Some Characteristics Of The Material Of The Cosmetic Hose

The printing plate used for printing is usually a copper plate, because the copper plate has a high printing resistance, and the plate making method is the same as that of the ordinary copper-zinc plate. The cosmetic hose printing machine is mainly composed of a printing plate cylinder, a rubber cylinder, an impression cylinder disc with a hose sleeve, a conveying mechanism, and an ink fountain.
Cosmetic hose printing Since the substrate is non-ferrous metal, it is necessary to print a layer of white ink or other background color ink on the surface of the hose before printing the graphics and texts to make a primer) and then the graphics and texts can be officially printed. After the background color is printed The ink needs to dry quickly. Only the next few colors can be printed, so the printed color is dried by an infrared drying device and then printed with pictures and texts. The embossing roller on the embossing cylinder is covered with a hose, but it does not rotate by itself. Only after it is in contact with the rubber roller, can it rotate at the same linear speed as the rubber cylinder. The diameter of the embossing cylinder is the same as that of the rubber cylinder , but the operation is different. The rubber cylinder rotates once, and the impression cylinder rotates 90° to complete the printing of a hose.
After the hose rotates for one week, it will leave the rubber cylinder, and the overprinting work of hose printing will come to an end, and then irradiate with infrared rays to make the imprint dry quickly and increase the brightness of the imprint. Toothpaste hose, hose shoe polish and medical ointment hose are printed by this method.
The ink used for metal hose printing should not only have heat resistance and light resistance, but also because the hose will encounter extrusion and twists during use, and it will often encounter water and humidity, so the ink should also meet the above conditions. The hose contains different substances, and the ink must also be resistant to erosion by these substances.
The laminated hose is the respective advantages of the two materials, and the laminated hose makes it a hose with the advantages of both, such as a laminated hose made of aluminum foil and plastic film, which has moisture resistance and weather resistance. The advantage is that it can be printed first and then laminated, so that the graphics and texts are in the plastic film layer, and the appearance is very beautiful. At the same time, it can be processed and formed after printing, changing the method of first forming and then curved surface printing, so that the photogravure method can be used Plastic printing is carried out, and laminated hoses are formed after lamination and molding.
Due to the extremely poor adhesion of plastic ink in plastic hose printing, surface treatment is required before printing. At present, the hot press transfer printing method is used abroad to print the pictures and texts on the transfer paper (that is, coated kraft paper). Substances that can produce adhesion, and then the transfer paper printed with graphics and text is in contact with the curved surface, and the transfer is carried out under heat pressure.
