Heat transfer printing is an emerging printing technology. This process is divided into two main parts: transfer film printing and transfer processing. Transfer film printing utilizes dot printing (with a resolution of up to 300 dpi) to pre-print the design onto the surface of a thin film. The printed designs have rich layers, vibrant colors, and can vary greatly, with minimal color difference and good reproduction quality. This method meets the requirements of designers and is suitable for mass production.
Heat transfer printing involves transferring the design from the transfer paper to the surface of the target object using heat and pressure. It requires a heat transfer machine or a heat press to accomplish this, fixing the design onto the material's surface through high temperatures and pressure.
What are the advantages of heat transfer printing?
- High Efficiency
Can achieve high-quality, durable printing results.
- Simple Operation
No complex printing process is required, making it suitable for personalized customization and easy to produce small batches.
- Environmentally Friendly and Non-Polluting
Because it does not require the use of chemical solvents, it has a minimal environmental impact.
What Are The Disadvantages of Heat Transfer Printing?
- Higher costs due to the need for special equipment and materials.
- Limits the printing of some complex patterns or colors on the electrode patchs.
- Material restrictions, as it requires high-temperature resistance.
Process Flow
- Preparation Stage
Pre-print the designed pattern onto a special transfer film using a halftone printing method, ensuring the pattern has high resolution and good color representation.
- Transfer Stage
Bring the patterned transfer film into contact with the electrical pads and perform heat transfer at a specific temperature and pressure. The typical heating temperature is 180-200°C to ensure the ink fully sublimates and transfers to the TENS unit electrodes.
- Post-Processing Stage
After the transfer is complete, further processing of the TENS machine electrode pads can be done through oil spraying, sandblasting, secondary injection molding, etc., to enhance its performance and appearance quality.
