What is transfer printing, and when does DTF fit, when flex or flock? How the methods work, which garments they hold on and which file you need.

What is transfer printing?

Transfer printing is the umbrella term for all methods in which the design is first created on a carrier and only then goes onto the garment. The carrier is a film. In a transfer press, heat and pressure bond the design to the fabric, then the film is peeled off.

In screen printing, by contrast, the ink runs directly through a screen onto the garment. That pays off mainly for many identical pieces in few colours. How the two approaches differ is shown in our comparison screen printing or transfer printing.

For companies, teams and clubs, transfer printing is especially practical because no screens need to be set up. If you want to have T-shirts printed with your logo, it is usually the first choice for multicolour designs.

Two families

In digital transfer printing (DTF), the film is printed. With flex and flock, a coloured film is cut. Both are pressed on the same way at the end.

DTF: transfer printing in every colour

DTF stands for direct to film. A printer applies your design digitally to a carrier film, all colours in one pass. On dark fabrics a white base layer goes under the colours so they stay strong.

The film is then coated with an adhesive powder. In the press, the adhesive melts and bonds the design to the fabric. Because no screens are needed, the number of colours does not matter: photos, gradients and fine lines come out cleanly.

DTF adheres to cotton, polyester and blends. That makes it suitable for sports shirts, softshell jackets and bags as well. What matters for sports shirts is covered in Printing running shirts. You can find more about the method on our digital printing page.

Flex and flock: film from the plotter

With flex and flock, nothing is printed. A cutting plotter cuts letters, numbers or shapes from a coloured film. The excess parts are removed by hand, then the transfer press applies the design to the garment.

Each colour is a separate film. That makes flex and flock ideal for single-colour lettering, names and numbers in strong colours – the classic on jerseys. Very fine lines and tiny parts, on the other hand, are hard to cut. How we use flex, flock and DTF in our own workshop is shown on our page custom textile printing.

Which transfer print suits your design?

The quickest way to decide is by your design. These cases help with a first assessment:

  • Your logo has many colours or a gradient.

    DTF

  • You want to print a photo or a detailed illustration.

    DTF

  • Each jersey gets its own name and number.

    Flex or flock

  • You are printing sports shirts or softshell jackets.

    Usually DTF

  • Your design is single-colour lettering in a strong colour.

    Flex or flock

  • Often the best answer

    Combine both

    Crest and sponsor in DTF, names and numbers in flock.

    DTF + flock

Which fonts are easy to read on a jersey is shown in our post on the right jersey font.

Which garments transfer printing holds on

Transfer printing is flexible when it comes to fabric. What matters are the material, the surface and the area to be printed:

  • Cotton T-shirts

    Suitable for all three methods.

    Flex & flock DTF

  • FrontBack

    Hoodies

    Small multicolour chest logo in DTF, lettering or name on the back in flex or flock.

    Flex & flock DTF

  • Sports shirts, rain jackets, softshell

    Usually DTF – the transfer bonds well with synthetic fabrics.

    DTF

  • Bags and backpacks

    We print cotton bags with both methods; for coated fabrics we tend to use DTF.

    Flex & flock DTF

Which file you need for transfer printing

  • Ideal

    Vector: PDF, AI, EPS, SVG

    Ideal for flex and flock, because the plotter cuts along the outlines. Also the best choice for DTF.

  • Enough for DTF

    PNG, transparent, high resolution

    For DTF, a good pixel file with a transparent background is enough.

  • We check

    Photo or small graphic

    Send it anyway. In the layout consultation we tell you whether it is good enough for printing.

Give colours as values

Ideally as Pantone or HKS values. For flex and flock we choose the film colour closest to your value.

The larger the print

the more pixels the file needs. Left too few, right enough.

How long does the print last?

Side note

A long time with proper care. More important than the method are the right garment and the care instructions. We advise you on this before production.

  • Wash inside out

    That way nothing rubs directly against the print in the machine

  • Follow the care label

    Temperature and programme depend on the garment

  • Ironing directly over the print

    If needed, iron inside out or with a cloth in between

Is DTF the same as transfer printing?

DTF is today’s most common form of transfer printing. Flex and flock belong to it too: there the film is cut rather than printed.

What is the difference between flex and flock?

Both are cut from coloured film and pressed on. Flex has a smooth surface, flock a velvety, slightly raised one.

Can you feel a transfer print on the shirt?

DTF sits on the fabric as a thin, flexible layer. On large areas you feel it slightly more, on chest logos hardly at all. Flock is meant to feel velvety.

Can I combine transfer printing and screen printing?

Yes. For example the logo in screen printing and names in flock, or a multicolour design in DTF. We tell you in the consultation what makes sense.

Will I see what my design looks like before printing?

Yes. Before production you receive a print approval on which you check position, size and colours.
