Product Overview
Crystal Reflective Banner is a composite media designed for large-format digital printing, combining a durable scrim-reinforced vinyl base with a layer of microprismatic reflective crystals. This construction produces a material that appears as a standard white banner in daylight but reveals a bright, reflective image when headlights or other light sources strike it at night.
This innovative material opens possibilities for impactful, 24-hour advertising and safety communication. It is engineered to run reliably on wide-format eco-solvent, solvent, and latex printers. The finished graphic is a single-layer print, eliminating the need for separate reflective cut-outs or overlays, streamlining production for impactful fleet graphics, event banners, and safety signs.

Product Benefits
Crystal Reflective Banner offers unique benefits that bridge the gap between standard print media and functional safety materials.
Dual-Day/Night Impact
Delivers a vibrant full-color message by day and transforms into a reflective graphic at night, maximizing the value and visibility of advertising space.
Streamlined Production
Enables creation of reflective graphics in a single print pass without requiring separate lamination of reflective films or intricate cut-vinyl appliqué.
Large-Format Suitability
The banner construction allows for the production of very large, seamless reflective graphics that are difficult or costly with traditional reflective sheeting.
Product Features
Key features of Crystal Reflective Banner material focus on its printability, handling, and unique visual properties.
- Integrated Reflective Layer: Microprismatic crystals are embedded within the media structure, protected by the print coating and PVC layers.
- Inkjet-Receptive Coating: A specialized coating ensures sharp dot definition, vibrant colors, and fast ink drying for roll-to-roll printing.
- Scrim Reinforcement: A polyester mesh scrim between PVC layers provides high tensile strength and prevents edge tearing, ideal for tensioned installations.
- Grommet Compatible: Can be grommeted for secure installation on fences, frames, and buildings without delaminating.
- Directional Reflectivity: The crystal layer reflects light back toward its source (e.g., car headlights), creating a brilliant "glow" effect for viewers approaching the graphic.
- Overlaminate Compatible: Can be laminated with clear vinyl films for enhanced scratch resistance, UV protection, and extended outdoor life.
- Flexible & Rollable: Remains flexible for easy handling, rolling for transport, and application on slightly curved surfaces.
- Easy Cleaning: The PVC surface can be wiped clean with mild soap and water to maintain daytime appearance.
Product Applications
Crystal Reflective Banner is deployed for applications requiring high-impact visual communication that remains effective both day and night, particularly in roadside or low-light environments.
Roadside & Outdoor Advertising
Creates unforgettable advertisements that capture attention from passing traffic 24 hours a day, significantly extending the reach of campaigns.
- Construction Site Hoarding: Branding and safety messages on perimeter fences that remain visible to nighttime traffic.
- Event & Concert Banners: Large-scale promotional banners for festivals, sports events, and concerts held in the evening.
- Retail Parking Lot Signs: Promotions, directional arrows, and store identification for nighttime shoppers.
- Billboard Backdrops: Used as a substrate for printed billboards located along highways for enhanced night visibility.
Fleet & Trailer Advertising
Turns trailers and stationary fleet assets into high-impact, day-and-night advertising platforms without complex vehicle wrap techniques.
- Side-of-Trailer Graphics: Full-color brand messages on truck trailers that reflect at night in traffic.
- Mobile Billboard Trucks: Primary graphic substrate for advertising on dedicated mobile billboard vehicles.
- Delivery Fleet Side Panels: Branding on box trucks and vans that enhances visibility and recognition after dark.
- Static Display Trailers:Banners for trailers used as temporary sales offices or exhibition stands at night events.
Safety & Temporary Traffic Control
Provides highly conspicuous safety messaging and guidance in low-light work zones or emergency situations.
- Work Zone Safety Banners: "Slow Down," "Men Working," and detour signs for nighttime construction.
- Event Safety & Wayfinding: Reflective directional signs, parking instructions, and hazard warnings for nighttime events.
- Emergency Response Signage: Rapidly deployable signs for accident scenes, road closures, or disaster areas.
- School Zone Night Warnings: Supplementary signs reminding drivers of school zone times in the early morning or evening.
Design & Production Tips
Design for Reflectivity
Use high-contrast designs. Large text and bold graphic elements outlined in dark colors with white or light-colored fill will maximize the night-time reflective effect.
Printer Profile & Settings
Use a media profile specifically for "reflective banner" or create one. May require higher drying temperatures or longer drying times due to the special coating.
Proofing & Testing
Always produce a physical proof and evaluate it under simulated nighttime conditions (e.g., in a dark room with a flashlight) to verify reflective performance.
Consider Overlamination
For applications expected to last more than one season, apply a clear UV-protective laminate to prevent ink fading and extend the life of the banner.
Frequently Asked Questions
Answers to common questions about designing, printing, and using Crystal Reflective Banner material.
How does the reflective effect work? Do I need special inks?
The effect comes from embedded crystals, not the ink. Standard solvent, eco-solvent, or latex inks are used. Where ink is printed, it blocks the crystals. Where the white media is left unprinted, the crystals are exposed and reflect light. No special "reflective ink" is required.
Can I print full-color photographic images?
Yes, but the reflective effect will be minimal to non-existent in areas of heavy ink coverage (dark shadows, deep colors). For best night visibility, designs should incorporate large areas of white or light colors and use dark colors for outlines and text.
Is it waterproof and suitable for long-term outdoor use?
It is water-resistant and designed for outdoor use. However, like standard PVC banners, its lifespan outdoors is typically 1-2 years without lamination, depending on climate and UV exposure. Lamination can extend this to 3+ years.
Can it be sewn or welded?
Yes, it can be heat-welded or sewn like a standard banner. Be aware that the sewing process will puncture the reflective layer, creating small non-reflective stitch holes. Welding is often preferred for a seamless reflective field.
How should I clean a printed reflective banner?
Gently clean with a soft cloth, mild detergent, and cold water. Do not use abrasive cleaners, brushes, or high-pressure washers, as they can damage the print coating and reduce reflectivity. Rinse thoroughly.
