In the early days of colour management, vendors of calibration software and devices did not always deliver on their promises of producing better colours with greater predictability. Everyone had different approaches to the emerging field, developing their own ‘secret sauce’ in the hope they could corner the market. Today, however, this is no longer the case. Colour management helps sign companies, print service providers (PSPs), photographers and advertising agencies better control the reproduction of colours from input devices, such as cameras and scanners, to output devices, such as wide-format inkjet printers.
