How to control the ink thickness of the substrate

The thickness of the ink printed on the substrate affects the quality of the product. The effect of ink thickness on product quality In general, the thicker the ink, the greater its viscosity and the less fluidity of the ink. The ink is too thick, the ink in the ink fountain is not easy to ink, and the ink on the ink roller is not easy to make even, so that the ink on the printing plate can not maintain uniform, and it is easy to accumulate on the printing plate, and can also cause phenomena such as paper pulling. If the ink is too thin, the viscosity is too small, and the fluidity is too large, the printing product will be light and distorted, the distortion of the dots will be expanded, and the paste will be blurred. At the same time, the phenomenon of dirtiness will be easily caused.

From the nature of the ink, magenta ink and black ink should be thickened, followed by blue ink, yellow ink, light red, light blue, and so on.

From the layout of the layout of the layout, in the printing of large-scale field version, the ink should be thinned, the field version can be printed in plain clothes, not easy to pull the hair; but when printing cable version, the ink thickness is required to prevent the deformation of the network point to expand, Hair paste.

From the climatic point of view, when the temperature is high, the fluidity of the ink increases. Therefore, in order to properly control the fluidity of the ink, the thickness of the ink should be adjusted. When the temperature is low, the fluidity of the ink is reduced. Therefore, the thickness of the ink should be reduced. When the climate is dry, the ink should also be thinned.

From the speed of machine operation, the speed of the machine is fast. When the ink roller is in rapid operation, it will generate heat and the fluidity of the ink will increase. Therefore, the ink should be thickened; on the contrary, the machine speed is slow, and the heat generated by the ink roller is running. Relatively lower, so the ink should be thinned properly.
