You sign off a brochure on screen, the blue in your logo looks exactly right, and a week later the printed job lands on your desk looking a shade flatter or slightly off. Nothing has gone wrong. Screens and printed material build colour in completely different ways, and the gap between them is a normal part of print production rather than a mistake to be fixed.
A screen makes colour with light. Paper, board and signage materials make colour with ink, toner or pigment that reflects the light around them. Those two systems cannot reproduce the same range of colours, so a brand colour will often look brighter on a phone than it does on a printed page. The job of good print production is to manage that gap, not pretend it does not exist.
Most screens build colour using red, green and blue light, a system called RGB. Add more light and the colours look brighter and more vivid. A phone or monitor is glowing at you, which is why strong blues, greens and oranges can look so sharp on screen.
Commercial printing usually works in CMYK: cyan, magenta, yellow and black ink laid onto a surface. Nothing is being emitted. The colour you see is light from the room bouncing back off the ink.
The two systems do not cover the same range of colours, known as the colour gamut. Some colours a screen can display sit outside what standard CMYK ink can reproduce, so a bright electric blue on screen can come back as a more restrained blue in print. That is usually a limit of the colour system, not a fault in the file or the press. Colour management tools such as ICC profiles help translate colour from one device to another, but translating colour is not the same as duplicating it.
Ink does not behave the same way on every stock. The paper is part of the colour.
This matters most for a brand that runs across a range of printed items: business cards, letterheads, brochures, presentation folders and signage. A colour approved on a gloss brochure will not look identical on an uncoated business card, and that is worth knowing before sign-off rather than after.
Large format work often moves beyond paper onto vinyl, synthetic poster stock, banner material, adhesive film, foamboard and corflute. Each surface has its own brightness, coating and way of taking ink. Because we print both paper and large format jobs in-house in Carlton, the same brand blue can run across a brochure, a pull-up banner and a corflute sign in the same week, and no two surfaces hand it back quite the same way.
A colour printed on white vinyl will not necessarily match the same colour on corflute, foamboard or a fabric banner. For a campaign that spans a brochure, a banner and an outdoor sign, the sensible approach is to treat brand colour as a range of acceptable results across materials, rather than a promise that every piece will look identical side by side.
| Material | How it handles colour | What to expect |
|---|---|---|
| Coated stock (gloss or matte) | Holds ink near the surface | Sharper, more saturated colour; the most vivid version of a brand colour |
| Uncoated stock | Absorbs more ink into the paper | Softer, flatter result; the same colour reads calmer |
| Recycled, textured or coloured stock | Base is not a pure bright white | Colour shifts again because of the surface it sits on |
| Vinyl, corflute, foamboard, fabric (large format) | Each surface takes ink its own way | No two substrates return the same colour identically; treat as a range |
A printed colour depends on the light falling on it, so the same piece can read differently in different places. A brochure under cool office lighting can look different from the same brochure held near a window. Outdoor signage shifts between full sun, shade and evening light.
This is normal, because printed colour relies on reflected light while a screen creates its own. It is also why two colours that match under one light can look slightly different under another, which is worth keeping in mind when a printed piece needs to sit alongside a painted wall, a fitout or another supplier's work.
A proof is useful for checking layout, spelling, image placement and the general direction of a colour. What a PDF proof viewed on screen cannot do is confirm the final printed colour, because it is being shown on a glowing monitor with its own brightness and profile.
Printed proofs are closer, but they also have limits if they come off a different device, stock or process from the final job. For colour-critical work, the most reliable step is a physical proof produced as close as possible to the final print conditions, looked at before the full run goes ahead.
Colour shift cannot be removed entirely, but it can be narrowed a long way. A few practical habits make the biggest difference:
International colour standards and ICC profiles exist to keep colour consistent across devices and print processes, but the final result still depends on the process, the material and the light it is viewed in.
The most useful thing a business can do is decide, up front, what its brand colour really is in print terms: a Pantone reference, a CMYK build, and an agreed amount of acceptable variation across paper and signage. Hand that to the printer at the start of a job, with a physical sample to match against where colour matters, and the conversation moves from “why does this look different” to “here is the reference we are printing to.” Across more than fifty years of commercial and large format work from our Carlton site, that one decision, made before artwork goes to print, heads off more colour surprises than any correction made afterwards.
