Quality and Compliance

Are quality and compliance included in this trend? In fact, many companies view quality through a lens of compliance, and it for them, quality is all about numbers. The hard focus of that lens comes at a price: tight focus always limits the field of view. My apologies for the optical analogy, but it is apt.

Value is the bigger picture. When quality is compliance, it’s all about cost. Do just enough (the threshold) to justify the cost, and call that quality. Value, on the other hand, relates to business outcomes, risk reduction, resilience, customer trust, and sustainable growth. Through that lens, quality encompasses the business culture, relationships within the company and beyond, extending to upstream suppliers and downstream customers.

The AI Contribution

AI can contribute to capability, through processes and tools, but culture and leadership form the basis for consistency and trust, both within a company and outward to existing customers and, through effective, caring marketing, to new customers. AI can’t do that.

It’s a well-known fact that barcodes are the connective tissue that holds commerce (and substantially the entire economy) together. Barcodes support the manufacturing process, from upstream raw materials and subassemblies and through the assembly process: selecting and installing the correct parts to specification with a work order. Barcodes continue to identify the product and track its movement through the supply chain, from manufacturing through distribution to the end user. AI isn’t changing that.

Barcodes in a manufacturing process identify non-compliant upstream resources. Problems or opportunities for process improvement can be identified by the dwell time between barcode scans. Inventory debit and replenishment are a well-known process. AI might improve processes but barcodes provide the process performance data.

Barcode quality and compliance are best viewed from a value standpoint. The narrow view of cost leaves companies and people at risk. AI isn’t changing that either.

Where is the Value?

Cost is usually focused on the verifier and the person to operate it. Value, on the other hand, encompasses managing the risk of a faulty barcode, which endangers everything, from product repeatability in manufacturing, trace and track in the supply chain, inventory management and sale, and soon, post-sale user information. Value strengthens relationships within company teams and between companies that do business together. Value enhances the resilience of internal and external relationships by building trust. Relationships, resilience, and trust create sustainable growth. Value encompasses the big picture.

Value is slowly built and quickly destroyed

Barcodes that work right are critical in this big picture. A verifier is an essential tool. Risk-management tools require maintenance. Verifier calibration and recertification can be quick, inexpensive, and easy.

Compliance is a floor

Compliance is the ticket to the show. It’s not the box seat. A compliant barcode is good enough; it’s the threshold, the minimum bar required to avert rejection. Here’s what a compliant barcode isn’t:

• The best it could possibly be
• A confident assurance that the barcode will scan successfully on every scanner, everywhere, every time
• A declaration of consistency
• An indication of how far or near the barcode is from rejection

Compliance isn’t Reliability

In contrast, quality is about reliability under real-world conditions. Here is what quality addresses:

• Quality is grade headroom. Compliance is the floor. Quality reports where you are, from the floor to the ceiling
• Grade distribution over time. Quality evaluates consistency over time
• Parameter-level insight. Quality pinpoints specific attributes leading to the final barcode grade, so you know what’s working, what’s not working so well, and what to do about it.

Quality is a Range that starts with Compliance

It’s not a threshold, it’s a metric. A scale. We live in a world of uncertainty. Nothing is nailed down. While it’s helpful to know that a thing or a process is yielding a passing result, without deeper insight into how, when or why that thing or process will fail, we are running on hope.

Hope is a story based on unmeasured circumstances, feelings, attitudes and opinions. History does not predict the future. It’s a conspiracy of beliefs.  If it teaches us anything, it is to trust what can be measured. I gauges what is real. When we can detect change, we can learn to control it.

Quality is a Strategic Differentiator

Compliance isn’t quality. It is a subset of quality. And quality is not just about metrics. In its best sense, put to its best usage, quality is a strategic initiative in the fulfillment of a promise. Looking for a competitive differentiator? You just found the best one.

The post The Barcode Quality Conundrum appeared first on Barcode Test LLC.

Assume is an Acronym

That assumption is one of the most common — and costly — mistakes in product labeling.

A scan is not a test. It is only proof that one scanner, in one environment, on that particular day, managed to read the barcode. It says nothing about whether the barcode will perform reliably in a busy distribution center, on a retail checkout conveyor running at speed, in a hospital supply room under fluorescent lighting, or at a regulatory inspection where your records are under review. The scanner you used may be forgiving. The next one may not be.

Barcode verification is something different entirely. An ISO-compliant verifier doesn’t just read the barcode — it measures it. It evaluates contrast, print uniformity, element widths, structural integrity, and the margins surrounding the symbol, then grades each characteristic on a scale from 0 to 4. The result is an objective, documented quality score that tells you exactly how much performance margin your barcode has — and where it’s running thin.

What’s Actually at Stake

When a barcode fails in the field, the consequences range from inconvenient to serious.

For retail suppliers, non-compliant barcodes trigger chargebacks. Major retailers issue fines for barcode quality failures, and those fines arrive long after the shipment has been accepted and distributed. A verification program that catches a problem before the pallet leaves your dock costs a fraction of what one chargeback costs.

For manufacturers in regulated industries — medical devices, pharmaceuticals, food — the stakes are higher. The FDA requires that Unique Device Identifiers on medical devices be both accurate and scannable in the environments where they’ll be used. The Drug Supply Chain Security Act requires serialized barcodes that trading partners can verify throughout the distribution chain. A barcode that your scanner reads in the clean conditions of your production floor may fail in the real world, and that failure can mean a lot more than a returned shipment.

For anyone shipping into automated distribution, the risk is operational. Modern warehouses scan barcodes on high-speed conveyors, sometimes under challenging angles and lighting. A barcode grading at the minimum acceptable level in controlled conditions can fail those systems, causing mis-sorts, delays, and strained relationships with distribution partners.

The Straightforward Case

Verification does one thing that scanning cannot: it tells you your grade before your customer does.

A documented verification program creates a record that your barcodes met an objective standard at the time of production. That record protects you in chargebacks, supports regulatory compliance, and gives your quality team actionable data — not just a beep.

Most barcode failures are preventable. They trace to print settings, substrate choices, label artwork, or equipment wear — problems that verification surfaces early, when correction is cheap.

The question isn’t whether barcode quality matters. It’s whether you find out about a problem first, or your customer does.

The post Why Barcode Verification Matters — and Why a Scan Isn’t Enough appeared first on Barcode Test LLC.

21 CFR 820, which is, in fact, the US regulation, defines current good manufacturing practices. It requires manufacturers to establish a quality management system that monitors the entire process, from design and prototypes to production of the product in its final form. It also encompasses the entire product lifecycle. This is meant to ensure that the product is safe and effective when designed, made, shipped, received and put into use.

ISO 13485:2016 syncs US requirements with international standards. Previously, products sold globally had to comply with 21 CFR 820 in the US and ISO 13485 elsewhere, which meant separate audits, different quality management and documentation, and the associated higher costs (estimated at up to $500 million) due to these redundancies.

What problem does this solve?

Different nations had different requirements for medical device classes, adoption dates, and labeling. The alignment of 21 CFR 820 and ISO 13485:2016 makes the US FDA QMSR the template for most global regulators. There will always be outliers, but this minimizes and simplifies the safety and trace environment substantially. Furthermore, the FDA update requires Total Product Life Cycle (TPLC) on audits, which will now trace the UDI data through the entire design-build-market process. Checking the quality manual is no longer good enough.

What does this have to do with barcode quality and compliance?

It’s no longer good enough that the barcode looks good when printed. The audit now requires it to pass ISO print quality standards and validate the UDI data structure, including the correct item identifier and data field prefixes and other data characteristics. Since the UDI barcode is required to track the product or drug through its entire life cycle, from design and manufacturing to distribution and usage, barcode verification records are required for a TPLC audit.

More About Verification

There are two different FDA-accredited issuing agencies for UDI in the US: GS1 and HIBCC use different numbering conventions. The fact that both systems are FDA-approved does not mean either can be randomly selected. For example, if a TPLC investigator finds that a medical device was registered in the GUDID with an HIBCC structure but the packaging bears a GS1 formatted barcode, that is a traceable compliance failure, not just a printing error.

What Happens if a Barcode Fails?

TPLC produces a framework to trace the failure upstream, to the printer, graphics designer and even the data from the issuing agency. This strongly implicates verification: every step should involve a verifier and a report. This is particularly critical in GS1-compliant systems because the GS1 system is so complex, with data field prefixes, numeric-only and Alpha-numerical data fields and variable lengths. Even a minor encoding error—a wrong AI, missing field separator or truncated data can result in a symbol that looks OK but fails a verification (and audit) test. And of course, a GS1 barcode will not work in an HIBCC environment: know your distribution channel and what it expects.

The Bottom Line

The QMSR update and TPLC raise the stakes for GS1 and HIBCC and, therefore, for the product manufacturer. It’s no longer a matter of barcode quality and compliance only when the label is printed. The FDA requires that you demonstrate barcode quality and compliance throughout its entire life cycle. And you must have the verification data to prove it.

Nearly every hospital—98.7%–had an electronic barcode medication administration system. They own the technology, so you could conclude that adoption is essential in place. However, the same Leapfrog study found that only 34.5% of those hospitals have fully deployed the technology.

The Leapfrog Group sets the following standards for complete implementation:

Barcode-based medication tracking must be implemented in:

• 100% of their medical/surgical units
• 100% of their labor and delivery units
• 100% if their intensive care units
• Medications and patients must both be scanned in at least 9% of bedside medication dosing

The last requirement is where most failures occur, according to Leapfrog.

A related study by PubMedCentral (https://pmc.ncbi.nlm.nih.gov/) found that medication scanning rates range from 5.6% to 67%, and patient scanning varied from 4.6% to 89%.

Why are barcodes not getting scanned? One of the most commonly reported reasons?

The barcode was unreadable

Sick barcodes in hospitals–isn’t that ironic?

Why is this important?

• Medication errors are a significantly expensive liability
• Effective barcode medication administration reduces errors by nearly 50%
• Harmful errors dropped from 0.65 to 0.29 per 100,000 medications administered

Resolving and preventing barcode problems is important not only for patient safety and the cost of liability. Bad barcodes also encourage stressed healthcare workers to skip the scanning process altogether.

Resolving a barcode problem can be done quickly, easily, and inexpensively—if you know who to call.

How can you get your arms around that—what metrics are available that can actually put a number to that? The best one is probably barcode scanner sales, and that metric is described as “robust and broadly based.”

In 2023, the barcode scanner market was valued at $7.32 billion USD.  SkyQuest projects it will nearly double to $13.06 billion by 2032. That’s not unicorn territory, but neither is it a death knell. That’s steady, reliable, structural growth.

Wait a minute—how do sales of barcode scanners equate to the growth of barcode technology? Maybe more people are just scanning the same barcodes in more places. Although that could equate to growth in the use of barcode technology, there is documented expansion of new barcode adoption. Here are the fastest-growing sectors:

• Healthcare is currently the most dynamic, using barcodes to improve accuracy in patient identification, medication dosing, and inventory management. This is largely driven by concerns about patient safety and supply chain security. Barcodes are not only used in hospitals; clinics and labs are also adopting them. (Coherent Market Insights)
• Manufacturing is forecast to record the highest CAGR, supported by warehouse automation and evolving manufacturing techniques (Fortune Business Insights).
• E-commerce expansion, logistics, and the much-hyped retail Digital Link are major factors. (Intel Market Research)
• Retail represents over 30% of all barcodes scanned in 2025 and will likely remain the largest single segment.(Strategic Revenue Insights)

Is this just more of the same in the consumer-frantic West? Although North America remains the dominant market, Asia-Pacific is the fastest-growing region in the world, driven by strengthening manufacturing and an expanding retail presence.

OK, so no short-term bubble, but how about longer term? Will growth continue?

It looks likely.  Smart warehousing will be a major factor in the long and longer term. Then there is the GS1 Sunrise 2027. But healthcare will continue to be a powerful contributor, driven by FDA regulatory requirements.

Finally, don’t think of barcode scanning only as a handheld device. Scanners are increasingly positioned over conveyors and dock doors and mounted on forklift trucks. Soon, you will see scanners on warehouse robots and drones.

A barcode problem with a person holding a scanner is one scenario. A barcode problem somewhere in a million-square-foot warehouse is a different scenario.

Growth means barcode quality will remain important, and automation means the consequences of poor barcode quality will be higher than ever. Problems can be fixed but the damage is already done. Prevention is the gold standard.

The post Barcode Technology: How Much Longer? appeared first on Barcode Test LLC.

• Verification is an objective, ISO Standards-based evaluation of a barcode’s print quality. It’s like penmanship or legibility. If you can’t read it, it doesn’t matter if it’s brilliant.
• Validation checks the data content for correct prefixing and data-type. Some data fields have a fixed length, some allow encoding alphanumeric characters, and of course, the data must be correct. If it doesn’t make sense, being able to read it doesn’t matter.
  

  ---

To properly evaluate a barcode, both of these factors must be tested. A poorly printed barcode with perfect data fails; a well printed barcode with incorrectly parsed data fails. Compliance requires both to pass.

This is particularly important in highly regulated industries such as healthcare. But it is also important in less critical applications, like consumer goods. Even a lowly UPC has validation requirements for the encoded data. For example, if the barcode for vanilla-flavored yogurt is printed on a container of unflavored yogurt, the item sold and the re-inventory order are inaccurate.  Disrupting but not life-threatening.

Validation errors in healthcare and pharma are much more serious.

Proper barcode testing must include verification and validation.

Most (but not all) barcode verifiers also validate the data structure of a barcode.  Knowing the difference is the first and most important step in getting and staying compliant on your primary and secondary packaging.

A plain-language guide to the grading system behind 2D barcode quality

Most people who deal with barcodes professionally have heard the term “ISO grade” — a letter or number that tells you whether a symbol passed or failed a quality test. What almost nobody outside the verification industry can explain is what that grade is actually built from, or what physical printing problem each component is designed to detect.

That matters now more than ever. As companies transition to 2D symbols — Data Matrix codes for medical devices and pharmaceuticals, QR codes for retail and GS1 Digital Link compliance — they are running into quality failures they didn’t anticipate. The symbols look fine. They scan on the test scanner at the print station. And then they fail at the point of care, at the automated warehouse conveyor, or at the retail point of sale. The grade would have told them why. But only if they understood what the grade was measuring.

ISO/IEC 15415 is the international standard that defines how 2D barcode symbols — primarily Data Matrix and QR Code — are graded. It specifies seven parameters, each of which isolates a different dimension of print quality. The overall grade is the lowest grade among all seven. Think of it as the weakest link: a symbol that scores A on six parameters but D on one still receives a D.

Here is what each parameter measures, why it exists, and what print defect it is designed to catch.

Parameter 1: Decode

What it measures: Can the symbol be decoded at all?

This is the most fundamental test, and the only one that is strictly pass/fail. The verifier attempts to decode the symbol using a reference decode algorithm — a standardized software decoder designed to be consistent across measurements, not optimized for real-world tolerance. If the symbol decodes, this parameter passes with a grade of 4 (equivalent to A). If it does not decode, the entire symbol receives a failing grade regardless of how well it scores on every other parameter.

Why it exists: A symbol that cannot be decoded by the reference algorithm has failed at the most basic level. No amount of good contrast or clean geometry can compensate for a symbol that simply cannot be read. Decode failure typically indicates severe module damage, catastrophic ink spread, or fundamental printing errors such as a skipped print head element that leaves an entire column of modules missing.

The practical catch: Decode failure is usually obvious. The more insidious quality problems are the ones that pass decode but degrade the other six parameters — producing a symbol that can be read under ideal conditions but fails under the real-world scanning environments your supply chain actually contains.

Parameter 2: Symbol Contrast

What it measures: The difference between the lightest and darkest areas in the symbol, expressed as a percentage of the total reflectance range the verifier can measure.

Symbol Contrast is calculated as R-max minus R-min — the reflectance of the lightest element minus the reflectance of the darkest element. A symbol printed in dense black ink on bright white label stock will show a large contrast value. A symbol printed on a colored substrate, a glossy surface, or with faded ink will show a much smaller one.

Why it exists: Scanners decode barcodes by detecting the transition between light and dark. The larger the contrast difference, the more reliably a scanner can distinguish a dark module from a light one. When contrast is low, the signal the scanner receives is ambiguous — marginal illumination angles, slight surface variations, or minor label damage can push a module’s reflectance to the wrong side of the threshold, causing a misread.

The practical catch: Symbol Contrast catches problems that are invisible at normal inspection distances. A label that looks perfectly printed under the fluorescent light at your receiving dock may have dangerously low contrast under the near-infrared illumination many industrial scanners use. A verifier measures contrast under calibrated, standardized conditions — the human eye cannot replicate this reliably.

Parameter 3: Modulation

What it measures: How consistently each individual module achieves its intended reflectance value, relative to the overall contrast range of the symbol.

Where Symbol Contrast measures the distance between the lightest and darkest elements overall, Modulation looks at whether the individual dark modules are consistently dark and the individual light modules are consistently light. A symbol can have acceptable overall contrast but poor Modulation if some dark modules are printing lighter than others — perhaps because of ink starvation in one region of the label, thermal print head wear, or substrate texture variation.

Why it exists: A decoder determines whether a given module is dark or light by comparing its reflectance to a threshold — typically the midpoint between R-max and R-min. If a dark module’s reflectance is closer to the midpoint than it should be, there is less margin for error. Any real-world degradation — a scratch, a smudge, variable lighting — can push that module past the threshold and cause a misread.

The practical catch: Low Modulation is a leading indicator of print process instability. It often reveals ribbon age, substrate inconsistency, or print head condition problems before they become visible as defects or cause scan failures. Catching low Modulation early is considerably cheaper than a product recall or a compliance rejection.

Parameter 4: Fixed Pattern Damage

What it measures: The integrity of the structural elements the decoder uses to locate, orient, and interpret the symbol — the finder pattern, quiet zone, timing patterns, and alignment patterns.

Every 2D symbology has regions that serve not as data storage but as navigation aids for the decoder. In a Data Matrix symbol, these are the solid “L” shaped border (the finder pattern) and the alternating light-dark border opposite it (the timing pattern). In a QR Code, they are the three large square patterns in three corners, plus the alignment patterns distributed throughout larger symbols. Fixed Pattern Damage measures how intact these structural elements are.

Why it exists: A decoder that cannot locate or orient the symbol cannot read it, regardless of how well the data modules are printed. Fixed Pattern Damage is graded more harshly than damage to data modules because of this asymmetry: the error correction built into 2D symbols can reconstruct damaged data modules, but it cannot compensate for a corrupted finder pattern.

The practical catch: Fixed Pattern Damage is often caused by die-cutting, perforation, or folding lines that happen to intersect the finder pattern. It can also result from label applicators that smear ink across the leading edge of the symbol during application. Because the finder pattern is located at the symbol’s border, it is disproportionately exposed to physical handling damage — exactly the kind that accumulates between print and final scan.

Parameter 5: Axial Non-Uniformity

What it measures: Whether the symbol’s modules are consistently sized and spaced along both the horizontal and vertical axes, or whether the symbol is stretched or compressed in one direction relative to the other.

Axial Non-Uniformity compares the module pitch — the distance from the center of one module to the center of the next — along the X axis versus the Y axis. A well-calibrated printer produces modules that are square and evenly spaced in both directions. A printer with a high speed setting, a worn platen roller, or a label web that stretches during printing will produce modules that are elongated in one direction. The symbol looks like a rectangle when it should look like a square grid.

Why it exists: Decoders are designed to handle some degree of symbol distortion, but Axial Non-Uniformity beyond tolerance forces the decoder to make assumptions about module placement that increase the likelihood of misread. The effect is most damaging in larger symbols with more modules, where the accumulated positional error across the symbol becomes significant.

The practical catch: Axial Non-Uniformity is almost never visible to the naked eye at the distances typical of label inspection. It requires measurement. It is a common failure mode for thermal transfer printers that have not been calibrated recently, and for continuous-feed printing operations where web tension varies across a print run.

Parameter 6: Grid Non-Uniformity

What it measures: How accurately the center of each individual module falls on the ideal reference grid that the decoder expects.

Where Axial Non-Uniformity measures systematic distortion across the whole symbol, Grid Non-Uniformity measures local, random variation in module placement. Even if the overall symbol dimensions are correct, individual modules can be shifted from their ideal positions by substrate texture, print head element variation, vibration in the print mechanism, or thermal expansion during printing. Grid Non-Uniformity captures this noise.

Why it exists: A decoder reconstructs the symbol by projecting a reference grid onto the image and sampling the reflectance at each expected module location. If a module’s center has shifted, the sampling point falls on the wrong location — possibly on the border between a dark and a light module — and the decoder misclassifies it. High Grid Non-Uniformity means the decoder is operating with less geometric certainty at every module in the symbol.

The practical catch: Grid Non-Uniformity failures often indicate substrate problems: embossed or textured label materials that physically deflect the print head during printing, or substrates with inconsistent surface absorption that cause ink to spread unevenly. It is also a common symptom of printing on curved or irregular surfaces — which is precisely where direct part marking (DPM) on medical devices or industrial components tends to occur.

Parameter 7: Unused Error Correction

What it measures: How much of the symbol’s built-in error correction capacity remains available after accounting for any damage or degradation the symbol has already sustained.

2D matrix symbologies encode data redundantly. A Data Matrix or QR Code can still be decoded even if a portion of its modules are unreadable, because the error correction algorithm can reconstruct the missing data from the surviving modules. Unused Error Correction measures what percentage of that correction capacity is still intact. A symbol with no damage has 100% of its error correction available. A symbol with some print defects has consumed some of that capacity to compensate for those defects — leaving less margin to absorb future damage during handling and distribution.

Why it exists: A symbol that arrives at its destination with 100% of its error correction intact is not the same as a symbol that barely survived the trip. Both may scan successfully today, but the latter has no remaining tolerance for a scratch, a moisture mark, or a partial obstruction. Unused Error Correction answers the question: how much more damage can this symbol absorb and still be readable?

The practical catch: This parameter directly translates to supply chain resilience. A pharmaceutical label that leaves the printer with a C-grade Unused Error Correction score may scan at the dispensing cabinet — until a drop of water, a handling smear, or a storage crease consumes the remaining capacity. The consequence in a clinical setting is not a failed checkout transaction. It is a scanning failure at the point of medication administration.

How the Parameters Combine Into a Grade

Each parameter is scored on a scale of 0 to 4, where 4 corresponds to a letter grade of A and 0 corresponds to F. The overall symbol grade is the lowest score among all seven parameters — not an average.

This is intentional and significant. A symbol cannot compensate for a critical weakness in one dimension by excelling in others. A symbol with perfect contrast, geometry, and error correction capacity but a damaged finder pattern still fails. This mirrors the real world: a scanner attempting to read that symbol will be stopped by the one thing it cannot work around, regardless of everything else the symbol has going for it.

The grade thresholds are:

Many retailers, healthcare, and pharmaceutical compliance programs specify a minimum grade of 1.5 (between C and D) or higher. GS1 recommends a minimum grade of 1.5 for retail applications; healthcare applications under FDA UDI requirements and pharmaceutical serialization under DSCSA typically require higher minimums and may be specified by the trading partner or regulatory body.

What This Means in Practice

The value of understanding these seven parameters is not academic. Each one points to a specific, addressable root cause in the print process. A Symbol Contrast failure points to ink density or substrate selection. An Axial Non-Uniformity failure points to printer calibration. A Fixed Pattern Damage failure points to die-cutting registration or applicator alignment. Grid Non-Uniformity failures point to substrate or print head condition. Unused Error Correction failures tell you that the symbol is absorbing damage somewhere in the process between print and scan.

A scan test tells you only whether a particular scanner, under particular conditions, could decode the symbol at the moment you tested it. An ISO grade tells you why the symbol performs the way it does, and what margin remains between current performance and failure.

As 2D barcodes become mandatory across retail, healthcare, pharmaceutical, and food supply chains, the difference between those two kinds of information is the difference between reactive troubleshooting and systematic quality control.
