5. 1. Low Density (CPI) 2. Wide to Narrow Bar Ratio (WNBR) 3. Carbon Ink 4. Media Substrate & Adhesives 5. Verification 6. Scanner Resolution & Media Density 7. Bar Code Height & Quiet Zones 8. Numbering Schemes 9. User Friendliness 10. Support Source

6. Primary Focus Code 39 Code 128 UPC/EAN

7. Not A Single Label........

8. But Many Types and ………

9. Many Scanner and Terminal Choices!

10. Plus Multiple Printer Decisions !

11. Endless Opportunities !

12. Bottom Line: Many Ingredients !

13. Low Density SYMBOL “X” Factor (Narrowest Element Size).020 ".013 ".010 ".0075 " Characters Per Inch (95% of All Applications)

14. Low Density SYMBOL “X” Factor (Narrowest Element Size).020 ".013 ".010 ".0075 " Code 393-45-66-78-10 Characters Per Inch

15. Low Density SYMBOL “X” Factor (Narrowest Element Size).020 ".013 ".010 ".0075 " Code 393-45-66-78-10 Code 128 (A/N) 4.67.09.112.1 Characters Per Inch

16. Low Density SYMBOL “X” Factor (Narrowest Element Size).020 ".013 ".010 ".0075 " Code 393-45-66-78-10 Code 128 (A/N) 4.67.09.112.1 Code 128 (N) 9.114.018.224.2 Characters Per Inch

17. Low Density SYMBOL “X” Factor (Narrowest Element Size).020 ".013 ".010 ".0075 " Code 393-45-66-78-10 Code 128 (A/N) 4.67.09.112.1 Code 128 (N) 9.114.018.224.2 UPC/EAN51012- Characters Per Inch

19. Low Density Implement with the Lowest Practical Density Key Point: BIGGER is Better !

20. Wide to Narrow Bar Ratio (WNBR) Elements: UPC/EAN = 1:1 and 2:1 and 3:1 and 4:1 Code 128

21. Wide to Narrow Bar Ratio (WNBR) Narrow Wide (2 to 1) Wide (3 to 1) Code 39 Elements: Range

22. Wide to Narrow Bar Ratio (WNBR for Code 39) Narrow.010 inch Wide (2 to 1).020 inch Wide (3 to 1).030 inch

23. Wide to Narrow Bar Ratio (WNBR for Code 39) NARROW Bars/Spaces GROW 30% WIDE Bars/Spaces SHRINK 30%

24. Wide to Narrow Bar Ratio (WNBR for Code 39) Narrow.010 inch.013 inch (+ 30%) Wide (2 to 1).020 inch.014 inch (- 30%)

25. Wide to Narrow Bar Ratio (WNBR for Code 39) Narrow.010 inch.013 inch (+ 30%) Wide (2 to 1).020 inch.014 inch (- 30%) Wide (3 to 1).030 inch.021 inch (- 30%)

26. Wide to Narrow Bar Ratio (WNBR) For Code 39, Implement WNBR = 3:1 (If Practical) Key Point:

27. Carbon Inks Print Contrast Signal (PCS) Must Know the Difference Between DarkLight

28. Carbon Inks Carbon vs. Alcohol/Dyed-Based Inks

29. Carbon Inks Carbon vs. Alcohol/Dyed-Based Inks All Scanners Scan with Carbon Inks

30. Carbon Inks Carbon vs. Alcohol/Dyed-Based Inks All Scanners Scan with Carbon Inks Not All Scanners Scan with Alcohol/Dye-Based Inks

31. Carbon Inks Hostile Environments (IR Scanner) - Ultra Violet - Contaminents

32. Carbon Inks Scanning Performance Often Better with Carbon Inks Key Point:

33. Carbon Inks Major Exception: UPC/EAN in the Food Industry

34. Media Substrate & Adhesive Backing

35. Opacity

36. Media Substrate & Adhesive Backing Opacity Thermal Printers - Direct - Transfer

37. Media Substrate & Adhesive Backing Opacity Thermal Printers Adhesive Backing (Labels) - Many Types (Permanent vs. Temporary)

39. Media Substrate & Adhesive Backing Media Requirements Depend on: - Label Shelf Life - Scanning Frequency - Temperature & Humidity - Type of Surface Key Point:

40. Verification Source Document to IT System Which is Better ?

41. “3 Yards and a Cloud of Dust”

42. Verification Poor Quality Media 1. Scanner Doesn’t Scan 2. Scanner Scans Bad Data 3. Bad Data from Scanning

43. Verification Definition - Scannable - Internal Application vs. External Application

44. Manual Verification plus or (Internal)

45. Hand Held or On-Line Verifiers Verify to Standard (external)

46. Verification Quality Compliance (QC) can be achieved with Manual and Sophisticated Techniques Key Point:

47. Scanner Resolution & Media Density

48. Scanner Resolution & Media Density

50. SpotVoid

51. Scanner Resolution & Media Density Spot Size = 80% “X” For Most Applications: Lasers = 1 Model Wands = 3 Models (Lo, Med, Hi) Key Point:

52. Headache Time !

53. Bar Code Height ( Arching Motion )

54. Bar Code Quiet Zones

55. No Quiet Zones !

56. Code Height & Quiet Zones SymbolHeightQuiet Zones Codes 39 & 128Greater of:.25” or 15% Length Greater of:.25” or 10 “X” UPC/EAN1.02” (Nominal).117” Key Point:

57. Numbering Schemes UPC/EAN is All Numeric (License Plate Approach)

58. Numbering Schemes Codes 39 & 128 are Alpha-Numeric (Code 128 can be Numeric Only)

59. Numbering Schemes UPC/EAN is All Numeric (License Plate Approach) Codes 39 & 128 are Alpha-Numeric Excessive Data Costs: - Money - Time - Accuracy

61. Numbering Schemes Amend Current Schemes When Practical. Two Ways: - Computer Input - Human Recognition Key Point:

62. User Friendliness First Pass Read Rate(80+%)

63. User Friendliness First Pass Read Rate(80+%) Second Pass Read Rate(95+%)

65. Going Home !!!

66. User Friendliness Training & Confidence

67. Four-Step Training Program 1. Review Current Transaction Procedures - A Confidence Builder

68. 1. Review Current Transaction Procedures 2. Provide Benefits of Bar Coding - SELL! Four-Step Training Program - A Confidence Builder

69. 1. Review Current Transaction Procedures 2. Provide Benefits of Bar Coding - SELL! 3. Simulate New Transaction Procedures Four-Step Training Program - A Confidence Builder

70. 1. Review Current Transaction Procedures 2. Provide Benefits of Bar Coding - SELL! 3. Simulate New Transaction Procedures 4. Introduce Contaminated Media Four-Step Training Program - A Confidence Builder

71. User Friendliness Use “Data or Application Identifiers”

72. Data or Application Identifiers

73. Data Identifiers

74. Application Identifiers SSCC (Serial Shipping Container Code)

75. Data Identifiers (DI’s) Application Identifiers (AI’s) DI’s = 1 alpha and up to 3 numeric characters AI’s = 1 to 4 numeric characters

76. Data Identifiers (DI’s) Application Identifiers (AI’s) DI Source: ANSI Document MH 10.8.2 ANSI:212-642-4900 or www.ansi.orgwww.ansi.org AI Source: Uniform Code Council Document UCC 4 UCC:937-435-3870 or www.uc-council.org

77. User Friendliness Best Test of Implementation is Measured at Point-of-Scanning Key Point:

78. Support Source Quality Suppliers are Available - Hardware - Software

79. Support Source Quality Suppliers are Available - Hardware - Software Total Systems Expertise is Required - Planning - Training - Implementation

80. Support Source Data Capturing Techniques Should be Fully Integrated Into Information Technology Systems! Key Point:
