Day Glo Signs

‘Fluorescent’ refers to a pigment that absorbs and reflects more light than conventional colours, resulting in brighter and more powerful shades.

As you may already know, the spectrum of colours goes from invisible infrared rays to high-energy ultraviolet rays. Unlike some animals, the colours that humans can actually see are the ones in the middle of the colour spectrum range, as in a rainbow.

All colours absorb daylight and re-emits a portion of the visible spectrum that matches its principal wavelength, and this is what you can see in your eyes. The ‘recipe’ of fluorescent colours include a larger amount of both the visible spectrum and the lower wavelengths compared to regular colours.

They create the appearance of vivid strong colour by absorbing and converting light energy and wavelengths of ultraviolet rays and colours lower in the visible spectrum. As a result, your eye sees a far more intense colour than regular, flat colour.

We provide the option of adding black to your printing allowing you to add depth and contrast to your design. A pop of black can serve to add detail, or be incorporated more fully in to the design, such as reversing black out of neon or vice versa. Have a few experiments with your design to see which combination of colours and coverage works best for you.

There are a limited number of Day glo colours – We print yellow, orange, pink and green.

Screenprint & Display can print day glo reflective stickers and signs. The day glo colours (orange, pink, green etc.) would be printed on to the white reflective material, all areas that are not covered by ink would reflect, any area with ink on would not.

Yes—When produced on outdoor-suitable materials (e.g. Correx or Foamex) with durable inks, your sign is weather-resistant to typical UK rain and wind. For longer outdoor runs, add a protective laminate and specify robust fixings (eyelets/cable ties).

Note: while the sign itself is weatherproof, fluorescent colours naturally fade faster than standard inks under strong sunlight.

• Correx (fluted): Lightweight, cost-effective, great for short-term outdoor campaigns like elections, events and site signage. Slight ribbing in the flute; best when budget and quantity matter.

• Foamex (rigid PVC sheet): Smoother print surface and more rigid feel for premium look and medium-term use, indoors or out. Ideal for retail displays, wall-mounted signs and repeat use.

No. Fluorescent signs are not reflective. Day-Glo colours look brightest in daylight but do not shine back car headlights at night. If you need night-time or 24/7 visibility, speak t our team about retro-reflective materials (e.g. engineering-grade/RA1 or high-intensity/RA2 reflective) or combine Day-Glo with reflective for external illumination for after-dark use.

No—Day-Glo (fluorescent) signs are designed for maximum daytime visibility by converting UV light into ultra-bright colour. Glow-in-the-dark (photoluminescent) signs store light and emit a glow in darkness without power. Fluorescent isn’t reflective and won’t glow at night unless lit; photoluminescent isn’t as vivid in daylight but is visible after lights go out.

Yes—We print photoluminescent (glow-in-the-dark) signs in custom sizes and shapes. Choose rigid boards (e.g. Foamex/ACM) or luminescent vinyl for flat surfaces. We can add protective laminate, drill holes/eyelets, and supply to common safety grades for wayfinding.

Not exactly. Day-Glo is a brand name often used to mean fluorescent inks/films—super-bright colours that pop in daylight by converting UV light.

Neon properly refers to illuminated glass tubes (or LED “neon-effect” signs) that glow because they’re powered. People sometimes say “neon colours” to mean bright fluorescent shades, but they’re different: fluorescent = daylight punch, neon signs = powered illumination.
