What gets erased vs. printed

Every pixel is scored by how much ink it needs to reproduce its color on the chosen shirt — 0% for pixels matching the shirt, 100% for colors the fabric can’t help with. The two sliders below carve that scale into three zones:

no ink neededfull ink needed

Erase when ink needed is under …

Left edge of the dots zone. Raise for more breathable bare fabric.

Solid ink when needed is over …

Right edge of the dots zone. Lower for more solid ink.

In-between bias

← more inkmore holes →

Leans the in-between dot areas toward solid ink or toward breathable holes.

Drop specks below …

Ink coverage below this won’t survive the press and would flake — it’s erased instead.

Compensate remaining ink color

Where holes let the shirt show through, the surviving ink is pushed the opposite way, so from a distance the blend matches your original color (as far as printable colors allow).
