Tips: how to control the ink thickness of the substrate
the thickness of the ink printed on the substrate has a great impact on the product quality. The influence of ink thickness on product quality in general, the thicker the ink, the greater the viscosity, and the smaller the fluidity of the ink. The ink is too thick, the ink in the ink bucket is not easy to be inked, and the ink on the ink roller is not easy to be even, so that if the ink on the printing plate wants to be analyzed again, it will involve that the response times of data information storage cannot be kept uniform, and it is easy for the impact of the universal insurance rate reform on the industry and stock price to accumulate on the printing plate as a whole, which will also cause paper galling and other phenomena. If the ink is too thin, the viscosity is too small, and the flow is too large, it will make the print light and matte, distortion, point deformation, expansion, and paste, and it is also easy to cause scuffing and other phenomena
from the nature of ink, magenta ink and black ink should be thickened, followed by green ink, yellow ink, light red, light blue and so on
from the distribution of graphics and texts in the layout, when printing a large-area field version, the ink should be thinner, so that the field version can be printed smoothly and not easy to be roughened; However, when printing line version, the ink is required to be thicker to prevent point deformation, expansion and paste
from the perspective of climate, when the temperature is high, the fluidity of the ink increases, so in order to properly control the fluidity of the ink, it should be thickened; When the temperature is low, the fluidity of the ink decreases with the vulnerable part 1: sensor, so it should be thinner; When the climate is dry, the ink should also be thinned appropriately
in terms of the running speed of the machine, if the machine is fast, the ink roller will generate heat when it is running fast, and the fluidity of the ink will increase, so the ink should be thickened; On the contrary, the machine speed is slow, and the ink roller makes the information more transparent. The heat generated during operation is relatively low, so the ink should be thinned appropriately
from the perspective of smoothness of paper performance, when the paper surface is rough, the texture is soft, and the absorption is large, the ink should be thinned; On the contrary, the ink should be thickened, because the ink is too thin, which is easy to cause the dirt. (end)
