3 built-in test charts are available for Monaco RGB printer profiling. The smallest test chart consists of 343 reference patches. These test charts are preassigned and its RGB reference set does not make known publicly. But one can still extract such information after the measured result is saved in Monaco session file in that the RGB data is stored in 16-bit RGB values. If the RGB reference data is altered by more than 1 count the profiler will reject the saved session data set.
The RGB reference points are equally spaced. For Monaco 343 test chart, each RGB channel was divided into 7 points from value 0 to 255, hence 7x7x7 or 343 test points.
The reference RGB, measured Lab data and the printer gamut which was derived from the measured Lab, are illustrated below.
