What is the relationship between the fluidity and viscosity of ink?What role does
the fluidity of ink play? The relationship between fluidity and viscosity is inversely
proportional. The greater the fluidity, the lower the viscosity; The lower the fluidity,
the higher the viscosity. The fluidity of the ink is good, which can ensure the quality
of printing to a certain extent, because under the same pressure, the ink can easily
spread the ink film with uniform thickness on the surface of the ink roller, and
maintain good transfer, so that there will be no uneven depth prints during printing.
What is the relationship between the fluidity and viscosity of ink?There are many
ways to dry ink. In fact, different inks will use different methods to dry ink according to
their characteristics and printing methods. Generally speaking, there are no following
kinds: ink oxidation: this drying form of polymer conjunctiva is the main drying form
of lithography; Permeation drying: when the ink is printed on the paper, its binder will
penetrate into the internal drying of the paper due to the capillary action of the paper
fiber; Full play drying: After the ink is printed on the paper, only part of it will penetrate
into the paper, but most of it will be used.
What is the relationship between the fluidity and viscosity of ink?Why add desiccant
to the ink? When the drying capacity of the ink binder itself is not enough to meet the
time requirements of printing and chromaticity, we will add a drier to the ink to speed
up the drying. The drier can combine with the antioxidant in the ink to eliminate and
reduce the reaction of the antioxidant. In addition, the drier can directly absorb the
oxygen in the air, making it easier for the ink to obtain the oxygen needed for drying,
and accelerating oxidation drying.
