To accurately control the thickness of the ink layer, it is necessary to analyze according to the actual production conditions (such as ink properties, layout structure, temperature, printing press speed, paper ink absorption and surface smoothness, etc.). In general, under the conditions of low ambient temperature and relatively dry climatic conditions, the layout ink layer can be appropriately thinned; conversely, when the temperature is high, the printing ink layer should be thicker. When the surface of the printing paper is rough and the ink absorption is strong, the ink layer is appropriately thickened, and the layout is not easy to produce flowers. If the prints are mainly based on cable images, the ink layer should be thinner to avoid stencil printing. If printing a solid version, the ink layer should be thicker. In addition, when the printing press is fast, properly thickening the ink layer can achieve the desired ink color. In short, flexible use of the above methods in production can achieve better results.
When the viscosity of the ink is caused by improper ink viscosity or floating ink, an appropriate amount of No. 0 varnish can be added to the ink. When mixing, the varnish should be mixed in the ink.
