One logic is that ColorMunki marketing is now pushing low patch profiling.
But unless the device is natively smooth, a low patch profile does not produce
smoothness, and may well reduce it. While newer printers are often more linear
than older models, the addition of a second set of color primaries in many
models further increases the difficulty of getting smooth native color in all
directions. Enough patches to sample each zone's gradients in detail, and correct
for nonlinearities is the only solution for increasing device smoothness. The
model of "fewer patches is smoother, more patches is more accurate" would
only work with natively smooth devices; CRT monitors come to mind with that
description, not inkjet printers.
