Detailed Description
The invention is further described below with reference to fig. 1.
The invention relates to a method for manufacturing a transparent photoetching film, which comprises the following steps: a-1, manufacturing a holographic relief laser mould pressing plate; a-2, selecting a film as a base material, coating UV paint on the front surface of the base material, and carrying out UV mould pressing to prepare a relief laser transparent film; a-3, printing and coloring the front surface of the base material in a positioning secondary printing mode; a-4, printing water washing white ink on the back surface of the base material; a-5, carrying out metal electroplating on the back of the base material; and A-6, cleaning the water-washed white ink on the substrate.
Specifically, in A-1, engraving the graphic information on the nickel plate by using a laser holographic laser engraving technology, and then manufacturing a mould pressing metal plate with good mechanical properties by using a vacuum coating or chemical electroplating method.
Because the laser film is an embossment positioning product, when the laser film is positioned by mould pressing, the position of holographic embossment laser printing needs to be calculated before plate making, embossment patterns are implanted into a specific position in a laser mould pressing plate, and then laser positioning mould pressing is carried out.
The specific operation is as follows: firstly, determining the size of printing on a machine, and splicing the files into plates according to plate cylinder numbers; the manufactured relief laser patterns are spliced according to the splicing size arrangement requirement of a plate cylinder, and an electric eye color block is placed above a cross line according to the length of each printing plate during splicing; the nickel plate is manufactured according to the spliced specification plate, the temperature and the speed of batch operation are kept the same in the die pressing, electroplating and cutting operations, and different expansion and contraction amounts of materials caused by different operation conditions are avoided.
In addition, when the mould pressing plate is carved, the cross gauge lines are complete, and the gripping opening and the pull gauge of the cross lines are provided with stepped arrow marks and cutting lines. Meanwhile, a color block of the positioning electric eye is carved, and a color code identification strip is adopted, so that the color code sensor can conveniently identify the color code. Typically the identification color bars have a frosting effect.
Specifically, in A-2, the base material is a PET film with a specification of 22 u. The UV coating is coated on the PET film, proper viscosity and coating amount are ensured when the UV coating is coated, and the UV coating is coated in a sealed, dust-free, constant-temperature and constant-humidity environment. The coating is used as a first procedure, a gravure process is adopted to coat the UV coating, the coating thickness is 0.15mm to 0.3mm, the depth of field effect of the embossment can be directly influenced by the coating thickness, and the thickness of the coating layer is determined by product design. And (4) coating UV paint and then carrying out a UV mould pressing procedure to prepare the relief laser transparent film.
Specifically, in A-3, a printing plate is produced according to the document of the assembled plate. And (6) film is firstly discharged, and the nesting condition of the laser film manufactured by die pressing is checked according to the film. Since the embossing causes the material to deform telescopically, the layout needs to be adjusted appropriately. After the film is spliced, the film is sleeved with a Chinese character mi grid, the position coordinate where the film moves is found out, the operation can be carried out on a computer according to data, the spliced plate is adjusted by the computer, then the film is discharged for overprint check, and the computer direct plate making can be carried out after the correctness is confirmed.
Printing on a machine after plate sticking according to the number of the used plate cylinder, opening the secondary overprinting function, setting the tension for retraction and extension, setting the overprinting electric eye function, and producing by using transparent ink, wherein the registration precision is kept to be +/-0.2 mm.
Specifically, in A-4, the PET film is printed with water washing white ink on the reverse side, a specific area on the reverse side of the substrate is not printed with water washing white ink, the specific area is a transparent position, and the specific area is subjected to metal plating in A-5. A-3 and A-4 are combined, and a positioning secondary printing mode of positioning printing on the front surface of the base material and positioning printing of washing white ink on the back surface is adopted.
The printing workshop keeps the ambient temperature at 18-20 ℃ and the humidity at 50-70%, eliminates static electricity generated when a printed matter rubs with each paper feeding roller, and avoids the printed matter from being heated and deformed due to high temperature by applying a water cooling roller.
Specifically, in a-5, after the die pressing of the laser pattern is completed, a layer of metal, such as metal foil, needs to be sprayed on the laser pattern to achieve the platinum relief effect, and a vacuum aluminum plating machine is used for achieving the platinum relief effect. After vacuum aluminum plating, the surface of the laser film is subjected to surface treatment by adopting a varnish coating or corona mode so as to improve printability, and a proper treatment mode can be selected according to different surface properties of the laser film.
Specifically, in A-6, the printed and electroplated film of the coil is washed by water, and the aluminum layer at the position printed with the washing white ink on the back surface of the substrate after aluminum plating has insufficient adhesive force and is easily washed away by water, so that the transparent effect is realized. And after cleaning, adopting a flexible plate thermal drying process for treatment.
The coil subjected to the A-6 aluminum washing treatment is compounded or coated for use according to application requirements.
The transparent photoetching film prepared by the method can increase the expressive force, uniqueness and anti-counterfeiting function of product packaging, enhance the shelf effect of product display, attract the eyes of customers and increase the sales volume of products.
While the embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
