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.

Ink printing with bright color, good adaptability, ink is a certain fluidity of paste adhesive, viscosity, negative, thixotropy, liquidity, dry decides the performance of ink, printing ink to add fertilizer, to improve the ink printing eligibility, such as viscosity, viscosity, dry, etc. With the development of printing technology, the variety of ink is increasing, and there are many methods of classification.If classified according to the printing method, there are the following five types: Relief printing ink: book black ink, rotary black ink, color relief ink, etc. Lithographic printing ink: offset gloss resin ink, offset rotary ink, etc. Intaglio printing ink: photogravure ink, engraving intaglio ink, etc. Hole printing ink: copying ink, screen printing ink, etc. Special printing ink: foaming ink, magnetic ink, fluorescent ink, conductive ink, etc. The configuration process of ink is more complex, generally pigment, binder and various additives, in accordance with a certain proportion, first mixed into oil paste in the ink mixer, and then in the roller grinder or repeatedly grinding, so that the pigment to fine particles, evenly dispersed in the binder and made. Although there are many kinds of ink color, but the color and bronzing process is very different from the above, let's look at the effect of bronzing. The effect of hot stamping paper has the advantage of shining.
