To ensure the closest match to your desired colour for print, we recommend setting up your artwork files in CMYK colour mode.
Otherwise, if you'd like to specify your own CMYK values, you can view and download our CMYK colour chart here.
Please note, due to variations in monitors and browsers, colours may appear different in print than they do onscreen. If it is important that your colours are exact, it is highly recommended that you order a sample first.
