1. The requirements of the printing press require high-precision printing machine processing. In particular, the precision of the plate cylinder is required to be high. The general concentricity requirement is: TIR≤±15μm.
The press is required to have a high quality ceramic anilox roll. The anilox roller is required to have stable and uniform ink transfer performance, a higher number of anilox roller lines, a reasonable cable angle, and excellent wear resistance, capable of accurately providing a quantitative ink to the printing plate, and perfectly reproducing the printing product dot layer level. .
The printing press should have a high overprint accuracy and a stable tension control system so that each color sequence can accurately represent the pattern during overprinting and overlaying.
Easy to operate, responsive and stable pressure adjustment system. The pressure adjustment of flexographic printing is a very important operation link. Only under the cooperation of a reliable printing pressure adjustment system can adjust the pressure between the anilox roll and the plate roller and the platen roller and the substrate to the best state. Produce high quality prints.
2. Requirements for printing inks Printing inks require accurate hue and meet international or national quality standards. And require that each batch of hue should be consistent. Select ink properties that are suitable for the substrate and meet the conditions of use of the package.
The ink should ensure high color intensity, so that the use of high screen anilox roller, the lower the amount of ink transfer when the color is accurate, bright, full.
Reasonable drying speed. The drying speed must be determined in accordance with the characteristics of the substrate and the printing speed of the printing press.
The general nature of the ink requirements. The ink has stable physical and chemical properties. Such as water resistance, lightfastness and so on.
3, the requirements of the printing plate to obtain high-quality corrugated box printing its plate must be photosensitive resin plate (ie, flexo version). The current flexo editions are all developing towards thin editions, and their patterns are more powerful.
Plates should have good ink transfer properties. The plate should be able to transfer the ink from the anilox roller to the surface of the substrate smoothly and evenly.
The printing plate should have a reasonable relief height and dot shape of the dot network to ensure a clear reproduction of small dots and fine lines of yin and yang.
Plates should have good, uniform hardness. To ensure the smooth transfer of ink and controlled changes in dot network.
4. High-level printing operation technology is an indispensable requirement for obtaining high-quality printing products. A high-level operator should have a thorough understanding of printing equipment, printing inks, printing plates, and process conditions under different conditions. And can be used flexibly. He is always an active and active subject throughout the entire production system.
At present, there are many companies in the carton packaging industry has gradually embarked on the colorization of the road, but with Europe, the United States and even Southeast Asia there is still a certain gap. With the continuous development of domestic carton packaging production lines and various ancillary projects, we have every reason to believe that domestic color corrugated cartons will rapidly increase their popularity.
