Packing hose printing principle and various kinds of technology

The hose printing ( 挠性管印刷) Is in the metal hose ( Tin lead alloy, aluminum, etc. ) And laminated hose, plastic hose, etc on the printing method.
metal hose printing is to use the principle of indirect rubber roller roller transfer printing graphic and finish printing.
domestic currently used toothpaste tube printing is to use an assembly line production, tin, lead, materials eight into port, the charged hoses, threading, background, printing graphic, baked in, lock cover, and filling and sealing packing completed at the end.
the hose printing plate is usually used in the copper plate, because the copper plate has high resistance force, plate making method is the same as the ordinary copper zinc plate plate making.
the hose printing machine is mainly composed of plate cylinder and rubber roller, hose set of embossing roller plate, transport agencies, ink fountain, etc.
the hose printing because of the non-ferrous metal substrates, so must, before printing graphic will be printed on a layer of white ink hose surface or other color ink to render) Before the formal printing graphic, after printing color need to make the ink work dry quickly. After a few color to seal, so is printed and the color via infrared dryers dry again. Overprint of graphic work, also is not like the traditional printed on paper embossing ZhuangJian, but three imprinting on the plate cylinder, at the same time overprint in rubber tube ( Due to the imprinting for field so overprint do not overlap) And then three color printing ink imprinting to the hose on the embossing roll at a time. Embossing roller embossing roller plate, with a hose, but won't turn in its own right, only and rubber roll after contact, to a line with rubber roller for rotate speed, the diameter of the impression cylinder plate and rubber roller diameter is the same, but different, rubber roller turn a week and embossing roller dial 90 ° and complete a hose printing.
hose rotation after a week, that is, from the rubber roller, the hose printing overprint work come to an end, with infrared irradiation, then to make imprinted dry quickly and to increase the brightness of imprinting.
toothpaste hose, hose shoe polish and medicinal ointment hose printing in this way.
metal hose printing ink, besides should have heat resistance, light fastness, also because the hose is in use when squeezing and twists and turns, also often meet with water and moisture, so the ink should be able to meet the above conditions. Within the hose material is different, ink must also can resist erosion of these material.
laminated tube is the Angle of the two substances of their respective advantages, framed composite hoses, make it has the advantages of both the hose, such as laminated hose by aluminum foil and plastic film, it has the advantages of wet resistance, weather resistance, can be printed and laminated, first make the graphic in the plastic film layer, and it's beautiful appearance, at the same time can also be printed after processing and molding, changed the way of printing, surface after molding first, so that you can use camera plastic in the form of gravure printing, after laminated, forming into laminated tubes.
plastic hose for plastic printing ink adhesion is poor, need to surface treatment before printing. Now using the thermal transfer printing method abroad, the graphic printed on transfer paper ( The kraft paper, coated with a coating) , color sequence is instead of color printing color sequence, then under the printing surface coating a layer of the heat treatment can produce adhesion material, the transfer paper and then put the printed graphic surface contact, under the thermal transfer printing.
