Colours can vary between screens, printers, paper stocks and separate production runs. Understanding these differences and preparing artwork correctly will help you achieve a more consistent printed result.
CMYK Colour Printing
Most full-colour printing uses CMYK: cyan, magenta, yellow and black. These four inks or toners are combined in different proportions to reproduce a wide range of colours.
CMYK has a smaller colour range than RGB, which is used by screens. Bright or highly saturated colours displayed on a monitor may therefore appear different or less vivid when printed.
What Can Affect Printed Colour?
Several factors can influence the final result:
- Printing process: Different presses and production methods can reproduce colour differently.
- Paper or material: Coated, uncoated, recycled and coloured stocks absorb and reflect ink differently. The same artwork may therefore look different across materials.
- Screen settings: Brightness, display settings and monitor calibration affect how colours appear on screen.
- Artwork colour mode: Artwork supplied in RGB will need to be converted to CMYK, which may change some colours.
- Separate print runs: Minor variations can occur between repeat orders because of changes in materials, ink, toner, equipment and production conditions.
- Finishing: Lamination and other finishes can affect the appearance and depth of printed colours.
Preparing Your Artwork For the most predictable results:
- Set artwork to CMYK colour mode.
- Use the correct colour profile where one has been provided.
- Supply images at a suitable resolution, normally 300dpi at the final printed size.
- Avoid selecting colours solely by how they appear on screen.
- Tell us if colour consistency with an existing item or previous order is important.
- Provide a physical sample where a close comparison is required.
Converting artwork to CMYK does not guarantee an exact colour match, but it allows you to review changes before supplying the final file.
Matching Specific Colours
An exact match cannot always be achieved using CMYK printing. If a particular brand colour is important, please provide the relevant Pantone reference or brand guidelines when requesting a quotation.
We will advise on the most suitable printing method, material and finish. Pantone references can improve colour communication, but the available matching options will depend on the product and production process.
Proofs and Test Prints
Where colour is critical, a printed proof or test print may be recommended before the full order is produced. This allows you to assess the colour, material and overall result more accurately than viewing artwork on screen.
Proofs and test prints may be chargeable and can add to the production time. They are intended as a practical guide; minor variation may still occur during the final print run.
Repeat Orders
We will use your previous order information where available, but an exact match between separate print runs cannot be guaranteed. Please tell us when ordering if the new print must be compared with an earlier version.
