Ink in the transfer, distribution (from the ink hopper ink, after complex transfer and distribution, until the smooth transfer to the surface of the printing sheet to form a blot), the flow phenomenon is called the transfer of ink, it is the main body of ink operation adaptability.  The transfer of ink can be understood from two aspects: On the one hand, ink transfer, uniform ink and ink roller transfer; On the other hand is the ink between the plate and the blanket, the blanket and the transfer between the sheet. On the other hand is the ink between the plate and the blanket, the blanket and the transfer between the sheet. The former is mainly affected by inking and transmission, while the latter is also affected by printing conditions (such as printing type, printing speed, printing pressure, etc.) and blanket, paper.  That is, the transfer of ink is displayed in the whole transfer, distribution and ink layer separation (or splitting) process, which is of great significance to offset printing. The quality of ink transfer, mainly depends on the ink drawing and viscosity, but also its wettability, viscosity, yield value, thixotropy, surface tension and so on.

After ink roller output, the flow phenomenon is called ink transfer. In the process of printing, the thickness and uniformity of the ink layer on the surface of the image and text of the plate are achieved by a series of ink rollers. Therefore, the quality of ink transfer is directly related to the ink distribution and distribution, and the smooth transfer of ink in the whole process. Generally speaking, the process from the ink hopper to the ink plate depends on the viscosity, drawing and thixotropy of the ink itself. (1)Under normal circumstances, when the drawing property and viscosity are appropriate, the ink shows better transmission, and the ink volume distribution is also better; (2)When the drawing property and viscosity are too large, the transitivity becomes bad, and the ink distribution becomes worse; (3)When the ink is too long, it is easy to cause the phenomenon of flying ink. Our waterborne coating products are widely used in waterborne environmental protection coatings, waterproof coatings, Marine coatings and so on. Our coating industry products, most can be used as paint, ink and other solvents, such as propylene glycol methyl ether, diethylene glycol butyl ether, diethylene glycol diethyl ether and so on, propylene glycol butyl ether is one of the most effective film forming additives in many waterborne coatings.

Ink output by the ink hopper flow phenomenon called ink ink. When the ink is output by the ink roller, it is only affected by the external force of the ink roller. The flow conditions are mainly the gravity and surface tension of the ink itself, and the inking of the ink depends on its own fluidity, but also on its own flow, viscosity, yield value, thixotropy, drawing and other rheological properties. In the process of printing, the inking quality of ink directly affects the amount of ink supply per unit time, and the thickness of ink layer in the process of transmission and transfer.In actual adjust the volume of ink the ink printing, in addition to adjust the ink fountain roller speed (or Angle), or local regulation ink fountain blade clearance, more should pay attention to the automatic or manual of ink mixing, and change the ink yield value and thixotropy, ensure that within every moment is a constant amount of ink, printing ink can't normal is passed on to the ink fountain roller, form the hysteresis phenomenon of ink, Resulting in poor ink supply or interruption of ink supply. sinogracechemical produces all kinds of ink raw materials, welcome to consult

The fluidity of ink includes viscosity, adhesion, viscoelasticity, and yield value and thixotropy.It mainly depends on the nature of pigment and binder, and its manufacturing process, the content of binder directly affects the fluidity of ink. In the printing press, the flow phenomenon is mainly manifested in the following three aspects: (1) When the container is poured into the ink hopper, the ink is easy to flow; Otherwise, (2) when output by the ink hopper, easy ink is called good fluidity; Otherwise, the difference. (3) in uniform ink, ink and ink, easy to spread, transfer, transfer called good liquidity; Vice versa. In the process of printing, it is important to control the flow of ink correctly. Moderate fluidity can not only ensure the normal flow of ink on the printing press, but also make the blot uniform and smooth. (1) If the fluidity is too large, the ink will slip on the ink roller, resulting in the expansion of the blot geometry, damage the picture level, and increase the ink penetration on the paper; (2) If the liquidity is too small, the ink supply is abnormal, so that the ink distribution is not uniform, can not ensure the uniformity of printing ink, and even due to the lack of ink caused by the layout of the version.
