What Is the Ideal Size for a GS1-Databar Stacked Omnidirectional Barcode?

The GS1 General Specifications define the dimensions for GS1-Databar Stacked Omnidirectional barcodes:

X-dimension (Width of the Narrowest Bar): 0.495 mm (recommended).
Height: 34.16 mm (1.346 inches) at the recommended X-dimension.
Width: Variable, based on encoded data.

Magnification Range:
Barcodes can be scaled between 0.396 mm (80% magnification) and 0.99 mm (200% magnification).

Quiet Zones:
Maintain a quiet zone of at least 10 times the X-dimension on each side (e.g., 4.95 mm for the recommended X-dimension).

This format suits compact applications, ensuring reliable scanning on small or curved surfaces.

What is the Character Limit of Your GS1-Databar Stacked Omnidirectional Barcode Generator?

Our GS1-Databar Stacked Omnidirectional barcode generator supports encoding up to 74 numeric characters.

How is the Checksum Calculated for GS1-Databar Stacked Omnidirectional Barcodes?

The GS1-Databar Stacked Omnidirectional barcode uses a checksum to verify data accuracy. This checksum is calculated using the standard GS1 algorithm as follows:

Identify the Data to be Encoded
The checksum applies to the full numeric data encoded in the barcode, excluding start and stop characters.
Assign Weights to Each Digit
Starting from the rightmost digit (excluding the check digit), assign alternating weights of 3 and 1:
- 1st digit × 3
- 2nd digit × 1
- 3rd digit × 3
- Continue this pattern for all digits.
Multiply Each Digit by Its Weight
For each digit, multiply its value by its assigned weight.
Sum the Results
Add all the products from step 3 to get the total sum.
Calculate the Check Digit
Determine the smallest number that, when added to the total sum, results in a multiple of 10:
- Check digit = (10 – (sum modulo 10)) modulo 10

Let’s look at an example to understand this better:

Let’s say the numeric data to be encoded is 1234567 (seven digits):

Assign Weights: Assign alternating weights of 3 and 1:
- 1 × 3, 2 × 1, 3 × 3, 4 × 1, 5 × 3, 6 × 1, 7 × 3
Multiplying Each Digit by Its Weight:
- 1 × 3 = 3
- 2 × 1 = 2
- 3 × 3 = 9
- 4 × 1 = 4
- 5 × 3 = 15
- 6 × 1 = 6
- 7 × 3 = 21
Sum of Products:
- 3 + 2 + 9 + 4 + 15 + 6 + 21 = 60
Calculate the Check Digit:
- The total is already a multiple of 10 (60).
- Check digit = 0

The complete barcode data becomes 12345670, where 0 is the check digit.

Where Is the GS1-Databar Stacked Omnidirectional Barcode Used?

This barcode format is suitable for small or space-constrained surfaces and is widely used in the following industries:

Retail:
Frequently applied to fresh produce and small packaged goods, these barcodes enable accurate identification at checkout and efficient inventory tracking. Their compact design ensures they fit on small labels, such as those on individual fruits or small containers.
Healthcare:
Ideal for labelling single-use medical instruments, small devices, and pharmaceutical products, the barcode encodes critical information like batch numbers, serial numbers, and expiry dates. This supports traceability and compliance with stringent industry regulations.
Logistics:
Used to label small packages and products with limited label space, this barcode ensures seamless integration into tracking systems. It enables efficient inventory control and accurate shipping details, even for items with curved or irregular surfaces.
Coupons:
Often seen on promotional coupons, the barcode stores details such as discounts, terms, and expiration dates. Its omnidirectional scanning capability ensures quick and reliable processing at points of sale, reducing customer wait times.

Troubleshooting GS1-Databar Stacked Omnidirectional Barcode Issues

To ensure reliable performance, address the following common issues:
- Print Quality:
  Poor print quality affects barcode readability. Use high-resolution printers to produce sharp, well-defined barcodes with sufficient contrast between the black bars and white background. Perform regular printer maintenance, including cleaning the printheads and replacing low-quality or worn ribbons.
- Quiet Zones:
  Quiet zones are essential for accurate scanning. These blank spaces must be at least 10 times the X-dimension of the barcode (e.g., 4.95 mm for a 0.495 mm X-dimension). Ensure no text, graphics, or other elements encroach into this area to prevent scanning errors.
- Data Formatting:
  Ensure the barcode data complies with GS1 standards, including the use of Application Identifiers (AIs) to specify data like GTINs, batch numbers, and expiration dates. A compliant barcode generator simplifies this process by automatically formatting the data correctly.
- Barcode Damage:
  Scratches, smudges, or environmental exposure can damage barcodes, reducing their scannability. Use durable label materials and protective laminates to safeguard barcodes. Replace damaged or worn labels promptly to maintain operational efficiency.
- Scanner Configuration:
  Not all scanners support GS1-Databar symbology by default. Check your scanner’s manual to confirm compatibility and enable this setting if needed. Update scanner firmware and test its ability to decode stacked omnidirectional barcodes before deployment.
- Scaling and Magnification:
  The barcode must remain within the specified magnification range of 80% to 200% (0.396 mm to 0.99 mm X-dimension). Ensure proportional adjustments to height and width during scaling to maintain compliance with GS1 specifications and ensure scanner readability.
By addressing these issues, GS1-Databar Stacked Omnidirectional barcodes can deliver reliable performance in demanding environments, ensuring accurate data capture and operational efficiency.

Which Scanners are Compatible with GS1-Databar Stacked Omnidirectional Barcodes?

Modern barcode scanners are widely compatible with GS1-Databar Stacked Omnidirectional barcodes. These include:
