The M-score came from Idealliance digital press certification.But I do not make it clear how to calculate it? Anyone know more details about it? Thanks in advance."The press sheets described above will be measured using colorimetry and the measuring geometry and configuration as stipulated in this document. The M-Score procedure is used as a pass/fail criterion for this test.
The M-Score is based on ISO 15311. The M-Score computes a single value, scaled from 0 (poor reproduction) to 100 (perfect reproduction), which correlates well with the perception of print variations for a uniform tinted test form printed on digital press systems. The following procedure is used to calculate the M-Score."

Hi Mike –
I have developed an Excel spreadsheet to calculate M score along with a visualization chart of the readings showing areas where dE00 varies the most. This was part of a total G7 Digital Press Report to calculate all the metrics of the qualification criteria.
I'd be happy to share it with you with the caveat that you may need to adjust the links slightly, depending on the CGATS measurement file header format.
