Bar Code Principles

• Element bar or space
• Barcount number of bars and spaces
• Start/Stop fixed patterns used to detect bar
  code

4
Bar Code Principles

• Resolution X module size width of the
  narrowest element in mm (mils in USA)
• Aspect Ratio bars height to symbols length
• Quiet Zone white margins (Overflow quiet
  zone time duration) Usually the Quiet Zone width
  must be 10 times X

Bar Code Basics

• What is a one D code?
• It is a sequence of dark and light elements. The
  code can be considered like an alphabet where
  each character is composed by a specific sequence
  of BARS and SPACES.

8
Common Linear Symbologies

• EAN/UPC
• Code 39
• Interleaved 2 of 5
• Code 128

9
BAR CODE BASICS

• What is a stacked code?
• The terms stacked symbology or multi-row code are
  applied to those codes composed by stacked rows
  of one dimensional bar codes. Each row is
  independently decoded, but the complete
  information is obtained appending the single
  content of all individual rows.

10
BAR CODE BASICS

• What is a matrix code?
• The term matrix code applies to 2D symbologies
  composed by black elements positioned in specific
  locations of a matrix. Each element has the same
  dimension, and the relative position of all
  elements in the matrix determines the information
  content of the code.

11
BAR CODE BASICS

• What is a composite code?
• It is the combination of a linear and a stacked
  code. Typically, the linear code identify the
  item, and the stacked code contains additional
  relevant information (i.e. production date,
  expiration date, batch number, etc.).

BAR CODE BASICS

• Why 2D codes?

• To reduce space

• To increase the quantity of information

14
SUITABLE APPLICATIONS FOR 2D CODES
there is lack of space
All applications in which
a lot of information is needed or there exist
need for portability of the code information

PICKET FENCE

• Barcode moves parallel to the scan line

17
STEP LADDER

• Barcode moves perpendicular to the scan line

18
INSTALLATION READING ANGLES

• Unattended laser devices are able to decode
  moving labels at a variety of angles, however
  significant angular distortion reduces reading
  performances
• When mounting the Scanner take care the 3 angles
  are near to the following ideal values
• Pitch 0
• Skew 10 to 30
• Tilt 0

19
READING ANGLES PITCH

• Position the reader in order to minimise the
  Pitch angle value P
• Too High of Pitch results in possibleOut of
  Focus effect!!

20
READING ANGLES SKEW

• To avoid the direct reflection of the laser light
  emitted by the scanner, place the reader assuring
  at least 10 for the Skew angle, S

21
Reading Angles TILT

• Place the reader in order to get the minimum Tilt
  angle value T

22
RASTER OSCILLATING LASER PATTERNS
or oscillating mirror (not for DS2100/2200)

• In PICKET FENCE applications the use of a raster
  scanner ...

• widens the reading surface.
• When figuring out the number of effective scans,
  it must be
• considered the percentage of scans actually
  crossing the bar code

23
ACR Code Recunstruction

• When the TILT angle is too big and the laser beam
  doesnt cross the label from the begin to the
  end, you need to use USS devices having the
  "Advanced Code Reconstruction" mode

27
2D Codes symbologies

• Two-dimensional code information along the
  height (X-axis) as well as the length (Y-axis) of
  the symbol
• No vertical redundancy
• 2D Codes tolerates printing dropouts because of
• Error Correction Capability (ECC)
• Increase the effective density of the encoding
  more data in a smaller space
• Portable database (rather than just a database
  key) encode complete data files in an optically
  readable symbol and so
• extend the potential market for AUTO-ID
• There are two types of 2D codes in current use
• Multi-Row (Stacked) codes
• Matrix codes

28
Matrix Symbologies (1/2)

• Matrix symbologies differ in terms of
• way input data is converted in binary pattern
• way pattern is placed on the greed
• grid size (number of cells)
• finder pattern
• Maximum data capacity
• up to 7089 numeric characters or 4296
  alphanumeric characters using Structure Append
  capability
• The most used Matrix codes are
• Data Matrix family
• QR Code
• Aztec Code
• Maxicode

29
Data Matrix ECC200 benefits

• Large amount of data
• High level of security
• High reading rate
• Low requirement for contrast
• Any printing technique
• Direct marking (silk screen printing, laser
  etching, etc.)
• Reduction of costs by using smaller labels
• Amount of data and size of the code are
  dynamically variable

30
Laser vs. Camera Comparison

• Camera/Vision Technology is Future Oriented
  Solution
• Benefits in Many Applications
• Image offers much more information
• Image Acquisition is creating New Functions that
  will modify the Logistic Process (VDC,
  Image Storage, )
