Businesses & organizations are
constantly producing barcodes
Consistency is required to simplify
the flow of information in supply
chain
=> Standards are created

ISO stands for International Organization
for Standardization
"A standard is a document that
provides requirements, specifications,
guidelines or characteristics that can
be used consistently to ensure that
materials, products, processes &
services are fit for their purpose"
barcodelive.org

6.
There are 3 ISO standards that address barcode quality
ISO 15416
for 1D barcodes
ISO 15415
for 2D label-based barcodes
ISO/IEC TR 29158, or AIM DPM
for 2D DPM codes

This ISO standard is for 1D barcodes
If a scan line fails minimum reflectance,
decoding, or minimum edge contrast, a "F" grade
is automatically assigned
If all 3 pass, the program ranks the parameters
of symbol contrast, modulation, flaws, and
decodability

Minimum
Reflectance
Edge Contrast
Modulation
Decode
Defects
Decodability
Check if the bars are dark enough to meet the required
ratio of light reflected off of the spaces.
Measure difference between adjacent bars & spaces
Refer to local variations in contrast
Check if the code can be read using standard reference
decode algorithm
Include printing errors, dirt, or markings that affect one
single bar or space
Grade the accuracy of bar and space widths compared to
their ideal size

10.
This ISO standard evaluates 2D barcodes
The grading procedure begins with a pass/fail
test. If the code can be decoded, the first
condition is passed
If it cannot, it is automatically given a "F"

Symbol
Contrast
Modulation
Fixed Pattern
Damage
Axial Non-
uniformity
Grid Non-
uniformity
Refer to the difference between the darkest & lightest
modules
Measure local variations in contrast
Include errors with the L sides or clock pattern or quiet
zone
Refer to the uneven scaling of the code
Measure the biggest deviation from the grid

12.
The quality parameters and grading process for DPM codes are
similar to ISO 15415
AIM DPM calculates global threshold using a more
sophisticated algorithm than ISO 15415 to accommodate a wide
range of background surfaces

GS1 is the barcode standards used
by retailers, manufacturers, &
suppliers
GS1 specifies general & particular
bar code standards for
identification, data collection,
exchange, & usage
