TIJ Printing for Pharmaceutical Packaging: Smart Coding Solutions for Serialization, Batch Numbers and Expiry Dates

Pharmaceutical packaging requires accurate, reliable, and traceable printing solutions to ensure product identification and regulatory compliance.

From folding cartons and laminated cartons to labels, small packs, and instruction leaflet bags, pharmaceutical companies need to print variable information such as GS1 DataMatrix codes, serial numbers, batch numbers, manufacturing dates, and expiry dates.

Thermal Inkjet (TIJ) printing technology has become an efficient solution for pharmaceutical secondary packaging applications. With high-resolution printing, cartridge-based maintenance, touchscreen operation, and flexible data management, Tij Printers help manufacturers achieve clear coding while reducing maintenance complexity and improving production flexibility.

What Is Pharmaceutical Secondary Packaging Printing?

In pharmaceutical production, secondary packaging refers to the external packaging that protects and organizes primary drug containers, such as cartons, boxes, and labels. Unlike primary packaging, secondary packaging often requires frequent changes in printed information due to different products, batches, and markets.

Common pharmaceutical secondary packaging applications include:

The printed information usually includes:

• GS1 DataMatrix serialization codes
• QR codes
• Lot or batch numbers
• Expiry dates (EXP)
• Serial numbers
• Product identification information

Why TIJ Printing Is Ideal for Pharmaceutical Secondary Packaging

1. 600 DPI High-Resolution Printing for Serialization Codes

Pharmaceutical companies rely on accurate and readable codes for product tracking. TIJ printers provide up to 600 DPI high-resolution printing, allowing manufacturers to print:

• GS1 DataMatrix codes
• Serial numbers
• Small text
• Variable product information

The high print quality ensures sharp edges and better barcode readability, helping scanners accurately capture data throughout the supply chain.

For pharmaceutical packaging, where even small printing errors can affect traceability, high-resolution TIJ printing provides a reliable coding solution.

2. Cartridge-Based System for Low-Maintenance Operation

Traditional industrial printing systems may require regular cleaning, ink circulation maintenance, and solvent management. These processes can increase downtime and operational costs.

TIJ printers use replaceable ink cartridges, providing a simpler maintenance process:

• Quick cartridge replacement
• Cleaner operation
• Less daily maintenance
• Reduced production interruption

Fast-drying ink cartridges are also available for different packaging materials, including coated folding cartons and laminated surfaces, helping achieve clear and durable printing results.

3. Touchscreen Operation and Easy Content Editing

Modern pharmaceutical production requires flexibility because different products may need different batch information, codes, or labeling content.

TIJ printers equipped with touchscreen interfaces allow operators to:

• Create and edit printing content directly
• Adjust printing parameters easily
• Preview messages before printing
• Manage files through an intuitive interface

With direct editing capability, manufacturers can quickly update information for different pharmaceutical products without relying on complicated external systems.

4. Flexible File Transfer and Data Management

Pharmaceutical manufacturers often manage large amounts of variable printing data. Flexible file transfer options make production management more efficient.

Depending on the printer model, TIJ systems can support:

Supported file formats may include:

Image files:

• BMP
• JPG
• PNG

Data files:

• CSV
• XLS

These functions are especially useful for pharmaceutical manufacturers handling multiple SKUs, frequent product changes, and customized packaging requirements.

5. Multi-Language System for Global Pharmaceutical Production

Pharmaceutical manufacturing is a global industry. Equipment used in different regions needs to support operators with different language backgrounds.

Advanced TIJ printers can support more than 30 system languages, providing:

• Easier operation for international teams
• Better user experience for overseas customers
• Improved adaptability for global production environments

TIJ Printing Solutions for Different Pharmaceutical Packaging Lines

Handheld Inkjet Printer

Handheld TIJ printers are suitable for flexible and small-batch pharmaceutical packaging applications.

Typical applications include:

• Manual carton coding
• Small production batches
• Product sample printing
• Multiple SKU production

For automated production environments, handheld TIJ printers can also connect with photocell sensors and integrate with conveyor systems for inline printing.

Industrial TIJ Inkjet Printer

Industrial TIJ printers are designed for continuous production lines requiring stable and efficient coding.

Applications include:

• High-volume pharmaceutical packaging
• Automated carton lines
• Multi-position printing requirements

Industrial solutions can support:

• Single printhead configurations
• Multiple printhead combinations
• Customized production line integration

This flexibility allows manufacturers to select a printing system based on their production speed, packaging design, and coding requirements.

Advantages and Limitations of TIJ Printing for Pharmaceutical Packaging

Advantages of TIJ Printing

Limitations of TIJ Printing

Although TIJ technology provides many advantages, manufacturers should also consider several factors.

Ink Compatibility

Different pharmaceutical packaging materials require different ink solutions.

For example, coated cartons and laminated packaging may require inks with better adhesion and fast-drying performance.

Extremely High-Speed Production

For very high-speed pharmaceutical lines, customized industrial configurations with multiple printheads may be required to achieve the required printing speed.

Production Environment

Temperature, humidity, and packaging surface conditions can affect ink drying and adhesion performance. Selecting the right ink and printing configuration is important for stable results.
