To open the Fixups window, click on the Fixups option in the menu or press ⌘+5 / Cmd+5 (on Mac OS X) or Ctrl+5 (on Windows).

1. Enter “EAN” in the search box to restrict the list of Fixups shown to those containing the term “EAN”.
2. Select the Fixup named “Place EAN 13 barcode with specified value”
3. Click “Fix” to place the EAN 13 barcode.

Important: There must already be an open document.

"Beginning with version 9, you will find this Fixup in the Library "Shapes, Variables, JavaScript, Place content".

A dialog window will appear where you can enter the value for the EAN 13 barcode that will be placed in the file. If no entry is given, the default value will be used.

Important: The value entered must consist of 12 or 13 digits. If 12 digits are entered, pdfToolbox will automatically calculate the required check digit. If 13 digits are entered, the 13th must be a valid check digit, otherwise the attempt to place the barcode will return an error. When testing the system, provide a 12-digit value.

Important: If in doubt, please double-check that the original document will not be overwritten. Choose a new file name or save the document in another directory.

After processing is complete, pdfToolbox will display a report on the results. In this example, 346 barcodes have been placed (one code on each of the 346 pages).

Clearly, the positioning of the EAN 13 code as shown here will not be suitable in most cases. In practice, you will usually need to make adjustments to the position of the barcode on the page as well as its size. Consider also whether a barcode is required on every page or only on certain pages.

These adjustments are easy to make, as the following steps will show.

Duplicating a Fixup creates a virtually identical copy (item 2) of the original Fixup - with the only difference being that “(Copy 1)” has been added to the name (item 1).

In order to adapt the Fixup named “Place EAN 13 barcode with specified value” to your own requirements, it is usually advisable to create a copy of the existing Fixup and make the required changes to this copy.

This graphic shows the original settings to which we will make a number of changes in order to correctly position and color the EAN 13 code.

For the following steps, we will assume that a variant is required which places the EAN 13 code 

• with a font picked from the computer
• at the bottom left of the page
• colored in a specific dark blue which we will name “EAN13-Spotcolor”
• not on a layer

All other settings, such as the size of the EAN 13 code or the font type for the code’s digits, will be preserved.

1. 'Method' allows to add:
   • Font families
   • Web fonts
   • Fonts from library
2. Upon selecting 'Fonts from library' method, fonts can be imported from the system
3. The barcode’s position will now be relative to the bottom-left corner of the page
4. Options to create a layer and assign the barcode to this layer have now been disabled
5. The CMYK color values have been adjusted, resulting in a dark blue color instead of black
6. “Create as spot color” has been enabled, and the name of the spot color has been given as “EAN13-Spotcolor”

Click “Fix” to call the updated Fixup for the current open document.

The EAN 13 code is now located at the bottom left corner of the page.
