code
numbers. Together these numbers form Global Trade Item
Numbers (GTIN) which form the data for the barcodes. Without
these numbers your barcodes will not be recognised when you
products are scanned at a retail outlet. Furthermore you
will probably need to use either EAN (in Europe), JAN (in
Japan) or UPC (in the USA) barcode types for retail
products, and, if appropriate, you may need to use Code 128
or EAN 128 barcodes on boxes containing multiple items.

If you are creating barcodes for use in a retail environment (eg. GS1/EAN-13 or UPC-A) then you should also consider the size of the barcode. The recommended barcode sizes page provide the sizes you would use for creating the barcode at 100% of the nominal size recommended by GS1. GS1 typically permits the size the range between 80 - 200% of this nominal size, and that means when both the height and the width of the image vary by the same proportion. If you need to truncate the barcode to fit on small packaging you are advised to check that the resellers of your products find this acceptable (in our experience many will, but some won't!)
The following extract from the GS1 specifications explains the reason for this:
“Truncation of a barcode symbol is the reduction of the barcode symbol height relative to the width. Truncation is not recommended because it destroys the ability of a symbol to be scanned omni-directionally at the point of sale. A truncated symbol can only be scanned when the trade item is oriented in particular directions across the scanning beam. Truncation therefore reduces checkout efficiency. The more the height is reduce the more critical becomes the alignment of the symbol across the scanning beam. Truncation should be avoided unless absolutely necessary, for example, when printing on a highly curved surface, and then the maximum height should be printed.”
