what is dtf printing

In this era of technology and innovation, people want to print their favourite designs, pictures, logos, and many more on different materials such as t-shirts, key chains, mugs etc. DTF, or direct-to-film printing, is a new technique! It makes everyday printing easier and better as compared to other methods.

If you want to know what is DTF printing? In short, DTF printing is a very easy process. A special printer, ink, transfer film and DTF powder are used in this process. Which altogether bring vivid, breathable, and wash-resistant prints on various fabrics.

Read till the end. We give you complete information on DTF printing, tips and the exact method for successful DTF printing. So, let’s get started!

What is DTF Printing?

DTF(direct-to-film) printing is a new digital technique for customized designs on a personalized substrate. This method prints a design on a unique PET film using DTF ink and adhesive powder. With the help of a heat press machine, this image is transferred to a substrate (fabric, metal, or plastic).

DTF printing has many advantages over sublimation and DTG printing. It has a wider application area on various substrates and requires no pre-treatment for transferring images.

Let’s break down the process of this (DTF) printing.

Materials Required for DTF Printing

Before starting, you need the following materials for DFT printing.

DTF Printer

A printer that is only used for DTF printing

DTF or Curing Powder

A DTF powder works as an adhesive and firmly sticks or binds the ink onto the surface of the substrate.

DTF or PET films

These specialized DTF transfer films keep the DTF INK and help to transfer them onto the substrate easily. The PET films are approximately 0.75mm thick and have a special ink-absorbing coating compared to ordinary transfer films.

DTF Inks

Are specially formulated water-soluble inks for DTF printing. The CMYK and white ink are used for printing. White ink is used on the background over which the colour image is printed.

Substrate

A substrate is a required item such as fabric, metal or plastic on which you want to print.

Heat Transfer Machine

is required to apply a specific amount of pressure and heat to transfer the image onto the substrate.

Curing Oven or Machine

A curing machine is required for evenly melting the DTF powder over the transfer film. Most printers come with a curing oven; you may also purchase it separately according to your needs.

How Does DTF Printing Work? A Step-by-Step Method

DTF printing is a fast printing method as compared to DTG  screen printing. It involves various steps, such as preparing the design, printing it onto film, curing the powder, and then printing it onto the substrate.

Here is a step-by-step method for achieving vibrant prints on apparel (light & dark) and other materials.

Preparing the design or artwork

first, prepare your favourite artwork using a DTF printer. Once you create a design, set its height and width according to the substrate size you want to transfer. Then print the image on a special DTF transfer film.

The DTF printing machine creates entirely a coloured print. After that, a white layer completely covered the coloured print. The main purpose of the white layer is that it helps to transfer images even of dark colour fabrics because the white ink or layer acts as a base colour over which the coloured image is printed.

Application of DTF powder

After printing, a thin layer of DTF powder is applied at the back of the transfer film.

Curing or heating the DTF powder

The DTF powder is heated in a curing oven for 2-5 minutes at 160-170 degree temperature. This temperature melts the powder and locks the image’s colour firmly.

Once the heating process is complete, allow it to cool down, or you may also use the infrared dryer to dry the powder directly and immediately.

Pre-press the fabric

Before the transfer of print, the pre-press of fabric is for 2-5 minutes inside the heat press is necessary. It removes any wrinkles or humidity from fabric and helps in uniform and even image transfer.

Heat transfer of print

Now place PET transfer film with melted powder onto the fabric. The image is transferred using a heat press machine for up to 15-20 minutes at a temperature of160-170°C.

Peel the film

Allow it to cool down, and peel it off carefully. Now, Post presses the fabric. This will enhance the print’s durability. After that, your apparel or garment is ready to pack.

Management of Troubleshooting Related Issues

During printing, you may experience issues like uneven transfer, colour bleeding and poor adhesion. Here we give some solutions to fix above said issues.

Uneven image transfer

Sometimes, you may experience uneven or blotchy image transfer on the fabric. This may occur due to uneven or excessive layers of powder. To resolve this issue, ensure you evenly spread the image on the film.

Colour bleeding

Sometimes, colour bleeding occurs. To fix this, use minimal powder and remove any moisture from the substrate.

Poor adhesion

Cause the print to peel off or crack. Increasing the temperature under the heat press machine can resolve poor adhesion.

Tips and Tricks for DTF Printing

Follow the following tips and tricks to ensure a complete and beautiful transfer of images without wasting materials and time.

PET Film Quality

Always use good quality transfer film for good results. Before transferring the image, check the physical condition of the PET film and avoid using any damaged films. In addition, to ensure full image transfer, the film must be free from moisture, dust or stretches.

Printing Setting

Properly set the printer setting, i.e. color saturation, resolution, and alignment, according to the size and type of fabric used for DTF printing.

Transfer film proper setting

The proper setting of the film is also crucial during printing. Because if you don’t place film across the printing area, this may lead to the uneven transfer of images.

Pre-pressing

Pre- pressing also play an important role during DTF printing. Pre-pressing helps reduce lines, wrinkles and moisture and provides a smooth surface for a complete image transfer from film to the fabric.

Time and temperature

Maintain uniform and proper temperature for curing the powder. In addition, maintenance of the heat press machine temperature is also important for curing the ink. Improper ink curing may lead to poor ink adhesion to the fabric.

Peeling of film and post-treatment

Do not immediately peel off the film. Give it to rest for 5-10 min and safely remove it while it is still hot. Press the fabric to enhance the durability and life span of the post-print. Post-treatment further enhances the bounding between ink and fabric.

Although DTF printing has its variables and challenges over time, with practice and experience, you can achieve better and more reliable transfer images.
