1. IN ANY OTHER WAY FOR IDENTIFICATION PURPOSES Positioning and orientation Two symbols need to be visible on outer cases one on a short side and the other on the adjacent side to the right in warehouse applications this enables consistent turning to ensure a label is visible On cases less than 1 metre in height The symbol should be no lower than 32mm from the bottom edge of the pack and no closer than 19mm to the nearest edge If a shrink wrap or multi pack is a traded item that is only going to be used in the distribution arena there should be two bar code symbols on the pack one on the front in the lower right corner and the other on the adjacent short side Picket fence orientation is preferred in all instances Shoprite Group of Companies 2008 Page 5 of 13 Cheekers v2 00e1 updated to GS1 GenSpec V8 Where the symbol is directly printed onto a heat shrunk film it must be positioned such that the shrinking process does not distort it any way or result in seams flaps or overlaps obscuring the symbol This practice is discouraged owing to the distortion resulting from the shrinking process Where the symbol is printed onto a separately applied label the label must be positioned in accordance with the edge rules and must not be wrinkled torn or distorted in any manner likely to result in a reduced scan rate For units greater than 1 metre in height excluding pallets labels should be placed so that all the symbols2. are at a height of between 400 mm and 800 mm from the base of the unit and no closer than 50 mm to the vertical edge Where an item is shrink wrapped it must be ensured that the film does not cover the bar code symbol in order to avoid specular reflectance Where it is not possible to avoid covering the symbol care must be taken to ensure that seams in the wrapper are not positioned over the symbols Magnification EAN 13 symbols on cases must be between 150 to 200 of nominal and should only be used if printed on labels or high quality corrugate Where an ITF 14 symbol is printed on a label and applied to the outer case the magnification need only be in the range 50 to100 of nominal For printing directly onto corrugate or other poor substrates ITF 14 symbols must be at a 100 magnification 4 8mm 10 2 mm d1 122 428 mm bey eS 41 41318 mm mm d2 152400 mm GS1 128 symbols should be printed at a minimum height of 32mm Show Through Under no circumstances must the bar code symbols printed on the single items contained within the shrink wrap or multi pack be able to be scanned To this end the contained items should either be packed with their individual symbols facing inwards or the over wrap must be opaque or printed with an obscuring pattern or the lip of the tray if used must be sufficiently high to fully obscure the symbols Thermal Labels Where a case or tray is marked by means of a label created on demand and

6. Bar Coding Standards for Items Supplied to the Shoprite Checkers Group Introduction Shoprite Checkers was one of the pioneers in the use of bar coding in the South African retail industry As this method of item identification and tracking has become more and more pervasive over time the reliance on it for improving not only logistics but also our customers overall shopping experience has escalated Whilst international standards have been published by the controlling body GS1 for the use of members of those bodies they have not been adequately enforced until now This has resulted in escalating costs to the Shoprite Checkers Group degradation in the quality of our customers shopping experience and a stumbling block in the path of increased usage of bar codes in automation of the logistics systems throughout the supply chain With the publication of the Shoprite Checkers requirements within our community of business partners we expect the unreserved adoption of and adherence to those standards by our trading partners for the mutual benefit of all parties There will be no exceptions or any relaxation of standards unless agreed to in writing by Shoprite Checkers Bar Code Quality management Scope The Shoprite Checkers Bar Coding Standards address the following areas e Use of appropriate symbology for a particular application o Symbols for retail units o Symbols for shrink wrapped retail units in the form of a multi pack that can
