Out it goes!

Knock out garment colour: DTF knockout for black and every colour

Knockout leaves areas unprinted where the design matches the garment colour. On black T-shirts, this removes black from the print so the fabric shows through, making the print lighter and softer. Halftone 42 knocks out any garment colour, with an optional soft transition to halftone dots.

Black knockout, colour knockout, white knockout

They all mean the same thing: a colour in the design is left unprinted. Halftone 42 does this with any colour – black, white, navy or your own. Knock out more colours with the eyedropper. “Also remove matching colour inside” includes enclosed areas; “Remove background” removes a solid-colour background.

Professional settings from guides

Many guides use levels such as 10 / 1.35 / 40 for any garment colour, or 8 / 1.0 / 45 for black and white T-shirts. Enter these numbers directly under Colour → Knockout → Comparison “Levels”. Find ready-made “Pro …” presets in the “Tried and Tested” group.
