Everything you need to know about fluorescent stickers & why to use them

Before we start, it’s worth saying that fluorescent stickers can also be referred to as neon or day-glow stickers. If you see these terms around, they can be used interchangeably.

Some industries, such as the motorsport industry use fluorescent to their advantage.

What makes fluorescent colours so bright?

Normal colours reflect a maximum of 90% of the available light as their colour. However fluorescent colours can reflect up to 300% of their colour, making them appear so much brighter.

Why?

Fluorescent colours use special pigments in their inks to absorb light outside of the visible spectrum and reemit them as light that the human eye can see.

This is what makes fluorescent colours appear brighter than conventional colours.

Here’s some technical details

Skip this if you don’t really care why fluorescent colours are so much brighter.

If you do care, this will be interesting to you…

Humans can see a very narrow range in the middle of the electromagnetic spectrum, known as the visible light spectrum.

This image helps to show how little the human eye can see in the whole spectrum:

Visible light spectrum

Normal colours absorb and re-emit a portion (up to 90%) of this visible spectrum that matches its primary wavelength (i.e. It’s colour), whilst the remaining light is absorbed and dissipated as heat.

Fluorescent colours contain fluorophore molecules that fluoresce when excited by light.

These colours use a larger amount of both the visible light spectrum and the lower light wavelengths compared to conventional colours (up to 300% more). They reemit this wider band of light as visible light to the human eye.

Because of this, the human eye views fluorescent colours as far brighter, as if they’re glowing!

When to use fluorescent stickers?

As you know these stickers are brighter & stand out way more than others.

They’re also quite unique as most brands don’t use these awesome shades of colour to their advantage.

We recommend using fluorescent stickers in some of these applications, particularly where you need to stand out, such as on a shelf when surrounded by competitors products:

  • Drinks beverage stickers
  • Food packaging labels
  • Warning stickers
  • Premium logo and branding stickers for event handouts
  • Health & Safety stickers
  • Phone and laptop branding
  • Machine labelling
  • Special promotion stickers

Here are some good examples to get your creative juices flowing:

When not to use fluorescent stickers?

Fluorescent materials are designed to be used up to 6 months outdoors and 2 years indoors.

This reduced outdoor life is due to fading (technically called photobleaching) that can occur.

The fluorescent pigments that give the colour their insane brightness also will become ineffective over time when exposed to direct sunlight.

Therefore we recommend using fluorescent stickers for mostly indoor use. For example food & drinks packaging, or for short-term outdoor use. For example; special promotion labels or construction site warning stickers.

What shades of fluorescent are available?

Fluorescent stickers are generally only available in the following shades:

  • Red
  • Orange
  • Yellow
  • Pink
  • Green

More can be created however to do this the fluorescent pigment needs to be mixed with conventional colours.

This causes there to be less fluorescent pigment in the final colour, so it will appear less bright.

This is why we recommend sticking with these shades. By combining them with other colours you can create a massive variety of different effects & designs.
