A method transforms color values of a first device-dependent color space into the color values of a second device-dependent color space so that the visual impression of the color represented in the two-color spaces is essentially identical. The transformation of the color values combines at least one absolute rendering intent and at least one relative rendering intent.

Method of transforming a first color space into a second color space using an intermediate color space, a printing machine for implementing the method and a memory medium containing code for performing the method

A method performs color control in a printing operation on a printing machine by use of a computer. The computer uses an input profile to transform print image data from a first color space to a device-independent color space, subsequently uses an output profile to transform the print image data into a second color space dependent on the printing machine. The computer compares measurement conditions of the used input profile and of the output profile to be generated, and, if there are differences between the respective measurement conditions, adapts the print image data in the device-independent color space to deviating measurement conditions of the output profile. The printing machine subsequently executes the printing operation using the print image data, and wherein UV light excitation is used for the measurement conditions of the output profile.
