In 2008, the sales volume of gravure printing machines in China was about 110 units, and the annual demand is expected to maintain a growth rate of 10%-12%. In 2009, the sales volume of domestic high-end plastic concave machines was about 360-380 units, and the annual growth rate in the next five years will increase. The speed is expected to be more than 15%. 2. The number of domestic gravure printing presses is decreasing year by year. The company's products are positioned in the middle and high-end market, and will benefit from the “import substitution†process of products such as paper recess machines. This article will introduce you. Which supplier is good for Beijing gravure printing machine.
The printing speed of the gravure printing machine is mainly determined by the length of the transmission distance between the colors of the printing machine. Since there will be color registration on the printed product, if the ink of the front color is not dried, the ink of the latter color will dissolve the ink in front, which will cause color problem. Therefore, if the distance between the inks of the gravure printing machine is larger, the longer the natural drying time, the higher the printing speed. On the contrary, it is difficult to increase the printing speed.
Secondly, the printing speed is determined by the effect of the drying box. The drying effect of the drying box is good, and the more thorough the drying of the ink, the not only the ink of the front color can be dissolved, and the residual of the solvent is relatively reduced. Gravure inks are blown dry by hot air rather than hot baked. First, when the gravure ink is heated, the conjunctiva is very fast, and the coating of the color film may affect the volatilization of the solvent in the ink, which may cause the ink to dry.
The technique of transferring the printing and finishing of the printing plate of Jinan gravure printing machine is called plate printing; the crafting technique of transferring the printing without using the printing plate is called non-printing. In general, the printing machine of the Jinan gravure printing machine is mainly composed of a paper feeding portion, a printing portion and a delivery portion.
