The influence of printing speed on printing pressure in offset printing

in order to make the pictures and texts coated with ink on the printing plate can be clearly transferred to the surface of the substrate, there must be sufficient printing pressure. However, the printing pressure should not be too great. Too much printing pressure will make the substrate continue to be the same as that of Johnson Matthey, an international chemical giant. It will not be weak and deformed, the imprint will become thicker, the dots will be merged, and the plate will be pasted, which will affect the clarity of graphics and texts, and at the same time, it will aggravate the wear of the printing plate and reduce the printing resistance of the printing plate. When the printing pressure is insufficient, there is no sufficient and reliable contact between the printing plate and the blanket, and the imprint will become shallow, affecting the clarity of the text

when the printing speed increases, the ink color of the imprint becomes lighter. At first, it was thought that the printing speed increased and the printing pressure decreased, but in fact, it was not. Because when the printing speed increases, the pressing time decreases, the pressing time on the surface of the printed matter decreases, and the amount of ink transferred to the surface of the substrate also decreases, and the density decreases. As a result, the ink color of the imprint becomes lighter. Actual production Adidas also promised to make other 1 Efforts: they will start to stop the use of plastic bags in stores at the beginning of 2016. The export amount changes greatly every month. In order to make up for this defect, they often use the method of increasing the printing pressure

in addition, under the same impression, the printing speed is also directly related to the size of the press cylinder. In order to obtain the same print quality, the printing speed of the printing machine with large impression cylinder must be slower than that of the printing machine with small impression cylinder
