Representation from all industries GS1 India • Affiliated to GS1 International, Belgium controlling 103 GS1 organizations worldwide • GS1India is a not-for-profit organization under the Ministry of Commerce with its Board of members as follows : • FICCI • CII • ASSOCHAM • FIEO • SPICES BOARD • BIS • IMC • IIP • APEDA
GS1 Identification Numbers are KEYStto access computer files GS1dentification Numbers are . . . • Unique: every variant of an item is allocated a separate unique number • Non-significant: they identify an item but contain no information about it • International: GS1identification numbers are unique across all countries and all sectors • Secure: GS1 numbers are fixed length, numeric and include a standard check digit
Why do I need GS1 standards for identification ?
Problems faced with Proprietary Systems • Closed • Different formats • Carrier provided • Doesn’t enhance supply chain management • Evolved in the absence of standards - Multiple carriers = multiple systems
GS1 Numbering - Benefits • De-facto world standard • Based on universal and open standards • Tried tested and proven for 25 years • Enables product track and trace across the supply chain • Utility In Diverse Applications (inventory, sales mgmt etc). • Easier integration of product flow with information flow in supply chain
GS1 standards: National Priority • National IT Task Force recommendation no. 82 • EC/ EDI Council of India, Govt. of India, has declared GS1 standards as National stds. for EDI and barcoding http://commin.nic.in/doc/ecedi.htm#h1 • Registration subsidy for SSI and Tiny Sector • Suppliers to Canteen Stores Deptt., Army purchase organization, TASMAC, J&K Excise, Kerala state excise and other govt. deptts. required to source-mark products/ consignments through GS1 barcodes • Financial Assistance for registration provided by APEDA, MPEDA, Spices Board, MFPI • In line with ISO 15394 recommendation
GS1 Data Carriers (Barcodes) • GS1 identification numbers and other standard data are translated into barcode format and may be captured automatically by scanners. Scanners transmit data to computers for further processing. 5412345678908
Barcodes • Barcode is a series of parallel, adjacent bars and spaces used to encode the small strings of data • Barcoding provides the means for automatic data capture of information. • Barcoding when used with GS1 standards, it permits universal and unique identification of goods, services, assets etc. • A bar code reader(Scanner) decodes the bar code using intensity of the light reflected • Symbologies: • Linear Symbologies: EAN 13, UPC 12, ITF 14, GS1 128 • 2D Symbologies: PDF417 • Composite Symbologies

Barcode Implementation Flowchart for Product Types (SKU’s) Get registered with GS1 India and receive a company prefix Read the implementation guide book / CD provided with registration Using company prefix allocated by GS1 India generate product codes for each product type Forward the product codes to GS1 India for approval and International hosting by inputting them into GS1 India’sweb site www.gs1india.org.in Correct the Product code according to recommendations of GS1 India Have product codes been approved by GS1-India? No Yes
Barcode Implementation Flowchart for Product Types (SKU’s) Contd Yes Using the product codes , get your product packaging artwork modified to incorporate GS1 barcodes (if source marking is possible) or else incorporate barcodes in labels /tags. Send product packaging sample with barcode to GS1 India for “barcode verification report “ Carry out modifications in artwork based on scan report. Does the GS1 barcode scan satisfactorily ? No Yes Arrange for mass printing of product packaging or labels /tags using GS1 barcodes Inform all your supply chain partners about your product codes to enable them link GS1 codes product type with (SKU) and barcode scanning ( when ready)

Why are these simple black and white lines so important to us? The bars and spaces are technical requirements which when scanned get translated into a number.
TWO ISSUES…. Integrity & Quality
Verification (A Definition) Verification is a process to check how closely a barcode symbol adheres to its specifications and to highlight the ways in which it deviates from the ideal.
What Does it Mean? What are the Impacts if “NO”?
Consumer Units PRINT CONTRAST Very Important
Right Colors BLACK AND WHITE WORKS BEST
Right Colors YOU CAN SEE RED….. SCANNERS DO NOT !!!
What Does it Mean? MAGNIFICATION Can be slightly lower (no)- but at the expense of ease of scanning
Magnification?? 200% 80% Barcodes are based on a 100% magnification. The EAN13 standard allows for 80-200% to the nominal magnification. Basically, the bigger the better! 100% At 100%, the size is 37.3mm by 26.3 mm
What Does it Mean? HEIGHT OF BARS Can be slightly lower (no)- but at the expense of ease of scanning
Symbol Truncation Nominal Symbol • Symbols have a target height • Within the GS1 Symbology, there is a fixed relationship between the width [X-dimension] and height to enable omni-directional scanning • Truncation Limits POS scanning effectiveness • scanners read GS1 symbols as two halves and then piece the halves together into a complete number • shorter symbols decrease the opportunity to get a good scan • Do not truncate (shorten height) • truncate only when there is no room for the full symbol height Truncated Symbol 50
Height is “cutting” down the size - not the magnification Scanning Angle Range was Now
Reduction in height…. This OK for hand scanners, where you line up the barcode with a hand gun. But with Supermarket fixed scanners, you line up the product to the scanner.
What Does it Mean? LIGHT MARGINS Mandatory* Part of technical requirement
The space before and after the “barcode” is PART OF the barcode
Light Margins • UPC-A 9X - 9X • UPC-E 9X - 7X • EAN-13 11X - 7X • EAN-8 7X - 7X • ITF-14 10X - 10X • GS1-128 10X - 10X Left - Right 1 4 1 4 1 0 0 0 8 6 Light Margins
What Does it Mean? BAR WIDTHS There are very small tolerances, but to be safe need to be “YES”
BAR WIDTHS the bars and spaces are technical requirements which when scanned get translated into a number. Tolerance with 80% magnification ±13.5%. Tolerance with 100% magnification ±30%.
What Does it Mean? SYMBOL = NUMBER Mandatory
When the “bars and spaces” are scanned they must translate to the number below
What Does it Mean? CHECK DIGIT CALCULATION Mandatory
CHECK DIGIT Ensure the total number is “legal”
What Does it Mean? LOCATION OF THE CODE Impacts the ease of scanning
Curved Surfaces If a bar code symbol is printed on a curved surface, it is preferable for the barcodes to be in ladder type orientation (Bars of a barcode are parallel to the natural base of the product numbers reading from top to bottom). BACK
Watch for: - Hidden Barcodes, - Under flaps - Other printed material on the barcode - Next to seams or corners (on plastic packaged products) Checkout operators need to “find” it.
Who should verify? • Anyone who is handling barcode symbols should use verification. • The main classes can be:- • The printer who produces the symbol. • The person on whose product or item the barcode is being applied • The person receiving the barcoded item. • Persons handling the goods at intermediate stages of the supply chain.
Verification… Benefits! • The biggest benefits are simply reassurance and • confidence that the barcode symbol will perform • as intended at all stages of the product’s passage • down the supply chain. • Symbol producer is assured of the production • process of bar codes at his end. • No scanning problems at the receiver,s end. • - Leads to untroubled supplier – customer relationships.
Why not use a scanner? No two barcode readers (scanners) are the same.The optical arrangements available for scanners vary widely. Scanners show quite noticeable differences in their scanning performance. Two different scanners might have different degrees of success with the barcode symbol. Scanners provide no indication of symbol quality while verifiers measures and grades the quality of barcode symbol and can provide information to help diagnose the cause of problems where these occur.
Types of samples for verification. Ideally samples should be in their final form which allows more extensive testing in terms of colour,contrast,location, etc. Tests on loose labels or unfilled packages may not be reliable since applying labels or filling packages can sometimes affect the scanning performance due to the shape, the effects of filling colour showing through, package buldging, curvature of the products, etc.
