Barcode Quality: The Challenges
Verify the quality and long-term readability of codes marked by a variety of means:
Serialized barcodes printed
on labels or product packaging
Product codes printed directly
on secondary packagingParts directly marked with identifying codesSlide4
Pre-Printed
P
ackaging Materials:
Costly
inventory of pre-printed labels and
boxesEstimate: >/= 1.5 cents per label versus 0.002 cents per direct printNeed warehouse space for inventoryProduces scrap when product changesTime lost during product changeoverPrint-On-Demand Applications:Packaging is scrapped when there are unreadable printed codesDowntime associated with unreadable barcodes: manual data entry, re-scanning, relabelingSupply chain issues – customer fines, costly returns
Supplier disqualification due to lack of ISO compliance
Barcode Quality: The ChallengesSlide5
The Trouble with Today’s Methods
Offline verification
Problems with the marking method go undetected until next sample is verified offline
Scrap and downtime to determine scope of issue
Confirm readability using a barcode reader
Does not tell how well the code can be readDoes not analyze the code and provide dataDoes not provide trending analysis based triggersDoes not alert to a problem until there actually is one.Slide6
Verification measures the quality of a barcode to a published standard
ISO 15415/AIM DPM : 2D symbols
ISO 15416 : 1D symbols
Verification results are expressed in grades
4 / A =
perfect −
0
/ F = very poor
Machine vision verification is camera-based
Images are captured by the camera to be processed in detail by machine vision software
The Answer:
Machine Vision VerificationSlide7
Why Verify?
Because
all
marking systems degrade over time and once a code is marked, its quality
never
gets better!Without verification, some “bad” codes escape into the process.
With verification, we
prevent
bad
codes
from ever being
made.
Checking
that a code can/cannot be read is not good enough. It must be readable with an adequate margin.Slide8
Recommended Setups
True verification requires ISO/AIM-compliant light & undistorted image.
C-mount lenses preferred
Perpendicular mounting to avoid perspective distortion
Fixed distance
At
least 8 pixels per element
Shield from ambient light
A short (<250µs) exposure time for moving symbols

Why choose a Verification Kit over a turn-key Microscan Verifier?
Kits offer the same solution for both inline and offline verification
Kits verify multiple symbologies, rather than being customized to one set
Kits add other vision tools because they employ vision software
Kit software features multi-language supportSlide13

Comparison with Microscan VerifiersSlide14
Plug-in for Microscan AutoVISION® Machine Vision Software. Expands
on
capabilities
of
standard Microscan machine vision verification to provide trending
and detailed analysis of verification data.
Without verification, some “bad”
codes escape
into the
process.
With verification, we
prevent
bad
codes from
ever being made.PLUS – We can use trending with VMI to trigger alerts or actions based on code quality changes.
Verification Monitoring Interface (VMI)Slide15
Who does VMI benefit?
Manufacturers who utilize direct print methods to reduce
inventory costs of labels & boxes and downtime
associated with product changeovers.
What does VMI do?
Grades every code to verify it meets certain legibility criteria.Continuous process monitoring - catches any downward
trend in print quality so you can fix it before a material scrap or quality issue from unreadable codes.
Where is VMI implemented?
Inline as soon after marking as possible to minimize other variables.
Why should I use VMI?
More retailers and distributors are imposing fines for unreadable codes.

Frequently Asked Questions
Where do I get the VMI software?
VMI is available for download on the Microscan website to be used in Emulator mode (license key required to use on camera).
Is VMI a standalone software?
No
. Users must install AutoVISION® machine vision software before installing VMI. A custom version of AutoVISION is required, and is part of the VMI download package.Can VMI be used with existing hardware?Yes, on AutoVISION hardware with a software upgrade license. In order to meet barcode quality standards, VMI is not recommended for products with integrated lighting or optics. 98-000217-05, Verification & VMI License (A)Slide22
How fast is VMI?
Verification for trend monitoring is processing-intensive
and saving images and data taxes the smart camera even more
. With
the 2MP camera set to collect all images and data,
the maximum recommended speed is 30ppm. For faster speeds, the system can be configured to turn off image capture. The user may also need to use a lower-resolution camera such as the WVGA. Can human-readable text like date & lot codes be read using VMI? Yes, text can be read using AutoVISION OCR/OCV tools available through the VMI plug-in provided the data is within the FOV and you can still achieve the minimum 8 pixels per element.Frequently Asked QuestionsSlide23
Key Takeaways
Quality barcodes are critical for ensuring product tracking and identification
Code quality is affected by factors from degradation of marking methods to simple wear and tear
Confirming barcode readability by random offline sample checking or using barcode readers does not ensure 100% quality or long-term readability
Machine vision verification prevents bad codes from being made, preventing no-reads, scrap, downtime and customer finesSlide24
