Thermal Transfer Film Production Process

The production processes for thermal transfer films can be categorized into screen-printed thermal transfer films, gravure-printed films, and high-definition digital thermal transfer films. Screen printing Heat transfer film Rare and technologically outdated. Intaglio thermal transfer films are widely used. High-definition digital thermal transfer films offer excellent flexibility and can be produced in any quantity, though their cost is relatively high. With the widespread adoption of panel products made from various materials, consumer expectations for panel surfaces continue to rise. Thermal transfer printing is one of several methods for surface decoration of panels, offering advantages such as high production efficiency and superior decorative effects.

Comparison between intaglio thermal transfer film and high-definition digital thermal transfer film:

1) Different processes. Gravure printing is complex, while high-definition digital heat-transfer film printing is simpler. The key difference is that gravure requires a printing plate, whereas high-definition digital printing does not. Digital printing can be thought of as a printer that directly outputs the design.

2) Order flexibility differs. Gravure printing is suited for large‑volume orders, while digital high‑definition heat‑transfer film is ideal for both large and small orders.

3) Prices differ. Intaglio printing equipment is relatively inexpensive, and the cost of transfer films is much lower. For high-definition… Heat transfer film , The equipment is relatively expensive, so the cost of printed patterns is higher.

4) Production lead times differ. Gravure printing has a longer production cycle: typically 3 days for plate preparation, 4 days for pattern creation, totaling about 7 days, and up to 10 days during peak periods. In contrast, printing, designing, and delivering high‑resolution thermal transfer films takes only 3 days.

5) The textures differ. The ink layer in intaglio printing is relatively thin, around 25 µm, whereas the ink thickness on high-definition digital film is approximately 100 µm—quite a noticeable difference. When you run your fingers over the pattern on a high-definition thermal transfer film, you can feel the raised ink layer, which has an excellent tactile quality. For printing small fonts, high-definition printing delivers superior results.

6) The sanitary and environmental conditions differ. Gravure printing machines are large and occupy a substantial footprint, with significant pollution. In contrast, high-definition film printing involves compact equipment and generates far less pollution.

Heat transfer film It involves printing graphics and text onto the surface of adhesive paper or plastic film using various printing methods; when applied, it adheres to the decorated panel or other substrates, transferring the printed design onto the treated surface and thereby achieving graphic printing.

Heat-transfer films can be classified according to their transfer mechanism into pressure‑based and heat‑based methods. Heat transfer, in turn, may be categorized by ink type and further divided into heat‑press transfer and sublimation transfer. Heat‑press transfer involves applying heat and pressure to transfer graphics and text onto the substrate to be decorated.
