Thermal inkjet (TIJ) printing is one of the most important coding and marking technologies in manufacturing and packaging. (Other technologies include continuous inkjet (CIJ), laser marking, and thermal transfer). Thermal Inkjet printers are widely recognized for their precision, speed, and versatility. These printers have found applications across diverse industries due to their ability to produce high-quality prints on various porous and non-porous surfaces. This article delves into how TIJ printers work, what they can print, their compatible materials, benefits, and the industries where they excel.
Thermal Inkjet printing is a non-contact printing technology that uses heat to eject ink droplets onto a surface. The process involves four key steps:
1. Ink Heating: Inside the printer’s cartridge, a tiny resistor heats the ink to a temperature of approximately 300°C in a fraction of a second.
2. Bubble Formation: The intense heat causes the ink to vaporize, forming a bubble.
3. Droplet Ejection: As the bubble expands, it pushes the ink out through a nozzle, creating a droplet.
4. Bubble Collapse: When the bubble collapses, it creates a vacuum that pulls more ink into the chamber, preparing for the next droplet.
This precise process allows TIJ printers to deliver high-resolution prints, often exceeding 600 dpi, making them ideal for applications requiring fine detail. For example, our Meenjet MXPlus and MXPro series TIJ printers provide a maximum 1200 dpi high-resolution print.
TIJ printers are versatile and can print a wide range of content, including:
- Text: Such as serial numbers, batch codes, and product descriptions.
- Barcodes: Linear and 2D barcodes for inventory and tracking.
- Logos and Graphics: Company logos and intricate designs for brand identification and protection.
- Dates and Times: Manufacturing and expiration dates and times.
- QR Codes and DM Codes: For marketing, traceability, quality control, or product authentication.
The flexibility in content makes TIJ printers suitable for various labeling and coding requirements. Meenjet thermal inkjet printers, both handheld, desktop and inline models, support printing multiple content types and in different formats.
Thermal Inkjet printers can print on a broad spectrum of materials, including:
Porous substrates: such as paper (e.g. labels, packaging, documents), cardboard (e.g. boxes and cartons), foam (e.g. polyethylene foam), untreated woods, etc.
Semi-porous substrates: including waxed surfaces, plaster, concrete, coated paper, etc.
Non-porous substrates: including plastics, metals, glass, varnished woods, etc.
Here's a picture of TIJ printing on platic bottle, foam, aluminum can, carton, steel elbow, and coated metal cap.
The compatibility with diverse substrates is achieved through specialized inks, including water-based, solvent-based, and UV-curable options. Water-based inks are enough for most porous surfaces, while solvent-based fast-drying inks and special-purpose UV-curable inks are designed for non-porous surfaces.

TIJ printers offer numerous advantages that make them a preferred choice for many businesses:
High Print Quality: TIJ printers deliver sharp, legible, and high-resolution prints.
Ease of Use: Simple setup and operation make them user-friendly.
Compact Design: Their small size allows integration into tight spaces or production lines.
Low Maintenance: With minimal moving parts, TIJ printers require less maintenance compared to other printing technologies.
Cost-Effective: Affordable initial investment and low operational costs.
Environmentally Friendly: Many TIJ printers use water-based inks that are less harmful to the environment.
Speed: Capable of printing at high speeds without compromising quality.
Thermal Inkjet printers are ideal for industries and applications where precision, speed, and versatility are critical. Consider TIJ printers in the following scenarios:
Food and Beverage Industry: For printing expiration dates, batch codes, and barcodes on packaging.
Pharmaceuticals: For labeling medicines with lot numbers and regulatory information.
Consumer Goods: For branding and product identification on packaging.
Logistics and Warehousing: For marking boxes and cartons with shipping details and barcodes.
Electronics: For coding components with serial numbers and technical specifications.
Small Businesses: For on-demand printing of dates, barcodes, serial numbers on packaging or products.
The adaptability and reliability of TIJ printers make them suitable for a wide array of industrial and commercial applications.
Thermal Inkjet printers are a powerful tool for businesses seeking precise, high-quality, and versatile printing solutions. Their ability to handle diverse materials and content, combined with their user-friendly design and cost-effectiveness, ensures they remain a popular choice across industries. Whether you’re in manufacturing, retail, or logistics, TIJ printers can help streamline your operations and enhance your product presentation.
