First it's important to understand the differences between CMYK, RGB and PMS colours. Our standard digital and offset printing is done in the CMYK colour format.
Tips to prevent colour differences
- Always deliver your prints in CMYK (or PMS for professional users)
- Make sure you know the CMYK colour codes of the most important colours
- Do you really want a exactly perfect colour? Order PMS printing instead of CMYK.
- Minimise the use of blue/purple colours for your prints
Reasons for colour differences
The colours you see on your screen will probably not look exactly the same when printed, as the colour mode screens use is RGB, while professional printing uses CMYK colours. So they both use a completely different range of colours.
If artwork is submitted as RGB, it will automatically be converted to CMYK in preparation for print. This is cause for slight colour change. Most common colours that are affected are blues and purples, or colours that are very 'bright' or close to being fluorescent colours.
The colour difference could also be because you are comparing prints on different types of paper. Because of the different characteristics of each type of paper, your colours will look slightly different.
Different printing methods can also cause a difference in colour. This means that when the same artwork is printed on different products, the results might look different, because of the use of different printing methods.
