Abstract
A method of making a colorimeter colour standard, including determining print parameters required to achieve a desired colour for the colour standard, printing the desired colour on a colour-receiving face of a first transparent piece using the determined print parameters and permanently affixing the printed first piece to a second transparent piece such that the colour-receiving face of the first transparent piece and a joining face of the second transparent piece are positioned at the interface between the first transparent piece and the second transparent piece.
