The production method that a kind of paper printed matter anti-counterfeiting image hot pressing is shifted
Technical field
The present invention relates to the field of anti-counterfeit technology of paper printed matter, be specifically related to the production method that a kind of paper printed matter anti-counterfeiting image hot pressing is shifted.
Background technology
The anti-fake processing method of image false-proof packing mainly contains following several types at present: 1, soft packaging bag; Compound with laser film (anti-counterfeiting image on the light film, impress come out) and common plastic film, printing forms laser material soft packaging bag (claiming radium-shine soft packaging bag again) then.2, Hard Roll pack, laser film and paperboard are compound, and printing forms the laser material hard pack then.3, citicall limited aluminium paper directly is made in (the aluminium lamination plating is being had on the plastic sheeting of laser pattern, and the aluminium lamination adhesive transfer of plating is to paper surface) on the paper that plated aluminium lamination with radium-shine laser anti-counterfeit image, and all kinds of packaging products print on radium-shine paper again.4, through stamping systems---the high-grade electrochemical aluminium product of laser treatment, through gold stamping processing technology the stamping systems of laser treatment is transferred to the printing package article surface, this method is used on the papery packaging product more.5, in the printed matter surface coating UV gloss oil; Before the UV gloss oil solidifies; With laser film (security pattern impresses on the light film) pressing with it, send into simultaneously under the UV lamp and solidify, after the curing laser film and printed matter are peeled off; Printed matter surface can form laser anti-counterfeit pattern, and this method is used for paper printed matter more.6, on paper, directly print hologram; On the paper or cardboard of existing printing-ink; Coating one deck thermoplasticity holographic dope obtains the smooth coating of one deck light, as the memory layer of hologram after dry, press polish are handled earlier; On special holographic paper moulding press, carry out contour forging again, form the hologram of transparent diffraction at last at print surface.Above method exists difficulty of processing big, complex process, and cost is higher, and the medium that in process of manufacture, need to adopt solvent based coating or UV gloss oil, aluminium powder, copper powder etc. to shift as security pattern, production process and not environmental protection of product or incomplete environmental protection.
Summary of the invention
The production method that the object of the present invention is to provide a kind of paper printed matter anti-counterfeiting image hot pressing to shift; Shift chemical medium and all adopt water paint; Paper printed matter anti-counterfeiting image and surperficial glazing are handled and are carried out synchronously, and this method antifalse effect is good, and production process and the complete environmental protection of product.The present invention designs the production method that a kind of paper printed matter anti-counterfeiting image hot pressing is shifted, and it is characterized in that it comprises following steps: (1) is at surface coated one deck aqueous basecoat coating of paper printed matter, and drying; (2) coating one deck aqueous transfer coating on the radium-shine film of the BOPP/PET that has the laser anti-counterfeit image, and oven dry; (3) will have aqueous transfer coating coating layer and the direct heat pressure adhesive of aqueous basecoat coating coating layer of paper printed matter surface on the radium-shine film of BOPP/PET of laser anti-counterfeit image; (4) paper printed matter behind the heat pressure adhesive and the BOPP/PET film that has a laser anti-counterfeit image are carried out timely cool drying; (5) the radium-shine film of the BOPP/PET that has the laser anti-counterfeit image attached on the paper printed matter behind the heat pressure adhesive cool drying is peeled off; (6) rolling has the radium-shine film of laser anti-counterfeit image B OPP/PET, the recycling of arrangement back.The present invention changes the conventional laser image false-proof and produces transfer method; Utilize the environmental protection water soluble paint to realize the transfer of duplicating of laser anti-counterfeit image on the radium-shine film of BOPP/PET immediately at paper printed matter surface fully; Having the radium-shine film of laser anti-counterfeit image B OPP/PET can recycle repeatedly, has saved production cost greatly.

Accompanying drawing 1 is a process flow diagram of the present invention,
The product structure sketch map that accompanying drawing 2 is produced for technology of the present invention,
Below in conjunction with accompanying drawing and instance the present invention is elaborated.
The specific embodiment
(1) on the surface of paper printed matter 1, is coated with one deck aqueous basecoat coating 2 in advance, and lets its bone dry;
(2) on the radium-shine film 3 of the BOPP/PET that has the laser anti-counterfeit image with hot pressing coating transfer equipment coating one deck aqueous transfer coating 4, and be allowed to condition on the drying system of this equipment dry; (3) shift unit (shifting) to aqueous transfer coating 4 coating layers on the radium-shine film 3 of the BOPP/PET that has the laser anti-counterfeit image in hot pressing coating transfer equipment or on line hot pressing and go up directly the aqueous basecoat coating 2 coating layers direct heat pressure adhesive surperficial with paper printed matter 1 to the printing of web printing product on line, glazing, hot pressing; (4) paper printed matter behind the heat pressure adhesive 1 and have the timely cool drying of cool drying system that the radium-shine film 3 of the BOPP/PET of laser anti-counterfeit image gets into hot pressing coating transfer equipments; With the excessive deformation of the radium-shine film 3 of BOPP/PET that prevents to have the laser anti-counterfeit image, so that recycling; (5) after thermocompression bonded merges cool drying; Paper printed matter 1 is peeled off with BOPP/PET film 3 immediately; Paper printed matter 1 surface that aqueous transfer coating 4 dope layers on the radium-shine film 3 of BOPP/PET are transferred; And with on the radium-shine film 3 of BOPP/PET fixedly anti-counterfeiting image follow the surface that aqueous transfer coating 4 directly duplicates aqueous basecoat coating 2 coating layers of transferring to paper printed matter 1; Realize that duplicating of laser anti-counterfeit image shifted the paper printed matter printing surface on the radium-shine film of BOPP/PET, accomplish the surperficial glazing of paper printed matter simultaneously and handle; (6) recyclings are put in the radium-shine film 3 online rollings of BOPP/PET that still have the laser anti-counterfeit image in order.5 is printing ink layer on the paper printed matter 1 among the figure.Wherein the bottom-coating in the step (1) is water miscible, has closing property of heat pressure adhesive, is full version coating, can select the product of Shanghai chin or cheek letter Chemical Industry Science Co., Ltd for use, and model is WR802.Transfer coatings in the step (2) is water-soluble, under certain temperature and pressure, be prone to step (1) in bottom-coating sticking and fuse into one, be convenient to realize that the paper film peels off, can select the product of Shanghai chin or cheek letter Chemical Industry Science Co., Ltd for use, model SW201; Aqueous transfer coating need be expired version and is coated on the radium-shine face of the BOPP/PET that has laser anti-counterfeit pattern; Printed matter surface can select for use BOPP/PET light film to adopt this production method to realize that its surface brightness can reach the coating brightness of UV gloss oil fully as not needing security pattern.
BOPP film in the literary composition is a biaxially oriented polypropylene film, and the PET film is a polyester film.
