Common printing quality problems of different types of label printing machines

flat pressing - intermittent paper feeding type label printing machines

flat pressing (tooth damage oblique pressing) there are many kinds of label machines, mainly from Japan, Taiwan, South Korea, etc., and the rest are domestic similar equipment. The advantages of this model are fast speed and high efficiency. It is suitable for small label production, especially for VIP label production. Suitable for general point, line and text printing. The disadvantage is that it is not suitable for large-scale field printing, he added "This kind of material is lighter than feather, and uneven ink color will appear during field printing.

circular flattening intermittent paper feeding type label printing machine

circular flattening label machine is represented by the B-100 series label machine of the former Japanese FSK company, and the localized equipment is lybq4230 label machine produced by Taihang printing factory, as well as a small number of similar equipment in Taiwan and South Korea. The advantage of this model is that it has a wide range of printing trials, which can be printed at both printing points Brush line text, suitable for large-area field printing. The disadvantage is that the speed is slow. Due to the transmission, the overprint accuracy is low, so it is not suitable for high-grade label printing

round pressing - continuous paper feeding rotary label printing machine

improve the label equipment of predecessors, represented by KO pack and sanky in Japan and labelman in Taiwan. The advantage of this model is that it is suitable for various types of label printing, especially for high-grade label printing. The disadvantage is that the printing plate roller and die-cutting plate roller need to be replaced for labels of different specifications, resulting in large customer investment, long printing adjustment and preparation time

semi rotating round pressing - back and forth paper feeding type label printing machine

this type of printing machine is represented by lp-300 of Japan Lintec company, and manufacturers of similar equipment include Yanqi company of Japan, wanman company of Taiwan, etc. The advantage of this kind of equipment is that labels within a certain size range can be printed on a unified roller without replacing the roller, "Dr. Hou Shifeng said. The disadvantage is that the machine itself has no web deviation correction system and random tension control, so the printing positioning accuracy completely depends on the cutting accuracy of printing materials

declare the mixing of two functions of experimental machine control and data processing:
