Recent developments in printing methods continue to expand the sphere of garment customization. One method that has gained popularity in recent years because of its versatility is DTF printing. You might have heard of it before, and here I will tell you why its use is booming.
Direct Film (DTF) involves printing your design directly to a polyester film using a specialized printer, adding adhesive powder, and then transferring the design to fabric using a heat press machine.
DTF printing quickly caught on because it allows the liberty to work on different surfaces and several fabric types while still producing vibrant and lasting prints. It works well on cotton and cotton blends, polyester, fleece, and nylon, regardless of colour.
This cutting-edge technology can be a game changer for your garment customization business or hobby. Let's explore how it works in detail
Here is a detailed step-by-step process for implementing DTF printing.
Step 1: Preparation of the Design and Printer
Once you have settled on the design, import it to the Image processing Software.
Then, calibrate the required cartridges to set up the DTF printer. Cut out the PET film and load it onto the DTF printer.
Step 2: Print the Design
Print the entire design in color. The printer creates the first layer, and then the machine prints the white layer on the whole image, completely covering the first layer. Carefully remove the Film and lay it on a flat surface.
Step 3: Adhesive Powder Application and Curing
Apply the powder uniformly on the wet ink until complete coverage. Remove the excess powder.
Cure the adhesive by heating the Film in a curing oven or with a heat press machine.
Step 4: Heat Press the Design
Pre-press the fabric using a heat press for 2-5 seconds. This process dehumidifies and flattens the garment.
Place the printed Film on the fabric, then heat press it for 15-20 seconds at temperatures of 165°C to transfer the image.
Peel the Film from the garment and flatten the design by heat pressing it a second time.
DTF Printing Equipment
Software for DTF Printer
DTF printing requires specialized Taster Image processing software (RIP) to handle CMYK and White colours. RIP converts vector designs to bitmaps optimized for printing. The software impacts the colour performance, ink print features and final print.
DTF Printer
The printing requires a specialized or modified inkjet printer with textile inks specific to DTF printing. Multiple coloured ink tanks allow the printer to work conveniently with CMYK settings.
DTF Printer Ink
The DTF printer inks are unique water-based and solvent-based pigments designed in Cyan, Yellow, Magenta, White, and Black. Water-based inks are more environmentally friendly, but solvent-based ones are more durable.
DTF Printer Films
The DTF printer uses PET films, which are different from the ones used for screen printing. The PET films are 0.75 mm thick, which gives them better transfer characteristics. They are classified according to:
Release mechanism: Cold peel type and hot peel type.
Visual effects, e.g. reflective film, laser film, luminous film, shining film, gild/silver film, glossy transfer film, and color base film.
Coating process: Single-coated and double-coated films.
Hot-Melt Adhesive Powder
DTF printing powder is a white granular powder used for adhesive purposes. It is made from a mixture of polyester and polyurethane resin, color, and other additives. The powder helps to bind the coloured pigments in the printout to the garment surface.
Curing Oven
A small industrial oven melts the hot melt powder onto the transfer film. The heat press machine can also perform this function in a no-contact mode.
Heat Press Machine
This equipment helps to transfer the images onto a fabric surface. It can also melt powder on your DTF film.
Advantages and Disadvantages of DTF Printing
Here are pros and cons of DTF printing.
Advantages
Low initial investment.
With a proper selection of good-quality ink, printer, and fabric, it produces high-resolution prints with vibrant colors and finer details.
It can work on several fabrics, such as cotton and cotton blends and other varieties like polyester, fleece, and nylon.
With good ink, DTF printing provides elastic prints that won’t crack when stretching the fabric.
It provides good wash and wear resistance, especially when good-quality ink, fabric, and curing processes are used.
It does not require any pre-treatment.
Cons of DTF Printing
DTF printing is a delicate process and requires one to use quality printers, ink, and consumable materials to eliminate deviations in the quality of the output.
