JasperReport Barcode UPC-A Generator Introduction

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.

In this page, we will explain how to create, print UPC-A barcodes within JasperReport reports using Jaspersoft Studio (official Eclipse-based report designer) or iReport Designer (legacy Swing-based report designer). Here's a list of key topics covered in this page:

Quick steps to insert and generate UPC-A as a Barcode image in a JRXML (XML source template file) using Jaspersoft Studio or iReport Designer, including data requirements and basic configuration.
Guidance on customizing UPC-A barcodes in JasperReport reports, including settings for quiet zone indicators, digit spacing, digit position, and font size.
Step-by-step instructions for adjusting UPC-A's first and last digit properties (spacing, vertical offset, font size ratio) via the Report Item Property panel.
Explanation of UPC-A check digit calculation (modulo 10) and how the JasperReport Library (core Java reporting engine) handles check digit validation and generation.

Please follow the steps to create a UPC-A barcode in iReport. View details here: how to generate and print barcodes in iReport reprts.

One more method to print UPC-A: stream UPC-A barcodes in iReport using Java Barcode Generator buildin Servlet web application.

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
Right click on the image and edit its "Properties", and set property "Expression Class" to "net.sf.jasperreports.engine.JRRenderable";
To input UPC-A barcode data manually, set property "Image Expression" to "new com.onbarcode.barcode.jasper.JasperRenderer(
com.onbarcode.barcode.jasper.BarcodeGenerator.draw(19, "12345678901", "", "X=2&Y=60"))"
To print UPC-A with data from database, please set property "Image Expression" to "new com.onbarcode.barcode.jasper.JasperRenderer(
com.onbarcode.barcode.jasper.BarcodeGenerator.draw(19, $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 UPC-A property table below

Print and Customize UPC-A Barcodes in JasperReport Reports

You can fully customize UPC-A barcodes in JasperReport reports to meet your report design and scanning requirements. These settings include quiet zone indicators, digit spacing, digit position, and font size adjustments.

The key customization properties for UPC-A barcodes in JasperReport reports are:

ShowQuietZoneIndicator: Controls whether to display or hide the UPC barcode quiet zone indicator. The default value is true.
UPCEANLeadDigitSpace: Defines the space between the first digit (Human Readable Interpretation, HRI) and the start character bar. The default value is 0.
UPCEANTrailDigitSpace: Defines the space between the stop character bar and the quiet zone indicator. The default value is 0.
UPCEANLeadTrailDigitSizeRatio: Controls the font size of the first and last digits relative to the rest of the digits in the HRI. The default value is 1.0f (equal size).

Customize UPC-A Quiet Zone Indicator

The quiet zone indicator is a small mark at the end of the UPC-A barcode, indicating the end of the quiet zone (empty space around the barcode). You can show or hide this indicator via the Report Item Property panel, following these steps:

Select the UPC-A Barcode Component and open the Report Item Property panel.
Locate the "ShowQuietZoneIndicator" property.
Set it to "false" to hide the quiet zone indicator; leave it as "true" (default) to display it.
Save the JRXML template to apply the setting.

Note: Do not reduce the RightMargin below the minimum 9X requirement when hiding the quiet zone indicator. Insufficient quiet zone will cause scanning errors.

Customize UPC-A First/Last Digit Spacing, Position, and Font Size

You can adjust the spacing between the first/last digits and the barcode bars, the vertical position of the first/last digits, and their font size relative to other digits.

UPCEANLeadDigitSpace: Adjusts the space between the first digit and the start bar.
UPCEANTrailDigitSpace: Adjusts the space between the stop bar and the quiet zone indicator.
UPCEANLeadDigitYShift: Adjusts the vertical offset (up/down) of the first digit in the HRI.
UPCEANTrailDigitYShift: Adjusts the vertical offset (up/down) of the last digit in the HRI.
UPCEANLeadTrailDigitSizeRatio: Adjusts the font size of the first and last digits relative to the rest (e.g., 0.6f means 60% of the default font size).

Note: Avoid setting the UPCEANLeadTrailDigitSizeRatio too small (e.g., below 0.5f), as this may make the first/last digits unreadable. Also, ensure the vertical shift does not move the digits outside the report's Report Band.

Calculate UPC-A Check Digit in JasperReport Reports

The UPC-A check digit is a mandatory component calculated using a modulo 10 (mod 10) algorithm. It ensures data integrity by validating the UPC-A number. The JasperReport Barcode Generator Library automatically calculates and adds the check digit if you provide 11 digits, but understanding the calculation process helps in troubleshooting invalid data.
