Use a backing to tie letters together
A halo backing is an outline that hugs the lettering. It connects separate glyphs and floating dots, such as those on i and j, into one solid body while adding a second colour for contrast.
Give the letters some height
Raising the letters 1.5–2 mm above the backing creates a crisp two-tone effect and makes them feel premium. Too little and the colours read as flat; too much and thin letters can wobble as they print.
Keep a flat back
Signs are authored face-up with a flat back at the bed, so they print without supports. Keep it that way: printing flat gives the cleanest front face and the strongest bond between letters and backing.
Check it fits the bed
Long names get wide. Turn on auto-fit to keep lettering within a maximum width, or use the exact finished-size control to scale the whole design. Pick your printer from the bed presets and check the fit indicator before exporting.
A small bevel can soften a top edge, but keep it modest and inspect the preview closely. A large bevel on narrow strokes can remove too much of the letter face.
