The number of lines added to the printing plate is constrained by the number of lines on the mesh roller, and the ratio between the two is required to be at least 1:5. A 400L/n mesh roller can achieve a printing plate speed of up to 80L/h, and a high line count can easily cause plate sticking and turtle lines. So adding more network cables is not necessarily better. The printing effect of 80L/h and 75L/h will not have a significant difference in terms of precision. The screen angle for flexographic printing mainly adopts two angles: 7, 37, 67, 82, and 7, 22, 52, 82, depending on the angle of the mesh roller. But from the perspective of adding a network, it should be based on the actual product and cannot be a one size fits all approach. For monochrome mesh patterns with straight lines, the mesh angle must be 45 degrees or 0 degrees, otherwise the edges of the mesh pattern will show obvious jagged edges. The selection of the angle of the overlay pattern should be based on the principle that the hue angle of the main color tone of the product pattern differs by 30 degrees. If the skin tone of a portrait is mainly yellow, then the color difference between magenta and yellow should be above 30 degrees; If the scenery is dominated by green tones, the color difference between cyan and yellow should be above 30 degrees, otherwise it is easy to produce turtle patterns. Before making the plate, conduct a sample simulation of screening to determine the optimal screening method. Discrete network points have adopted certain screening techniques to increase the anti-counterfeiting of products.
