Abstract
The invention relates to the holographic anti-counterfeiting printing industry, in particular to a transfer method for a holographic anti-counterfeiting molded film. The invention provides the transfer method for the holographic anti-counterfeiting molded film, which can replace a pattern transfer method which is used for molding transfer of a film used by a nickel plate to form a molded film. A holographic nickel plate is produced and a titanium nitride layer is formed on a polyethylenetherephtalate (PET) base film through molding transfer and vacuum titanium plating to form a holographic titanium-film mother plate film band; and the mother plate film band and a base film band are abut-pressed at certain temperature and pressure, a coating layer part is softened in advance, ultraviolet (UV) adhesive is used for post-curing to form a holographic film, and then vacuum aluminum plating is performed to form a holographic aluminum-plated film. The transfer method for the holographic anti-counterfeiting molded film has the advantages that the original molding method that the nickel plate is required to be used as a mother plate for molding transfer is changed, the cost can be greatly saved and the molding transfer efficiency is improved.
Description
Technical field
The present invention relates to a kind of holographic false proof printing industry, particularly a kind of transfer method of holographic anti-counterfeiting film press mold.
Background technology
The packages printing industry fast development of China, the use of specialties progressively enlarges, particularly the use of various laser transfer membranes; Enjoy consumer's welcome because of the pattern that its surface is bright and beautiful; But because that it is made is complicated, with high costs and have some to hinder, especially the cost of plate-making occupies height always; And the template of a high price of processing only can adopt the method for transfer to print about about 10,000; If can prolong the service life of this template, also can reduce cost greatly, change the mode of production that mold pressing is shifted; Make the radium-shine printing sexual revolution that leads to a leap, solving template cost problem is the problem that engineers and technicians press for solution; The case that the film that also not seeing in the prior art has the present invention to shift shifts as template.
Summary of the invention
The object of the invention is exactly in order to overcome defective that above-mentioned prior art exists, a kind of film that can the replacement nickel plate uses is provided, is applied to the transfer method of holographic anti-counterfeiting film press mold that the design transfer method of mould film was shifted, formed in mold pressing.
The objective of the invention is to accomplish through following technical scheme:
The transfer method of a kind of holographic anti-counterfeiting film press mold of the present invention, concrete steps are following:
The first step: make one of holographic nickel plate;
Second step: on the PET basement membrane; Adopt moulding press that holographic nickel template die is pressed to shift and make the PET film that has the holographic information layer that is used for motherboard; And vacuum titanizing on PET film mother matrix, promptly plating one deck titanium nitride layer on PET film mother matrix is processed banded holographic titanium film motherboard film band;
The 3rd the step: with the holographic titanium film mother matrix of band shape film band as the mother matrix band; By let off roll and wind-up roll support and keep certain force of strain, certain molding temperature, in the positioned beneath of corresponding mother matrix band the basement membrane that needs to shift pattern being arranged also is that the film band is by another let off roll and wind-up roll support, and said basement membrane film band is the basement membrane film band that is coated with electrochemical aluminum paint and UV glue; Above the mother matrix band and below the basement membrane; The a pair of working roll that has uniform temperature, pressure to pressing is set, preheats mother matrix band and basement membrane film band earlier, coating layer portion is softening; Through said each other to the working roll of pressing to pressing the pattern that shifts on the mother matrix band on basement membrane; Constitute holographic optical line Information Level, curing mode behind the employing UV glue forms holographic film;
The 4th step: the holographic film of rolling is carried out vacuum aluminum-coated, as on holographic optical line Information Level, to form one deck light specular aluminium rete, process holographic aluminized film, accomplish the transfer of holographic anti-counterfeiting film press mold.
The method of a kind of mould film of the present invention, wherein: said titanium nitride coating thickness is 300-500A, holographic groove is clear.
The method of a kind of mould film of the present invention, wherein: said top working roll adopts 120-140 ℃ temperature, and bottom working roll adopts 80-100 ℃ temperature.
The method of a kind of mould film of the present invention, wherein: upper working rolls and lower working rolls preheats film, and coating layer portion is softening, and upper working rolls and lower working rolls is 20 handkerchiefs-30 handkerchiefs to the film moulding pressure, and pressure is delivered on the transfer membrane.
The method of a kind of mould film of the present invention, wherein: said UV glue is: have the UV glue that high-speed light is solidified.
The method of a kind of mould film of the present invention, wherein: by the vacuum titanizing of hard metal substitute that can vacuum evaporation in said second step.
The method of a kind of mould film of the present invention, wherein: said vacuum evaporation metal comprises crome metal, carries out vacuum chromium-coated.
The present invention has following remarkable advantage: the present invention be intended to traditional, make the nickel plate complicated, that cost is high and change into banded holographic titanium film mother matrix film band that employing can the replacement nickel plate as the original holographic transfer method of mother matrix and carry out holography as mother matrix and shift, i.e. the transformation of press moulding mode, specifically distinguishing is to be originally transfer membrane is aluminized; Be that titanium nitride has high rigidity with the transfer membrane titanium-nitride now, satisfy mold pressing and shift requirement; The holographic film of titanium-nitride is as the mother matrix in the transfer method, is equivalent to the titanium nitride film of made as version usefulness, in the time of complex process when practicing thrift nickel sheet material material and making nickel plate; Also increase the transfer area of version relatively, prolonged the service life of nickel plate relatively, greatly reduced the cost of producing transfer membrane; Specifically be, a nickel plate is wide 500 millimeters-600 millimeters, and nickel plate can transfer printing 10000-15000 rice; And the banded holographic titanium film mother matrix film band of a myriametre that is shifted out by a nickel plate now carries out trans-printing as mother matrix, and mother matrix will be up to ten thousand times amplification, improve the transfer efficiency of mother matrix greatly; Also do not worry the sticking version phenomenon when can produce common mold pressing shifts, because the titanium nitride case hardness is high, plated film can be realized very thin; Can not hide the information of holographic information layer, the image information under can seeing through titanium nitride layer as the effect of aluminizing on the Information Level of facial mask, titanium nitride coating is thinned to and can the groove of holography not be filled up; Can be with the holographic information complete copy, titanium can be realized vapor deposition, holographic film is the vacuum plating; And be to plate uniformly, can form homogeneous coating, because of its dyne value height; Can mold pressing; This method is a kind of novel moulded branch mode, can practice thrift cost greatly, improves the efficient that mold pressing is shifted.
