Colors

Number of colors

Count the background too, unless the PNG is transparent there.

Trace resolution

The image is resized to this before tracing. Small PNGs get upscaled for smoother curves.

Cleanup

Edge smoothing

Removes jaggies and stray anti-alias pixels. Higher also drops very thin lines.

Remove specks under

Little islands this size or smaller merge into the surrounding color.

Vector

Simplify

Higher = fewer nodes and smoother curves, lower = follows the pixels more closely.

Corner angle

Turns sharper than this stay pointed; gentler ones become curves.

Trap (overlap)

Lighter inks spread under darker neighbors so press shifts don't leave gaps.

Output

Art width (inches)

Registration marks & film labels
