If the client already knows what they want, say so in the notes and it designs around that. - ### Face-lit channel letters Translucent acrylic faces lit from inside — the brightest, most legible option for a busy street or a long reading distance. - ### Halo-lit (reverse) channel letters Solid faces on standoffs, with light washing the wall behind them. A quieter look for refined brands and smooth, pale facades. - ### Open-face channel letters Open returns with exposed LEDs or a clear face, for a vintage marquee feel. Ask for it in the project notes and it is drawn and specced like the others. - ### LED neon Flexible LED neon on a clear or hidden rail, for script logos and a warm evening glow — kept legible, not novelty. ![Sea-glass halo, café shopfront by day](https://assets.aisignmockup.com/public/site/home/cafe-a-day-1600.webp) Day ![Sea-glass halo, café shopfront at dusk](https://assets.aisignmockup.com/public/site/home/cafe-a-dusk-1600.webp) Dusk **Sea-glass halo** Halo-lit reverse channel letters, 3 in. returns 11′ 6″ wide · 10 in. caps · same design by day and at dusk ### What goes into each spec Construction Letter type, faces, returns and any backer or rail, written the way a fabricator reads it. Return depth In half-inch steps — usually 2–5 in. for lit letters, ½ in. for flat cut letters. Lighting Method and colour temperature, plus how the sign reads by day and at night. Mounting How it fixes to the building: standoffs, a rail or raceway, or flush to the wall. Size Cap height and overall width in feet and inches, judged against things in the photo — or against a scale you mark on it. ## Channel letter mockups from real runs Unretouched agent output on real site photos — each one passed the agent’s own check against the photo. ![Sea-glass halo, café shopfront at dusk](https://assets.aisignmockup.com/public/site/home/cafe-a-dusk-1600.webp) **Sea-glass halo** Halo-lit reverse channel letters, 3 in. returns ![Neon wave script, café shopfront at dusk](https://assets.aisignmockup.com/public/site/home/cafe-c-dusk-1600.webp) **Neon wave script** Warm-white LED neon on a concealed rail ![Bakery shopfront at dusk with LED neon script and a projecting blade sign](https://assets.aisignmockup.com/public/site/home/bakery-neon-1600.webp) **Bakery · LED neon script + blade sign** LED neon script on a clear carrier — re-drawn once after the agent’s own review found it crowding the corbels. ## From site photo to approved sign, in three steps. About 2–3 minutes per design run. 1. **Snap the site photo** Photograph the shopfront from across the street and add the client’s logo — or just the business name and trade. Notes like “must be halo-lit” go in too. 2. **Four buildable concepts** The old sign is erased and four concepts are placed on the photo, each a different construction with its own spec. The agent checks every render against the site photo and re-draws the ones that fail; lit signs come at dusk and by day. 3. **Approval link + vector pack** Send the client a link they open without an account to compare, comment and sign. Then export the approved design as SVG, DXF and PDF — design files, not factory files. ## Questions sign shops ask Can it show how halo-lit and face-lit letters look at night? Yes. Lit concepts are rendered at dusk with the sign switched on — the halo glowing on the wall, faces lit, neon glowing — and every concept also comes in a daytime version of the same design, so the client sees both. Which type of channel letter does it choose? It decides per job, from the brand and the facade — for example halo-lit for a quiet, refined look, face-lit for reading from across the street, LED neon for a script logo. The four concepts always differ in construction. If the client has asked for something specific, such as open-face letters, write it in the project notes. Does the mockup include return depth, mounting and colour temperature? Yes. Every concept comes with a short spec: construction, return depth, lighting method and colour temperature, mounting, colours and materials, cap height and overall size in feet and inches. Sizes are estimated from the photo unless you mark a scale on it in the editor. Can I send the files to my fabricator? You can export a vector pack: a 1:1 front elevation as SVG and DXF with outlined text on separate layers, an elevation PDF with a title block, and a spec sheet PDF. They are design files, not factory files — your fabricator still makes the production drawings. How much does it cost to try? The free plan has 3 credits and needs no card. A design run of four concepts uses 2 credits and each change uses 1, so you can run one job and refine it once. Free renders carry a watermark. ## Put channel letters on your next site photo.
