TTO Frequently Asked Questions

Frequently Asked Questions About Thermal Transfer Over printer

Linx Printing Technologies newly launched Thermal Transfer Overprinters (TTO) are designed to deliver high-quality, reliable coding on flexible packaging across a wide range of industries. Ideal for applications such as film, labels, pouches, and flow wrap.

Using advanced thermal transfer technology, these printers apply ink from a ribbon directly onto the substrate, ensuring durable and consistent print quality even on fast-moving production lines.

Engineered for efficiency and ease of use, the Linx TTO Series helps manufacturers minimise downtime, reduce errors, and maintain consistent coding performance across diverse packaging environments.

In this blog, we answer some of the most frequently asked questions about TTO printers to help you make informed decisions. If your question isn’t covered, get in touch with our team we’d be happy to discuss your specific challenges and recommend a solution tailored to your production needs.

How does a Thermal transfer Over printer work?

Linx Thermal Transfer Over printers use a precise heat transfer process to apply clear, durable codes directly onto flexible packaging films, making them ideal for high-speed FMCG production lines. A heated printhead transfers ink from a ribbon onto the packaging film. The TTO produces high resolution prints that are dry instantly. There are no solvents involved and no drying time needed. The TTO is suitable for both intermittent and continuous motion packaging lines and is ideal for date codes, batch numbers, prices, barcodes, QR codes, and logos.  

What materials can TTO printers print on?

TTO printers are designed for flexible packaging materials, including plastic films, foils, laminates, paper, and labels. They are ideal for applications such as flow wraps, sachets, and pouches.

What are TTO printers used for?

TTO printers are used to print variable information on packaging, including expiry dates, lot codes, barcodes, QR codes, and logos. They are commonly used in food, beverage, pharmaceutical, and FMCG industries.

Does thermal transfer require ribbon? 

Thermal Transfer Over printers require ribbons to print onto flexible packaging materials. TTO uses a range of wax ribbon, wax-resin ribbon and resin ribbon. A coating of the ribbon is melted onto the flexible packaging material and prints the desired code. Most ribbons are black and there are colour options available.

What is the different between TTO and TIJ?

Linx TJ printers use ink cartridges and print ink-based codes through a heated nozzle onto porous materials.  

TTO uses a thermal printhead and ribbon by transferring solid ink from the ribbon onto the packaging and is ideal for flexible packaging films.  

What is the difference between TTO and CIJ printers?

TTO printers are best suited for high-quality printing on flexible packaging, while Continuous Inkjet (CIJ) printers are better for non-contact coding on a wider range of surfaces, including uneven or curved products.

How long does a TTO last?

A well-maintained TTO can operate reliably for many years, sometimes over a decade. However, lifespan varies based on print volume, environment, and maintenance quality. Using genuine Linx spare parts and monitoring maintenance will prolong the lifetime of the printer. Linx have a number of servicing and support options to maintain the quality of your TTO printer.  

Things to consider when purchasing a TTO 

Thermal transfer printers are a great solution for printing barcodes, date codes, nutritional information and QR codes onto a range of flexible packaging materials.  

However, TTO can have limitations depending on the substrate and material that is being printed on. The speed of the production line is also a key factor to consider when purchasing a TTO printer.  

It’s important to check the substrate compatibility before purchasing a TTO printer. 

Our Linx product experts are on hand to assess your printing requirements and ensure you have the correct printing technology suited to your business environment. 

Are TTO printers suitable for high-speed production lines?

Yes, TTO printers are specifically designed for high-speed packaging environments. They deliver consistent, high-resolution prints without compromising production efficiency.

What do Linx offer? 

Linx offers a range of three thermal transfer overprinters suitable for different print speeds and areas.  

  • TT500 – Ideal for standard flexible packaging lines with a compact cassette for tight machine spaces. 
  • TT750 (32mm and 53mm printhead)– Larger print areas for more data or bigger messages. Suited to mid speed production lines. 
  • TT1000 (53mm and 107mm printhead) – Wider print format for graphics and multi-line information suited to higher speeds.
