A halftone turns parts of your artwork into a pattern of dots so the shirt itself shows through — less ink, a far softer feel, and fades that actually press. Here's how it works and how to get it right.
Look closely at a newspaper photo or a vintage band tee and you'll see the trick: the image is made of small solid dots. Bigger dots where the image is strong, smaller dots where it fades, no dots where it disappears. From arm's length your eye blends the dots and the space between them into smooth, continuous tone. Commercial printing has worked this way for over a century — a halftone re-expresses tone as dots that are either fully printed or not printed at all.
That binary quality is exactly what a DTF transfer needs. A transfer is a physical film: it can't lay down 40%-transparent ink. Asked to print a soft fade, it presses as patchy, fragile film. Halftoned, the same fade becomes crisp solid dots that press cleanly every time.
DTF lays a white underbase beneath every printed area, then color on top. Large solid regions mean full ink coverage — a heavy, plasticky patch that sits on the shirt rather than feeling like part of it. Screening those regions into dots lets the fabric breathe through the gaps: less ink, less underbase, better wash flexibility, and a print you can barely feel.
The dot pattern is also an aesthetic in its own right — the classic screen-print texture. Some designs use a coarse, visible halftone as the look, not just as a production technique.
Here's the insight our halftone tool is built on. When a dot pattern opens up, whatever shows through the gaps is your shirt. If the artwork color in that area is close to the shirt color, nobody can tell the difference — the shirt substitutes for ink you never had to print. If the artwork color contrasts strongly with the shirt, showing fabric through it would visibly shift the color.
So the smart halftone measures how close every color in your artwork is to your garment color. Close to the shirt: fade it into dots, or drop it out entirely — the shirt fills in. Far from the shirt: print it solid, so it keeps its punch. Everything in between gets dots sized so the blend of ink and fabric still reads as the intended color. That is our Match garment mode, and it works the same on any shirt color — black, white, grey, navy, red, or anything you pick.
Match garment is the mode described above, and the default. Because more of the artwork can lean on the shirt, it removes the most ink: the dot pattern is a bit more noticeable, and the print feels far softer. It is what halftoning for DTF is really for.
Brightness is the classic method, and the most common in the industry today: dark areas become dots and bright areas stay solid. (On a light shirt it flips, so light areas become the dots.) It never looks at your shirt color — only at how light or dark the artwork is. It usually keeps more of the image as solid ink: a more colorful result, but a heavier feel on the shirt.
Match garment for almost everything — the softest feel is the point of halftoning. Pick Brightness when you want maximum color and don't mind a heavier print, or when you're chasing the classic screen-print look.
Fades to transparent are the most common reason a design needs halftoning — glows, smoke, drop shadows, soft edges. The conversion is not an approximation; it's exact. A 50%-transparent pixel becomes dots covering 50% of that area. Your eye averages ink and shirt in exactly that proportion, so the pressed fade reads precisely as the on-screen fade — except now it's built from solid, pressable dots instead of impossible semi-transparent ink.
At the faint tail of a fade the dots shrink until they hit the physical limit of what adheres on a press, then stop cleanly — no ragged micro-specks that transfer today and wash off tomorrow.
Both tools let the shirt show through — they solve different problems. Color knockout removes exact flat colors, and it's the right call for illustrated designs with solid fills: the removed shapes get crisp vector-clean edges. Halftone is for everything with continuous tone — photographs, fades, glows, soft shadows, semi-transparent effects, and any art where colors blend into each other. If your design has a hard-edged solid background, knock it out; if it breathes and fades, halftone it. Many designs use both: the halftone tool bundles a knockout of your shirt color by default.
A halftone is built for one exact print size — the dot pitch is computed for those inches. The size locks first; changing it later just means re-running the halftone at the new size.
The one choice that drives everything: the canvas previews on that shirt, the tone engine measures every color against it, and the bundled knockout removes it. Six best-selling colors up front, twenty more plus a custom picker behind “More colors”.

The press file is generated at full resolution on our servers with the exact same math as your preview, and it becomes the file your order is produced from.
The defaults are tuned for DTF and most designs never need Advanced. When you do open it, every control has an info button with a full explainer — here's the short version of what each one does and why you'd touch it.
Dot shape — Round is the classic, press-reliable choice; Line trades dots for stripes and a bold retro effect.
Frequency (LPI) — how tightly packed the dots are. Lower = bigger, bolder dots that press reliably; 30 is the sweet spot for shirts.
Angle — the direction the dot rows run. 45° reads most natural; nudge it only if the pattern clashes with a texture in your art.
Levels — fine-tunes where dots begin, how fast they grow, and where ink goes solid. The tone-mode defaults are the tuned starting point.
Boost shadow — strengthens the very faintest dots so delicate fades don't vanish on press.
Knock out garment color — removes shirt-colored areas so the real shirt shows there. Leave it on unless those areas must physically print.
Minimum dot size — a physical floor: dots too small to adhere are dropped. Raise toward 0.75 pt if test presses show specks not transferring.
Post cleanup — sweeps away stray specks after screening. High gives the cleanest press.
De-fringe — replaces the thin halo at artwork edges with the art's true color, so dots stay clean-colored to the rim.
Up close, a 30 LPI halftone is visibly dotted — that's the texture, and at wearing distance it blends back into tone. Expect the pressed result to run slightly bolder than your screen preview: heat and pressure spread each dot a touch (printers call it dot gain), which reads as a slightly fuller midtone. And expect the softest hand precisely where the halftone did its work — big solid areas that would have pressed like plastic now move and breathe with the fabric.
If you're dialing in a look across a batch, press one test transfer first. Judge it at arm's length on the actual garment color — a halftone judged on a white table lies to you.
Solid, contrasting colors print solid and stay exact. In dotted regions the blend of ink and shirt is engineered to read as the original color — in Match garment mode, dots only open up where the shirt can stand in convincingly.
Because they're really there — a halftone is a dot pattern by design. Judge the preview zoomed out, at the size the shirt will be seen. If dots appear somewhere you want solid ink, switch tone mode or lower the white level so more of the design prints solid.
All of them — the engine measures your artwork against whatever color you pick. The biggest softness wins come when your design shares tones with the shirt (dark art on black, light art on white), because that's where the shirt can replace the most ink.
Yes — photos are the classic halftone subject. Continuous skin tones, skies, and shadows convert beautifully into dot patterns. Use Match garment on a shirt that shares tones with the photo's darks (or lights) for the softest result.
Pricing is based on the print's contour area, so converting solid regions to dots doesn't change the price by itself. If the bundled knockout removes a solid background, the trimmed print area — and the price — can come down.
The dot pattern is built for one exact size, so changing dimensions makes it stale. The studio flags it and offers a one-click re-run at the new size — your settings are remembered.
Properly pressed, halftone dots are as durable as solid areas — each dot is full-strength ink with full underbase. The minimum-dot-size control exists to drop the only risky dots: ones physically too small to bond.
Open the Halftone tool on any artwork — pick your shirt, pick your mode, and compare before and after live on the garment color you'll actually press.
