Use a backing to tie letters together
A halo backing — an outline that hugs the letters — connects separate glyphs (and floating dots on letters like i and j) into one solid body. It prints more reliably, looks intentional, and gives you 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. Pick your printer from the bed presets and watch the fit indicator — if it turns red, shrink the size or split the name across two lines. A slightly smaller sign that fits beats a big one that does not.
A tiny bevel or chamfer on the top edge of the letters catches the light and hides small layer imperfections — a cheap way to make a print look more finished.
