| 1 | Acrylic Material | Choose cast acrylic when optical clarity, precise cutting, and polished edges are important. Choose extruded acrylic when consistent thickness and lower material cost are priorities. | Cast and extruded acrylic are both lightweight and weather-resistant, but they differ in fabrication performance, thickness tolerance, and cost. | Ask for the acrylic type, light-transmission information, surface finish, and a material sample before ordering. |
| 2 | Acrylic Color and Finish | Use clear or translucent acrylic for light transmission. Use opaque acrylic or an acrylic face with a separate diffuser when you need stronger contrast and reduced LED hot spots. | The face material controls brightness, color appearance, diffusion, and daytime readability. | Check the sign in both daylight and darkness. Confirm whether the surface is glossy, matte, frosted, transparent, translucent, or opaque. |
| 3 | Overall Sign Size | Measure the available wall or mounting area first. Include the frame, mounting brackets, cable exit, ventilation space, and clearance from doors or walkways. | A sign that is too small may be difficult to read, while an oversized sign can create installation, structural, and permitting problems. | Record the maximum width, height, depth, mounting height, viewing distance, and required setback before requesting a quotation. |
| 4 | Letter and Graphic Scale | For early planning, a common readability guideline is approximately 25 mm of letter height for every 3 m of viewing distance, then verify the result with an actual-size or digital mock-up. | Font style, stroke width, contrast, lighting conditions, and viewing angle can change readability significantly. | Test the longest word, smallest character, logo details, and viewing distance from the main approach direction. |
| 5 | Shape and Edge Design | Rectangular panels are efficient for text. Custom-cut circles, logos, rounded corners, and freeform outlines can improve visual identity but may require more precise fabrication. | The outline affects material usage, internal LED layout, mounting complexity, and the final visual balance. | Confirm the finished outline, corner radius, minimum internal angles, edge polishing, mounting points, and cable-routing position. |
| 6 | Acrylic Thickness | For many small indoor panels, 3–5 mm acrylic may be suitable. Larger, freestanding, or outdoor signs commonly require 5–10 mm or a reinforced frame, depending on size and wind exposure. | Greater thickness can improve rigidity and impact resistance, but it also increases weight, cost, and edge depth. | Have the fabricator confirm deflection, support spacing, wind load, fixing method, and whether a metal or acrylic frame is needed. |
| 7 | Lighting Method | Use edge-lit acrylic for slim, clean-looking graphics and shallow signs. Use face-lit or internally illuminated construction when higher brightness and more even illumination are required. | The LED position, diffuser, cavity depth, and spacing determine brightness uniformity and visible hot spots. | Request a lit sample or illumination layout and check for dark corners, bright dots, shadows, and uneven gradients. |
| 8 | LED Color and Brightness | Warm white is commonly around 2700–3500 K, neutral white around 3500–4500 K, and cool white around 5000–6500 K. Select brightness for the ambient light and viewing distance rather than maximum output alone. | Color temperature changes the appearance of the acrylic and printed graphics, while excessive brightness can cause glare and poor nighttime visibility. | Specify color temperature, dimming capability, nighttime brightness, color consistency, and whether automatic photocell control is required. |
| 9 | Power and Electrical Safety | 12 V and 24 V LED systems are common. Select a power supply with at least approximately 20% spare capacity and use the correct wire size, connectors, fusing, and ventilation. | Correct power planning reduces voltage drop, overheating, flicker, premature LED failure, and maintenance problems. | Obtain the total wattage, operating voltage, estimated current, power-supply rating, cable length, control method, and electrical compliance information. |
| 10 | Outdoor Protection and Maintenance | For outdoor use, specify sealed construction, UV-resistant materials, weather-protected cable entries, and appropriately rated LED modules and power supplies. IP65 is commonly used for dust-tight, water-jet-resistant enclosures, but the exact rating must match the installation. | Sunlight, rain, condensation, temperature changes, dirt, and impact can affect acrylic appearance, electrical safety, and service life. | Confirm the intended environment, UV protection, drainage, cleaning method, access for repairs, warranty terms, local permits, and installation requirements. |
