Abstract
A method of generating a device color profile for printing, with a printing device, on a translucent or transparent media. It includes: printing a profiling target on the media; measuring color values produced by the profiling target, when illuminated in transmission and when illuminated in reflection, in a device-independent color space; combining the transmission and reflection color values into combined transmission-reflection color values and creating a combined transmission-reflection profile mapping color values from a device-dependent color space to the device-independent color space; reversing the combined transmission-reflection profile, thereby obtaining the device color profile. The device color profile maps color values from a device-independent color space to a device-dependent color space in a manner which represents a color-reproduction compromise between transmission and reflection.
