DTF Printing 101

DTF stands for direct-to-film. It is the fastest, most forgiving way to put full-color artwork on a shirt, and it is the reason a one-person operation can now compete with a screen printing shop.

How DTF actually works

Your artwork gets printed in reverse onto a clear PET film using specialty water-based inks. While the ink is still wet, a fine adhesive powder is dusted across it and melted in a curing oven. What you get back is a finished transfer: your design, sitting on a sheet of film, ready to press whenever you want.

1. Print. CMYK plus a white underbase goes down on the film, so colors stay bright on black shirts as well as white ones.
2. Powder. Hot-melt adhesive sticks only to the wet ink.
3. Cure. The sheet goes through an oven so the powder melts into the ink layer.
4. Press. You place it on the garment, press it, and peel the film off.

Why crafters are switching to it

• No weeding. Unlike HTV, there is nothing to pick out with a hook. Complex line work and tiny text just work.
• Unlimited color. Photos, gradients, distressed textures, all in one press.
• Works on nearly everything. Cotton, polyester, blends, canvas, denim, hats, bags. Sublimation can only handle light polyester.
• No minimums. One design or two hundred, the cost per print is the same.
• Shelf stable. Transfers keep for months in a cool dry drawer, so you can print a batch now and press as orders come in.

DTF vs. the alternatives

Method	Best for	The catch
DTF	Any fabric, any color, full color art	Slight hand feel on very large prints
HTV / vinyl	Simple one-color text and shapes	Weeding is slow; layering colors is painful
Sublimation	White polyester, mugs, hard goods	Will not work on cotton or dark garments
Screen printing	Hundreds of the same design	Setup cost per color makes small runs uneconomical

Pressing settings

Every press runs a little hot or cold. If the design lifts with the film, your press was too cool or too fast. If the print looks glossy and stiff, you went too hot or too long.

Artwork requirements

• PNG with a transparent background. JPGs carry a white box we cannot remove.
• 300 DPI at final print size. A 600 pixel image blown up to 11 inches will print soft and pixelated.
• Size it before you send it. A standard adult chest print runs about 10 to 11 inches wide; a left chest or pocket print is 3.5 to 4 inches.
• Watch thin strokes. Anything under about 1 point can break up on press.

What is a gang sheet?

A gang sheet is one 22 inch wide roll of film with as many designs as you can fit packed onto it. You pay for the length of film, not the number of designs, so nesting your artwork tightly is how you drive your cost per print down. Ten small pocket logos on a single 22x12 sheet costs the same as one big design on that same sheet.

Cut them apart with scissors as you need them. This is the single biggest cost lever in DTF, and it is why we sell by sheet size rather than per design.

Caring for the finished shirt

• Wait 24 hours before the first wash.
• Turn inside out, cold water, gentle cycle.
• Tumble dry low or hang dry. High heat is what kills prints.
• No bleach, no fabric softener, never iron directly on the design.

Pressed correctly, a DTF print will outlast the shirt underneath it.
