Primary Focus

• Code 39

• Code 128

• UPC/EAN

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

But Many Types and ………

Many Scanner and Terminal Choices!

Plus Multiple Printer Decisions !

Endless Opportunities !

Bottom Line: Many Ingredients !

(If Practical)

Key Point:

Carbon Inks

• Print Contrast Signal (PCS)

Must Know the Difference Between

Dark Light

Carbon Inks

• Carbon vs. Alcohol/Dyed-Based Inks

Carbon Inks

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

Carbon Inks

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

Alcohol/Dye-Based Inks

Carbon Inks

• Hostile Environments (IR Scanner)

- Ultra Violet - Contaminents

Carbon Inks

Scanning PerformanceOften Better withCarbon Inks

Key Point:

Carbon Inks

• Major Exception: UPC/EAN in the Food

Industry

Media Substrate&

Adhesive Backing

Opacity

Media Substrate&

Adhesive Backing

• Opacity• Thermal Printers

- Direct- Transfer

Media Substrate&

Adhesive Backing

• Opacity• Thermal Printers • Adhesive Backing (Labels)

- Many Types (Permanent vs. Temporary)

Media Substrate & Adhesive Backing

Media RequirementsDepend on:

- Label Shelf Life- Scanning Frequency- Temperature & Humidity- Type of Surface

Key Point:

Verification

• Source Document to IT System

Which is

Better ?

“3 Yards and a Cloud of Dust”

Verification

• Poor Quality Media

1. Scanner Doesn’t Scan2. Scanner Scans Bad Data3. Bad Data from Scanning

Verification

• Definition

- Scannable

- Internal Application vs.

External Application

Manual Verification

plus or

(Internal)

Hand Held orOn-Line Verifiers

Verify to Standard

(external)

Verification

Quality Compliance (QC) can be achieved with Manual and Sophisticated Techniques

Key Point:

Scanner Resolution&

Media Density

Scanner Resolution & Media Density

Spot Size = 80% “X”

For Most Applications:

Lasers = 1 Model

Wands = 3 Models (Lo, Med, Hi)

Key Point:

Headache Time !

Bar Code Height

( Arching Motion )

Bar Code Quiet Zones

No Quiet Zones !

Code Height & Quiet Zones

Symbol Height Quiet ZonesCodes 39 & 128 Greater of:

.25” or 15% Length

Greater of:

.25” or 10 “X”

UPC/EAN 1.02” (Nominal) .117”

Key Point:

Numbering Schemes

• UPC/EAN is All Numeric(License Plate Approach)

Numbering Schemes

•Codes 39 & 128 are Alpha-Numeric(Code 128 can be Numeric Only)

Numbering Schemes

• UPC/EAN is All Numeric(License Plate Approach)

• Codes 39 & 128 are Alpha-Numeric

• Excessive Data Costs:- Money- Time- Accuracy

Numbering Schemes

Amend Current SchemesWhen Practical. Two Ways:

- Computer Input- Human Recognition

Key Point:

User Friendliness
