In many cases the symbol background is not printed and the colour of the packaging substrate is used as barcode background.
The size of the symbol within the design will depend on the symbol specified, where the symbol will be used, and how the symbol will be printed.
The X-dimension is the specified width of the narrowest element of a barcode. X-dimensions are used together with the symbol heights to specify the permissible symbol sizes. For each scanning environment the relevant symbols are listed with their target X-dimension and corresponding target height.
Besides the target sizes also the allowed minimum and maximum sizes are specified. There is a fixed relationship between symbol height and width. When one dimension is modified, the other dimension should be altered by a proportional amount. The final major consideration for symbol size is the capability of the selected printing process. The minimum size magnification and correct Bar Width Reduction BWR for a symbol varies by printing process and even from press to press.
Printing companies should establish a minimum symbol size magnification and BWR to achieve acceptable and repeatable quality results. Symbol Specification Table 1 provides the details for the retail point-of-sale scanning environment.
The text beneath a barcode, called Human Readable Interpretation HRI , is important because if the barcode is damaged or of poor quality to begin with, then the text is used as a back-up. HRI should be placed below the barcode and grouped together wherever physically possible while maintaining the HRI legibility and minimum barcode height. I see parentheses around the Application Identifiers AI under some barcode symbols. Are they supposed to be there and are they encoded in the bars and spaces of the symbol?
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 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 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 the feed direction of the web or sheet.
When using flexographic printing, the bars should run parallel to the press direction. If the bars are required to run perpendicular to the press direction check to ensure the symbol is not distorted. When using either silk screen or rotogravure printing processes, the symbol should be aligned parallel to the cell structure on the screen or gravure plate cylinder to provide the smoothest bar edge possible. To determine the proper location for GS1 barcodes refer to the placement rules in section 6 of the GS1 General Specifications.
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 standardized test to determine whether applicants qualify for admission.
Several universities may utilize the same standardized test, but each sets the minimum score necessary for its applicants to be admitted. GS1 General Specifications Section 5 provides 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 Members may choose to perform their own quality control of barcode production.
Today, many GS1 Member Organisations offer barcode quality verification services. Find your local member organisation: Introduction The most important implementation resource for barcode identification are the over GS1 Member Organisations in countries all around the world. Ten Steps to Barcode Implementation.
More information See the GS1 Identification Keys page for short introductions on the role and characteristics for each of the GS1 keys. Select a barcode printing process To begin, you should decide what you are barcoding and if the barcode will carry static or dynamic information inside it.
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. If the product only requires text and a barcode with dynamic data, a label could be printed inline and applied to the package automatically if high volume or by hand if low volume. It could also be printed directly on the package itself without using a label.
Also a barcode with static data could be printed directly on the package using a digital printing method, for example when the same packaging is used for different products. More information Your local GS1 Member Organisation is there to assist you in making the right selection, and many Member Organisations can also help you find a printing company in your local area. Select a "primary" scanning environment The specifications for barcode type, size, placement, and quality all depend on where the barcode will be scanned.
Select a barcode Selecting the right barcode is critical to the success of your barcode implementation plan, but here are some high level tips: This symbol is guaranteed to be scanned by POS systems all over the world. In some cases GS1 DataBar symbol may be applied.
But one commonly overlooked portion of the label can provide all this information and more. Locate the UPC or bar code. The UPC bar code of an item is usually found printed on the label or package of an item. Because the bar code allows fast product entry at the cash register, this information is always found in an easily accessible spot on the outside of a product.
In some cases, such as clothing items, it is printed onto a removable tag. In other instances, it is printed onto the product itself. If the bar code isn't immediately visible, check the back and underside of the product. Write down the UPC number. In addition to the black-and-white bar code, there should also be a number. This number is the same number that the bar code represents, but the bar code presents this number in a machine-readable format. The UPC number will usually be either eight or 12 digits in length, but 13 digit codes are not uncommon.
If the number is not the correct length or if it contains characters other than regular numbers, it's not a UPC bar code number. Check the UPC in an online database.
