Creating the Perfect QR Code Labels

From tracking packages to enhancing restaurant menus, QR code labels are everywhere. Why? Well, they store more data than traditional barcodes and can be scanned easily with a smartphone or standard scanner.

Even large corporations like Android and Amazon use QR code stickers to build their brand and deliver important information to their customers, streamlining everything from checkout processes to shipping labels. Those snazzy QR code labels can elevate your small business, too.

Let’s get into the details of using readable, fast, and effective QR labels.

Quick Background on QR Codes

QR codes are two-dimensional barcodes originally used in the automotive industry to manage parts more efficiently with fast, scannable codes. They gained popularity across industries thanks to their high data density (supporting numeric, alphanumeric, binary, and kanji encoding) and ease of use.

A QR code label can contain everything from product info to links that open web pages with a quick scan. They’re often generated with QR code generator tools.

The first QR code standard was created for auto parts in 1997. It was followed by the first general-use standard in 2000. The last major update to the standard was introduced this year with ISO/IEC 18004:2024, while Micro QR codes, which use a smaller format with less information, were last updated in 2022 with ISO/IEC 23941:2022.

There are 6 formats with most labels using Model 2. This type of bar code supports alphanumeric encoded labels in sizes large enough to hold 4,296 characters. However, encoding this much data requires a large label. The standard 33×33 module code only holds 50 characters. Labels that follow the Micro QR standard hold up to 33 characters in a 17×17 module space.

Elements of a QR Code?

QR codes contain several components to ensure scannability:

Quiet Zone

This white border isolates the code from surrounding text or images, ensuring smooth scanning.

Finder Patterns

Large squares in each corner establish orientation for scanners.

Timing Pattern and Error Correction

Reed-Solomon error correction is used to check for errors in the print caused by warping or damage. This correction code uses a standard layout spread across the entire label, increasing the chance that a damaged label will be read correctly.

Choosing the Right Error Correction for Your Codes

QR code labels support four levels of error correction:

– L: 7%

– M: 15%

– Q: 25%

– H: 30%

Q and H corrections are recommended for labels that can get dirty or be damaged during handling, such as in industrial and warehouse settings.

For consumer marketing purposes, L and M corrections are usually enough to keep the label readable. Some code designs intentionally corrupt the code by adding graphics, like a small company logo.

H correction is recommended for these codes to ensure the data remains intact. Increasing error protection also increases the size of the code. If space is limited, choose L or M encoding with no graphics. The flatter the surface, the easier it is for the scanner to read the code.

FAQs: Getting Started with QR Code Label Printing

If you’re ready to create your own QR code labels, here are a few basics to consider:

Static vs. Dynamic Codes

A static QR code holds fixed data, making it ideal for permanent info like a UPC or product part number. A dynamic QR code stores a URL, enabling flexible updates. These types of smart labels allow businesses to change the destination without reprinting labels. They’re perfect for linking to current promotions or social media profiles.

Sizing Your QR Code Labels for Optimal Readability

Like barcode labels, the right size is essential to ensuring QR codes are easy to scan. The general rule is that a QR code should be one-tenth the distance between it and the scanner. For most handheld products, a 1.2-inch code works well, while a minimum of 0.8 inches is readable by most smartphone cameras. Labels meant for shelves or walls typically require at least 2 inches in size.

When designing printable QR code labels, aim for high contrast, usually black on white, and a print resolution of 300 DPI or higher. Matte and vinyl materials are great options for longevity and readability, while label sheets work well for blank labels that can be customized as needed.

Best Materials and Templates for QR Code Labels

Selecting the right materials and printers can make a huge difference in QR code label quality. Vinyl labels are durable, and matte finishes prevent glare, improving scannability. Many businesses prefer thermal transfer or inkjet printers for high-quality, fast label printing.

When printing custom QR code stickers or larger volumes, templates can be helpful for efficient label creation, especially if you plan to customize the label designs for multiple products. Thermal transfer printing offers lasting durability, while direct thermal printing is ideal for short-term uses like shipping or address labels.

Best QR Label Printer

Print-and-apply labelers use a print engine to add information to labels. This high-speed industrial printer only supports solid black prints, but it can print fast enough that it won’t slow down labeling.

Our customizable machines are equipped with print engines from leading brands, including Zebra and Sato. Each print engine has limits for label sizes and speed, which is why we work so closely with to build a product that meets your individual needs, but they all support the 300 dpi print quality needed for clear QR code labels.

These printers also support both thermal transfer labeling and direct thermal.

Thermal transfer melts ink from a ribbon onto the label, creating a permanent print. Thermal transfer heats thermal paper labels, creating a print that fades over time.

Direct thermal prints are mostly used for short-term labels, like those used for shipping.
