viscosity can be merit or demerit it depends upon how we consider or when we consider it.
Advantages
Lube manufacturers have discovered that kinematic methods offer several advantages, including precision. Coupled with a high-precision thermostatically controlled bath and a timing device with an accuracy better than +/-0.001 second, kinematic viscometers are typically ten times more precise than other viscosity measuring devices such as dynamic rotational and differential pressure instruments.
A second advantage is intrinsic to the measurement method. Kinematic viscosity relies on gravity and the density of the fluid to provide the motivational force for movement of the liquid in the viscometer.
Disadvantages
More likely to smudge due to longer dry time.
More likely to “bleed” through the paper due to its absorption into the paper.
Generally run out of ink more quickly as more ink is flowing through the nib.
