It's interesting question. From my experience, there is not enough 1400 patches

problems are in the darks: the printer and paper combination may have an
unpredictable
behavior (steepness of device response in dark region) and the 1440 patches of
OFPS is
insufficient. With 1440 patches, darks are not well characterized in 50% of
cases.
There may be few patches per volume unit of the darks.
Hi Nikolay,
where in the dark gamut do you think this problem lies ?
Towards neutral, or towards the edge of the gamut ?
