Inkjet Colour Management
Practical Colour Management For Digital Printing Workflows
Wednesday 12 - Thursday 13 June, 2019
Møller Centre, Cambridge, UK
Accurate reproduction of colour is an essential aspect of printing, and the need to ensure true colours can be a limiting factor in digital adoption. Central to the task of reproducing colour correctly is colour management - the process by which colour is measured, represented and output by different imaging, viewing and printing devices. The aim is to put in place a system that allows colours to be designed and output in an efficient and accurate manner. The Inkjet Colour Management course introduces the key technology and processes required for colour reproduction, presented by Gerrit Andre of leading digital printing software provider ColorGATE.
