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.
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.
Printing Methods Traditional : flexography and offset Digital : thermal and laser Direct Marking : e.

This symbol is guaranteed to be scanned by POS systems all over the world. If you are printing a barcode with variable information like serial numbers, expiry dates, or measures, then you will use GS , GS1 DataBar , or GS1 standardised 2D symbols.
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 standardised 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, GS or ITF may be the choice for you. More information See the GS1 barcodes page for an overview of the key characteristics for each of the GS1 barcodes.
Symbol sizes The X-dimension is the specified width of the narrowest element of a barcode. Here are some of the most frequently asked questions on HRI:. You must print 13 digits below the EAN Symbol. If you want to use other colours, the following may help you in choosing satisfactory ones: GS1 barcodes require dark colours for bars e. The bars should always consist of a single line colour and should never be printed by multiple imaging tools e.

One scan of a barcode can relay all of this information and trace the product back to the beginnings of its productivity, right down to the ingredients used to make it. Barcodes tell companies how many products they have, which can help them manage warehouse and inventory space better.
This cuts down on costs and ends up saving funds that would otherwise go to waste due to incorrect information. Laser scanners are the primary source used to read barcodes, whether they are stationary at a register or a mobile, handled scanner. LED lights scan over the black bars and white spaces, which then converts into text. The text is delivered to a software system that then reads and translates the information.
Without this space, the scanner would be unable to identify where the barcode begins and ends, making it incapable of reading the information. Deciding the right barcode to use means deciding what kind of information is being stored and communicated. There are 2 types of barcodes: 1-D and 2-D. Each type of barcode is able to hold a limited amount of information and is used in different industries world-wide.
The combinations result in particular patterns that make each barcode unique to each particular product. This also limits the amount of information they can carry. These barcodes are scanned at the point-of-sale with a handheld or stationary scanner.
The typical UPC-A barcode has 12 numerical digits, starting from left to right. The very first digit is known as a standard number system character. This number is assigned by GS1 and identifies a product category, either general or specific. The first set of 5 digits identifies the product manufacturer.
This number is specific to the company and remains the same on each item. The second set of 5 digits classifies that particular product. Each product will have its own unique number in this sequence. The last digit of the barcode is called the check number.
