Laurer felt this was not acceptable. To make it worse as bars spread spaces shrink and vice versa. Requiring every bit width to be read precisely basically nullified the Delta C advantage except for the Delta C reference measurement. When one dimension is modified, the other dimension should be altered by a proportional amount. Compatible with iPhone, iPad, and iPod touch.

I used this in a shoe store that's supposed to have discounted merchandise. Their prices were high on a number of items I could find online for substantially less. I got this app today and I was excited to use it. It seemed like a cool app. I went to use it and every time I scanned something it always shown up as no matches. 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.
If you want to encode a URL into a barcode to make extended packaging information available to the end consumer, then you should use a GS1 2D symbol.
If you need to barcode an outer case to be scanned in a logistics environment, and you want to print directly on corrugated carton, ITF may be the choice for you.
The Barcode Lookup app gives you instant access to the millions of barcodes in our system, along with all the product info, descriptions, manufacturers and brands, customer reviews, photos, and . Barcode database sites or apps search the internet for information pertaining to the particular barcode number that has been entered or scanned. The information that is returned is generally company name and/or contact details, relevant product information or even . Scandit's UPC lookup tool searches our product database for any given UPC code. Scandit's solutions help bring barcode scanning technology to any industry.
