  • 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
gs1dentification numbers are

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
slide5

Why do I need GS1 standards

for identification ?

problems faced with proprietary systems
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
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
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 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.

barcodes
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

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

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)

Topics to be covered

Barcode Verification

slide21

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.

slide22

TWO ISSUES….

Integrity

&

Quality

verification
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.

slide24

What Does it Mean?

What are the Impacts if “NO”?

slide25

Consumer Units

PRINT CONTRAST

Very Important

SEE RED…..

SCANNERS

DO NOT !!!

slide28

What Does it Mean?

MAGNIFICATION

Can be slightly lower (no)-

but at the expense of ease of scanning

slide29

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

slide31

What Does it Mean?

HEIGHT OF BARS

Can be slightly lower (no)-

but at the expense of ease of scanning

symbol truncation
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

slide33

Height is “cutting” down

the size - not the magnification

Now

slide34

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.

slide35

What Does it Mean?

LIGHT MARGINS

Mandatory*

Part of technical requirement

slide36

The space before and after

the “barcode”

is PART OF the barcode

What Does it Mean?

BAR WIDTHS

There are very small tolerances,

but to be safe need to be “YES”

slide39

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%.

slide40

What Does it Mean?

SYMBOL = NUMBER

Mandatory

slide41

When the “bars and spaces”

are scanned they must translate

to the number below

slide42

What Does it Mean?

CHECK DIGIT CALCULATION

Mandatory

slide43

CHECK DIGIT

Ensure the total number is “legal”

slide44

What Does it Mean?

LOCATION OF THE CODE

Impacts the ease of scanning

curved surfaces
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

slide46

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
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.
benefits

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
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
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.

why get an official gs1 verification report
Why get an official GS1 verification report.

Only GS1 official verification reports are accepted by Delhi State Excise and some foreign buyers. Australia and New Zealand in particular. In all likely-hood a lot of other retail chain stores in India are likely to adopt this as a standard requirement.

In addition to the ANSI/CEN standards, the official GS1 verification test assesses specifications like the correct type of symbology, the correct size, bar height, location, correctness of representation of human readable numbers, etc

in short
In short

Verification assures everyone in the supply chain that barcodes will perform as intended.

how does gs1 india do it
How does GS1 India do it.

We use verifiers from Axicon Sea ID Verifier PC 6000 series for EAN – 13 / UPC –A/ EAN - 8 barcodes and Verifier PC 7000 for other barcodes like GS1 – 128/ITF – 14 / SSCC and other barcodes.

A demonstration now will show you the capabilities and usefulness of the equipment being used.

Flowchart for Barcoding on cartons for Inventory and Distribution Management

Analyse your business process to decide on the data to be barcoded in the supply chain management and relevant changes to be made in the application software

Generate the GTIN - 14 codes for packages

  • Choose a symbology for barcoding your trade unit level items (cartons , boxes etc ). Suggested symbologies:
          • ITF 14
          • GS1 -128
  • Decide on Printing technique. Options of printing are:
    • a) If ITF 14 ,the suggested option is
    • - Pre print on cartons through one time change in artwork of cartons
    • b) If GS1 -128 the two options are
      • i) Inhouse printing of labels ( Requirement : barcode printer and consumables )
      • ii) Outsource barcode labelling requirement to a barcode printing company

Flowchart for Barcoding on cartons for Inventory and Distribution Management

Print a sample barcode or packaging material with barcode it to GS1-India for barcode verification report.

Carry out modifications based on scan report.

Does the GS1 barcode

scan satisfactorily ?

No

Yes

Enable your software for the barcode symbology you are using and get scanners installed. Start scanning the barcodes at trade unit level for Receipt, dispatch, warehouse and inventory management of goods.

Inform all your trading partners in the supply chain about the symbology [ In case of GS1-128 also about AI’s] used by you at trade level so that they can also scan the barcodes in supply chain management.

slide58

!!! Important !!!

  • The GS1-128 bar code symbol has a variable length BUT:
    • not more than 48 data characters can be encoded
    • the physical length can not exceed 165mm
logistics unit60
Logistics Unit
  • The term Logistic Unit refers to shipping containers such as pallets. The GS1 system has numbering and labeling conventions known as Serial Shipping Container Code (SSCC) for use by transport,distribution and warehouse operators.
  • Symbology : GS1-128 including SSCC
  • SSCC is a voluntary standard for the numbering and bar coding of logistic units.
gs1 logistics label sscc
GS1 Logistics Label & SSCC
  • The SSCC is the only mandatory field of the label.
  • Label uses GS1-128
  • The SSCC individually identifies the logistic unit to which it is applied for the lifetime of that unit.
  • Information contained
    • Unit identification (SSCC)
    • GTIN (Identification number of trade unit)
    • Additional manufacturing information (dates, batch number,...)
  • Consignment number, location number,...
  • Order information
