Information

The printing plate used in domestic cosmetic tube printing is usually copper plate, because the copper plate has higher printing resistance, and the plate making method is the same as that of ordinary copper-zinc plate.

The cosmetic tube printing machine is mainly composed of a printing plate cylinder, a rubber cylinder, an impression cylinder plate with a hose, a conveying mechanism, an ink fountain, etc.

Because the substrate for cosmetic tube printing is non-ferrous metal, it is necessary to print a layer of white ink or other background ink on the surface of the tube before printing the graphics and text. Then the graphics and text can be formally printed. After the background color is printed The ink needs to be dried quickly. Only the next few colors can be printed, so the printed color is dried by an infrared drying device before printing graphics and text.

The overprinting work of graphics and text is not realized like traditional printing on the embossed paper, but the imprints on the three printing plate cylinders, which are overprinted on the rubber quilt at the same time (because the imprints are solid, the overprints are combined No overlap), and then transfer the three-color ink print to the tube on the embossing roller at a time. The impression roller on the impression cylinder is covered with a hose, but it does not rotate by itself. Only after contact with the squeegee, can it rotate at the same linear speed as the squeegee. The diameter of the impression cylinder is the same as the diameter of the squeegee. , But the operation is different, the blanket cylinder rotates once, and the impression cylinder rotates 90° to complete the printing of a tube. To

To

After the cosmetic tube rotates once, it will be separated from the rubber cylinder, and the overprinting work of the tube printing has come to an end. Then it is irradiated with infrared rays to quickly dry the print and increase the brightness of the print.

Toothpaste hoses, hoses, shoe polish and medical ointment hoses are printed in this way.

The printing ink for metal hoses should not only have heat resistance and light resistance, but also because the hose will encounter squeezing and tortuous when in use, but also often encounter water and humidity, so the ink should also meet the above conditions. The materials in the hose are different, and the ink must also be able to resist the erosion of these materials.

Laminated hose is a hose that utilizes the respective advantages of two materials and is laminated to a synthetic hose to make it have the advantages of both. For example, a laminated hose made of aluminum foil and plastic film has the advantages of moisture resistance and weather resistance. , It can be printed and then laminated, so that the graphics and text are in the plastic film layer, and the appearance is very beautiful. At the same time, it can be processed and formed after printing, and the method of first forming and then curved printing is changed, so that it can be carried out by photogravure Plastic printing, laminating and forming into a laminated hose.

Because of the poor adhesion of plastic ink in the printing of cosmetic hose hoses, surface treatment is required for printing. At present, the hot press transfer method is used in foreign countries to print pictures and texts on transfer paper (that is, coated kraft paper), the color sequence is the opposite color sequence of color printing, and then a layer of heat treatment is applied on the printing surface Substances that can produce adhesion, and then the transfer paper with graphics and text is contacted with the curved surface, and the transfer is carried out under heat and pressure.
