I see parentheses around the Application Identifiers AIs under some barcode symbols. Are they supposed to be there and are they encoded in the barcode? All AIs must be enclosed in parentheses in the Human Readable Interpretation, but the parentheses are not encoded in the symbol.
The optimum colour combination for good contrast in a barcode symbol is black bars with a white background. If you want to use other colours, the following may help you in choosing satisfactory ones:. As explained, black bars and white spaces are the optimal combination, but other colour combinations can be used. Consult an experienced printing company recommended by your GS1 Member Organisation for additional guidance.
When discussing symbol location, we are referring to the symbol placement on the design. When assigning symbol placement first the packaging process should be considered. You should consult the packaging engineer to make sure the symbol will not be obscured or damaged e. After determining the proper placement, the printing company should be consulted. This is because many printing processes require barcodes to be printed in a specific orientation to optimise printing processes.
An ISO-based verifier looks at the symbol in the way a scanner does but goes further by grading the symbol's quality. In addition to the minimum grade, GS1 also specifies the verifier aperture width and wavelength. Setting up different minimum specifications is similar to a university using a standardised test to determine whether applicants qualify for admission.
Several universities may utilise the same standardised test, but each sets the minimum score necessary for its applicants to be admitted. GS1 General Specifications provide a quick reference list of symbol quality specifications depending on the symbol type, the application, and the GS1 identification key the symbol is carrying. GS1 Barcodes: One pages summaries of all GS1 barcodes, including an overview of printing methods and scanning environments.
This document describes how GS1 barcodes and identification keys should be used. More information See the GS1 Identification Keys page for short introductions on the role and characteristics for each of the GS1 keys. For example: If the product requires multi-colour graphics and a barcode with dynamic data, the graphics could be pre-printed using traditional printing presses and leave a blank portion of the label for digital printing inline during production and packaging.
Headline Points Where a retailer uses a GS1 barcode, it will do so pursuant to the terms of a licence. This contains specific restrictions on how a GS1 barcode can be used. GS1 will remain the owner of any intellectual property rights in the barcode. GS1's standard terms also reserve the right for GS1 alone to take action in respect of any alleged infringements.
As set out above however, it may still be possible to pursue a claim for passing off. Where the parties to a contract intend for a GS1 barcode to be used, GS1's terms and conditions should be reviewed and specific contractual provisions should be included. For example: If a party intends that a buyer of a business or brand should not be able to use its barcodes following a sale, it is better that this is specifically addressed in the contract.
The barcodes used by the business or brand being sold are unlikely to be owned by the seller. It is likely that the barcodes will be licensed to the seller by a third party such as GS1.

Most smartphones can read DataMatrix codes, allowing them to be used for marketing, advertising, and other applications where smartphone access is desirable. The QR or Quick Response Code format was originally designed for use in the Japanese automobile industry to keep track of parts and of cars on the assembly line.
Because of its versatility, it has become widely used in a variety of industrial and consumer-oriented applications. A QR code resembles a DataMatrix code; it is square surrounded by a blank quite zone , and consists of square black and white cells. But instead of borders, it uses a set of large position and alignment squares and a smaller set of timing marks set into the body of the code.
The size and density of a QR code can vary, depending on the amount of data to be stored. A QR code can be broken up into several smaller codes, allowing them to fit into an area in which a larger code would not fit. QR codes have seen a rapid increase in the number and range of applications for which they are used in recent years, in part because they can be easily read by smartphones, tablets, and other mobile devices.
Current QQR code applications include:. The versatility, capacity, and accessibility of the QR code allows it to be used in a variety of unusual ways. QR codes have been included on artworks, stamps, money, tombstones, statues, museum exhibits, hiking trails, comic book covers, greeting cards — just about anywhere that they can fit and serve some kind of function. The patents for the QR code are held by Denso Wave a subsidiary of Denso, which is in turn owned by Toyota , which has chosen not to exercise its patent rights, and allows use of the codes without any license requirements.
In addition to QR code reading apps, free software and web-based services for generating QR codes are readily available.
It consists of a square of black and white cells or pixels with a locating symbol made of concentric squares directly in the center. This means that it does not require a blank quite zone or a boundary. The data is arranged in a spiral from the center out; each layer of the spiral is made up of two rings of pixels, adding four pixels to the total width.
An Aztec symbol with a compact core can have as many as 4 layers. A symbol with a full core can have 32 layers, and can encode over 3, digits, 3, characters of text, or 1, bytes of binary data. The Aztec code system is public domain, and applications are available for generating codes and reading them on mobile devices.
Given the similarity in design, readability, and capacity, Aztec codes could be used in many of the applications for which QR codes are becoming popular, although in practice, their use is more limited. Aztec codes are, however, fairly common in the transportation industry. They are used on airline electronic boarding passes, and for online and mobile railway tickets in many parts of Europe. In addition, they are used in the billing systems of several Canadian corporations, and the Polish government uses them in its car registration system.
A closer look shows another difference — instead of square pixels, the data is encoded in hexagonal dots which are arranged in a hexagonal pattern. MaxiCode was designed for a specialized function — routing and tracking United Parcel Service packages — and that continues to be its main use. Unlike the other 2D matrix codes described here, MaxiCode symbols have a fixed size approximately 1 inch square and a fixed amount of data that may be encoded approximately 93 characters, depending on the data mode.
As manyas 8 MaxiCode symbols may be linked, or chained together. There are five data modes in current use as well as two obsolete modes :. All of these modes may include a secondary message, which for UPS shipping usually contains more detailed shipping and tracking information.
In Modes 4, 5, and 6, the secondary message is effectively merged with the primary message. MaxiCode uses five code sets; a single message may switch between them repeatedly. Barcode Guide to Barcode Symbologies A barcode symbol is a machine readable image which conveys data.
