JasperReport Barcode EAN 13 Generator Introduction

Top

iReport Barcode is a NETBeans iReport Custom Extended Report Item which helps you easily generate and print high quality 1D (linear) and 2D (matrix) barcodes in your iReport reports.

Barcode EAN-13 Introduction

EAN-13 barcode (originally European Article Number) is a barcoding standard which is a superset of the original 12-digit Universal Product Code (UPC) system developed in the United States. The EAN-13 barcode is defined by the standards organisation GS1. The numbers encoded in EAN-13 bar codes are product identification numbers which are called Japanese Article Number (JAN) in Japan. All the numbers encoded in UPC and EAN barcodes are known as Global Trade Item Numbers (GTIN), and they can be encoded in other GS1 barcodes.

Create a new report, and add barcode.jar to report classpath from the downloaded trial package
Drag an image item in Palette to report
Click "Cancel" button, in "Select an image file" window
Select the image and edit its "Properties", and set property "Expression Class" to "net.sf.jasperreports.engine.JRRenderable"
To input EAN-13 barcode data manually, set property "Image Expression" to "new com.onbarcode.barcode.jasper.JasperRenderer(
com.onbarcode.barcode.jasper.BarcodeGenerator.draw(18, "123456789012", "", "X=2&Y=60"))"
To print EAN-13 with data from database, please set property "Image Expression" to "new com.onbarcode.barcode.jasper.JasperRenderer(
com.onbarcode.barcode.jasper.BarcodeGenerator.draw(18, $F{data field} + "", "", "X=2&Y=60"))";

BarcodeGenerator.draw method accepts 4 parameters:
the second is the barcode data to encode, in String,
the last is the barcode settings String. More details about barcode settings string, please check the EAN-13 property table below

EAN-13 Barcode Add-on Symbol

EAN-13 barcodes can include a 2-digit or 5-digit add-on symbol, which is positioned after the right Margin (External spacing around an element) (quiet zone) of the main EAN-13 symbol. This add-on provides additional data (e.g., weight, price) and is fully configurable in Jaspersoft Studio or iReport Designer via the Report Item Property pane.

Select the EAN-13 Barcode Component and open the Report Item Property panel.
Set the "Barcode Type" to match the add-on length:

Select "EAN13_2" for a 2-digit add-on.

Select "EAN13_5" for a 5-digit add-on.
Enter the main EAN-13 data (12 or 13 digits) in the "Data" field (static text or dynamic Expression).
Locate the "SupData" (supplementary data) property in the Report Item Property panel and enter the add-on data (2 or 5 digits, matching the selected barcode type).
Save the JRXML template to apply the settings.

EAN-13 Barcode Text (Human Readable Interpretation, HRI)

The GS1 System recommends using the OCR-B font for the Human Readable Interpretation (HRI). The text displayed below the EAN-13 barcode. You can customize the HRI's font and the spacing between the barcode bars and the text via the Report Item Property panel.

Select the EAN-13 Barcode Component and open the Report Item Property panel.
Locate the "TextFont" property and select the OCR-B font (or your preferred font). Configure the font size (e.g., 12pt) and style (e.g., Regular) as needed.
Locate the "TextMargin" property and enter the desired spacing (e.g., 10 pixels, or 1X based on your X value). This controls the space between the barcode bars and the HRI text.
Ensure the "Data" field contains valid EAN-13 data (12 or 13 digits) and the "Barcode Type" is set to "EAN13" (or EAN13_2/EAN13_5 if using an add-on).
Save the JRXML template to apply the settings.

Customize EAN-13 Barcode in JasperReport Reports

You can further customize EAN-13 barcodes in JasperReport reports using additional properties in the Report Item Property panel. These settings allow you to adjust quiet zone indicators and spacing between digits and barcode bars, enhancing the barcode's appearance and readability.

EAN Barcode Quiet Zone Indicator

The quiet zone indicator is a small mark at the end of the EAN-13 barcode, indicating the end of the quiet zone. You can show or hide this indicator via the Report Item Property panel:

Select the EAN-13 Barcode Component and open the Report Item Property panel.
Locate the "ShowQuietZoneIndicator" property.
Set it to "true" (default) to display the quiet zone indicator, or "false" to hide it.
Save the JRXML template to apply the setting.

Note: Hiding the quiet zone indicator may affect scannability. Only do so if required by your report design, and ensure the quiet zone (LeftMargin, RightMargin) is still sufficient (minimum 10X).

EAN-13 First and Last Digit Space

You can adjust the spacing between the first digit and the start bar, and between the stop bar and the quiet zone indicator, using two properties in the Report Item Property panel:

UPCEANLeadDigitSpace: Controls the space between the first digit (HRI) and the start character bar. Default value is 0.
UPCEANTrailDigitSpace: Controls the space between the stop character bar and the quiet zone indicator. Default value is 0.

Note: Avoid excessive spacing, as it may increase the barcode's overall width and cause layout issues in your report. Test the spacing in Preview Mode before finalizing.

Verify and Calculate EAN-13 Check Digit

The EAN-13 check digit is a mandatory component calculated using a modulo 10 (mod 10) algorithm. It ensures data integrity and is automatically handled by the JasperReport Barcode Library. You do not need to calculate it manually, but understanding the process helps in troubleshooting invalid data.

How the JasperReports Library Handles Check Digits

If you enter 12 digits in the "Data" field, the JasperReport Barcode Library will automatically calculate and append the 13th check digit.
If you enter 13 digits, the library will validate the check digit to ensure it is correct. If invalid, it will throw an exception or generate an empty image with "Invalid Barcode Settings".
