A3 UV DTF printer is a type of printing technology used for transferring images onto various surfaces, including textiles, glass, ceramics, plastics, and more, An A3 DTF UV printer follows a specific working process to transfer digital images onto various surfaces using UV-curable inks. Here’s a general overview of the working process of an A3 DTF UV printer:


Image Preparation:

Begin by creating or selecting the digital image you want to print. Ensure that the image is in the desired size and resolution.

Printing on DTF Film:

Load a special Direct to Film into the A3 DTF UV printer. This film has a coating designed to receive UV ink. The UV DTF printer uses precision nozzles to apply UV-curable ink directly onto the DTF film, reproducing the image from your digital file.

UV Ink Curing:

After printing the image on the DTF film, the ink is cured or dried instantly using UV LED lights. The UV light exposure ensures that the ink solidifies and adheres to the film.

Film Peeling:

Once the ink is cure, the DTF film with the printed image is carefully peeled away from the printer. The printed side of the film now holds the inked image.



Transfer Layer Application:

Apply a transfer adhesive or powder to the back of the DTF film, covering the entire printed image. This adhesive layer is essential for transferring the inked image from the film to the final substrate.

Printing onto Substrate:

Position the DTF pet film with the adhesive-covered image onto the target substrate like fabric, glass, ceramic, plastic. Apply heat and pressure using a heat press machine or similar equipment. The heat activates the adhesive on the DTF T-shirt pet film, causing it to bond with the substrate.

Cooling and Peeling:

After applying heat and pressure for the appropriate amount of time, allow the printed substrate to cool down. Once cooled, carefully peel the DTF film away from the substrate. The inked image should remain on the substrate, resulting in a high-quality, full-color print.

Final Product Inspection:

Inspect the transferred image for quality and adherence. If necessary, additional steps or adjustments can made to ensure a satisfactory result.


It’s important to note that the exact process may vary slightly depending on the specific A3 DTF UV printer model and manufacturer. Additionally, the type of substrate being used and the recommended settings can also influence the process. Always refer to the printer’s user manual and follow the manufacturer’s guidelines for optimal results.If you want a professional A3 uv dtf printer contact SUBLICOOL!
