The aim of colour management is to ensure that colours are reproduced as similarly as possible across different devices such as cameras, scanners, monitors, laser, inkjet, offset printers and many more.
For colour management to work, device-dependent colour spaces such as the colour gamut of your own monitor and printer and device-independent colour spaces such as AdobeRGB 1998 or LAB must be available on a computer. With this knowledge, the computer can understand the image display on a monitor and output a true-colour image on the connected inkjet printer.
Modern colour management systems consist of measuring devices such as the X-Rite i1 Pro 2 and the corresponding colour management software, which creates and manages the colour profiles determined by measurement and makes them available to application programs such as the Adobe product range.
