Java Barcode GS1 128 / EAN 128 Generator Introduction
Top
Java Barcode is a Java barcode generator which generates high quality 1D (linear) and 2D (matrix) barcodes in Java, Jasper Reports, iReport, and Eclipse BIRT projects.
GS1 128 / EAN 128 Introduction
GS1-128 is an application standard of the GS1 implementation using the Code 128 barcode specification. The former correct name was UCC/EAN-128. Other no longer used names have included UCC-128 and EAN-128. GS1-128 uses a series of Application Identifiers to include additional data such as best before dates, batch numbers, quantities, weights and many other attributes needed by the user.
Java GS1 128 / EAN 128 Generator - Valid Data Scope
- All 128 characters of ASCII
- Values 128-255 in accordance with ISO 8859-1. There are referred to as extended ASCII.
Creating GS1-128 (UCC/EAN-128) Compliant BarCodes in Java
Top
OnBarcode Java Barcode Generator allows easily to add application identifiers in GS1 128 / EAN 128, by add parentheses to AIs.
For example, to encode AI (00), with data 350123451234567894, with second AI (21), with data 01234567, you need pass string "(00)350123451234567894(21)01234567" to barcode data property
For example, to encode AI (00), with data 350123451234567894, with second AI (21), with data 01234567, you need pass string "(00)350123451234567894(21)01234567" to barcode data property
EAN128 barcode = new EAN128(); barcode.setData("(00)350123451234567894(21)01234567"); barcode.drawBarcode("C://demo//gs1-128-demo.png");

How to Customize, Print GS1-128 Text Label in Java?
Top
You can easily create, customize, print GS1-128 barcode text label font style using Java Barcode Generator library.
- Set property
TextMarginto control the space between GS1-128 bar modules and text label. - Disable property
AutoResizeBarcodeTextto false to customize text label font size manually. - Set property
TextFontwith the specified text font style, size inFontobject
Note: The GS1 system recommends to use font "OCR" for GS1-128 text label.
EAN128 barcode = new EAN128(); barcode.setData("(00)395123451234567895"); barcode.setTextMargin(5); barcode.setAutoResizeBarcodeText(false); barcode.setTextFont(new Font("ocr-b", Font.PLAIN, 14)); barcode.drawBarcode("C://demo//gs1-128-text-label.png");
How to Create & Encode GS1-128/EAN-128 image in HTML or JSP pages?
Top- Under demo package, copy barcode folder and its contents to your tomcat.
- Start tomcat, navigate to http://YourDomain:Port/barcode/barcode?DATA=(00)350123451234567894&TYPE=EAN128
- To create bar code images in html or jsp pages, you can insert a image tag (img) into your page
- For example, <img src="http://YourDomain:Port/barcode/barcode?DATA=(00)350123451234567894&TYPE=EAN128"/>

Common Asked Questions
What is the content of GS1-128?
GS1-128 barcode contains up to 48 characters of GS1 data message.
It may encode logistical information, such as batch/lot numbers, product serial number,
produce date, expiration date, weights, price.
OnBarcode Java GS1-128 Barcode Generator library supports GS1 data message encoding in GS1 supported barcode formats,
including GS1-128, GS1 QR Code, Data Matrix, ITF-14, GS1 DataBar, EAN/UPC barcodes.
What is the function code for GS1-128?
The GS1-128 barcode supports one function code Function Code 1 (FNC1). The FNC1 character should be encoded after GS1-128 start character.
Using Java Barcode Generator api, the barcode library will automatically encode the FNC1 character in the right position
in the Code 128 barcode in Java web and desktop application.
What is the minimum & maximum size for GS1-128 barcode?
- The minimum width for the X-dimension (the width of the narrowest bar or space) is 0.495 mm.
- The maximum width for the X-dimension is 1.016 mm
setX() in Java project.
What is the difference between GS1-128 and GTIN 14?
Both barcode formats encode GS1 business data messages.
The GS1-128 barcode can encode multiple GS1 application identities (ID) and their data information, such as serial number, price, production dates.
The GTIN 14 (also known as ITF-14, based on Interleaved 2 of 5) can only encode the 14 digits Global Trade Item Number (GTIN).
OnBarcode Java Barcode Generation library allows Java programmers to easily make GS1-128 and ITF-14 barcode in Java applications.
OnBarcode Java Barcode Generation library allows Java programmers to easily make GS1-128 and ITF-14 barcode in Java applications.
What is the difference between Code 128 and GS1-128?
GS1-128 (also known as EAN-128, UCC-128) is an application of Code 128 required by GS1 System. GS1-128 encodes a subset of Code 128 encoding characters.
Using OnBarcode Java Barcode Generator library, you can easily create and customize both Code 128 and GS1-128 barcode images in
Java web and desktop apps.
