TIJ Thermal Inkjet Technology: A Complete Guide to Application Scenarios

What is TIJ thermal inkjet technology? Simply put, it is a marking technology that uses a heated printhead to precisely jet ink droplets onto the surface of various substrates. For an in-depth look at the operating principles and ink cartridge structure, please refer to "What Is TIJ Thermal Inkjet Printing? A Complete Beginner's Guide".

Regulatory Trends: Why Inkjet Marking Has Become an Industry Standard

Inkjet marking is no longer simply a "convenient management" option — it is a hard regulatory requirement. The EU Packaging and Packaging Waste Regulation, which took effect in 2025, explicitly requires packaging to carry a QR code or other standardized digital data carrier for traceability and recycling disclosure. This means virtually all packaging sold into the EU must bear a machine-readable inkjet mark.

Grand View Research also reports that TIJ thermal inkjet is the fastest-growing technology segment in the inkjet coding and marking equipment market, driven primarily by increasingly stringent labeling and traceability regulations across the food, pharmaceutical, and electronics industries. For inkjet coding and marking equipment manufacturers and brand owners, the supply stability and specification compatibility of TIJ ink cartridges will directly determine whether their products can meet export market compliance requirements.

Food & Beverage: Paper Packaging, Foil Packaging, and Aluminum Can Marking

The food industry demands fast drying, non-contaminating, and food-contact-safe marking. For paper packaging such as cartons and folding boxes, ink must penetrate porous surfaces quickly and dry before adjacent packages are soiled on high-speed production lines. Date codes on Tetra Pak and foil packaging must adhere firmly without smearing during refrigeration or transportation; and batch number printing on beverage aluminum cans presents similar challenges with curved and metallic surfaces.

Research published in Food Packaging and Shelf Life notes that inkjet printing on food packaging is increasingly extending into sensing and information marking applications, raising the bar for ink stability and printability. Food-grade water-based dye or solvent-based ink cartridges are recommended to achieve both vivid color and fast-drying performance.

Packaging & Logistics: Carton Batch Numbers, Barcodes, and QR Codes

The most common requirements in packaging and logistics are batch number, barcode, and QR code printing on outer cartons for warehouse traceability management. Corrugated cardboard is a porous substrate, making it well-suited to both water-based dye and pigment ink cartridges, which absorb quickly and dry fast.

Research in the MDPI Journal of Imaging confirms that print resolution and module size are critical factors in QR code readability — reinforcing the importance of 600 DPI resolution in industrial inkjet printing. Insufficient resolution leads to scan failures that disrupt shipping operations.

Medical & Pharmaceutical: Blister Foil Marking

Medical and pharmaceutical packaging carries the most stringent marking requirements. Batch codes on drug blister packs (Blister Foil) must remain legible and resistant to fading. MDPI research highlights that substrate characterization of pharmaceutical blister packaging is essential to quality assessment. Since blister materials are typically aluminum-plastic composites, solvent-based ink cartridges with strong adhesion are recommended to ensure marks remain clear after long-term storage and comply with traceability regulations.

Metal Parts Manufacturing: Serial Number Coding

Metal parts are non-porous substrates that require solvent-based ink cartridges to form a stable bond on the surface. Serial number coding is used for production traceability. Given the demanding conditions of manufacturing environments, ink cartridges with a long decap time design effectively reduce printhead clogging and maintain consistent print quality during continuous operation.

Electronic Components: PCB Batch Numbers and Part Serial Numbers

Electronics production lines demand exceptional marking precision. PCB batch numbers, component serial numbers, and anti-counterfeiting marks must remain clearly legible within confined areas. TIJ technology maintains small-character readability even at 600 DPI resolution, and paired with solvent-based ink cartridges, it delivers both scratch resistance and low odor — important considerations for indoor production environments.

Other Common Application Scenarios

Beyond the primary segments above, TIJ thermal inkjet printing is also widely used across the following industries:

Glass & Ceramic Containers

Batch numbers and expiration dates on bottles and jars. These are typically non-porous substrates, making solvent-based ink the appropriate choice.

Textiles & Non-Woven Fabrics

Label printing and non-woven bag marking. These are porous substrates compatible with both water-based and solvent-based inks.

Wood & Building Materials

Panel specifications and batch number marking. Porous substrates work well with water-based pigment or solvent-based inks, balancing scratch resistance and low odor.

Chemical & Household Product Containers

Batch numbers and expiration dates on cleaner and cosmetic bottles. Ink selection should be based on the adhesion characteristics of the specific bottle substrate.

Automotive Parts

Part serial numbers and anti-counterfeiting traceability marks, commonly applied to metal and plastic composite surfaces.

Agricultural Packaging

Batch numbers and expiration dates on seed bags and pesticide packaging. Marks must maintain weather resistance in outdoor and humid conditions; solvent-based inks are recommended.

New Energy Products

Serial number traceability marking on solar panels and lithium battery packaging — critical for product safety recalls and quality control.

Ticket Printing

Anti-counterfeiting serial number printing on high-security documents such as tickets. Invisible inks can be added to enhance the level of security.
