From pharmaceuticals to packaged foods and consumer goods, barcodes ensure that each item is accurately tracked throughout the supply chain.
But achieving perfect barcode printing isn’t just about using the right machine. It involves a combination of choosing suitable printing technology, understanding packaging materials, maintaining quality control, and adapting to variable data needs.
Why Barcode Printing Matters
Barcodes are more than just black-and-white lines. They are machine-readable data used to track, verify, and authenticate products. A poorly printed barcode can lead to:
-
Scanning errors
-
Product returns
-
Regulatory non-compliance
-
Customer dissatisfaction
For Indian manufacturers, especially in sectors like pharma, FMCG, agriculture, e-commerce, and logistics, ensuring barcode quality is essential.
Key Elements for Perfect Barcode Printing
1. Select the Right Printing Technology
Different packaging types require different printing methods. Choosing the wrong one can lead to smudged or unreadable barcodes. Here are some widely used options:
-
CIJ (Continuous Inkjet) Printers – Ideal for fast-moving production lines and porous/non-porous surfaces. Learn more in What is CIJ Technology?
-
TIJ (Thermal Inkjet) Printers – Suitable for printing on paper, cartons, and labels with high-resolution output. Check our MRP Printing Machine Guide
-
Laser Marking Machines – Permanent, eco-friendly solution for high-volume applications. No ink required.
-
Thermal Transfer Overprinters (TTO) – Ideal for flexible packaging, especially in the food and pharma industries, offering crisp and smudge-proof codes.
2. Understand Your Packaging Surface
Perfect barcode printing also depends on how well the ink or thermal print adheres to the packaging. Common materials include:
-
Plastic pouches and shrink wraps
-
Cardboard cartons
-
Woven PP bags
-
Laminated films
-
Glass bottles
Each of these materials requires a specific ink type or printing method. CIJ ink or TIJ cartridges vary in dry time, adhesion, and resistance to smudging.
3. Ensure Quality with Inspection Systems
Using a Batch Code Inspection System helps verify barcode readability in real time. These systems use cameras and OCR technology to:
-
Check for missing or misprinted codes
-
Ensure codes are scannable
-
Prevent defective items from reaching the market

4. Manage Variable Data
Modern barcodes are no longer static. Many industries now use variable barcodes that contain batch numbers, expiry dates, QR codes, or serial numbers—critical for traceability and recall management.
QR code-based systems are increasingly used in agriculture and pharma to let end-users scan and verify product authenticity.

FAQs About Barcode Printing
Q1. What’s the difference between a barcode and a variable barcode?
A regular barcode contains static product info. A variable barcode includes dynamic data like expiry dates or serial numbers that change per item or batch.
Q2. What if a barcode isn’t scannable?
If contrast, size, or placement is off, scanners can't read the code. Using high-resolution printers and verification systems solves this.
Q3. Can I print barcodes on laminated packaging?
Yes, but it requires fast-drying, high-adhesion inks, typically found in CIJ and TTO printers.
Q4. Do all barcode printers support variable data?
Not all. Ensure your printer supports real-time data input and integration with databases.
