Abstract
The invention discloses a method for laser imprinting transfer on wrapping paper. The main techniques of the method comprise the following steps: A. UV oil is pre-coated on the paper by a screen printing method; namely in printing, the UV oil is poured into one end of a screen printing plate, a scraper blade exerts certain pressure in the UV oil position on the screen printing plate, and at the same time the UV oil moves to the other end of the screen printing plate; the UV oil is extruded on the paper by the scraper blade from parts of oil penetrating meshes in moving; B. the coating surface of a laser film is touched with the UV oil surface on the paper, and the UV oil is stuck to the surface of the laser film with the laser coating; C. the irradiation of a UV light solidifies the UV oil; D. the laser film is stripped; and E. the dried UV oil of the laser coating on the laser film completes laser transfer on the paper. In order to overcome the defects of bad coating quality, insufficient overprinting precision and limited coating amount of the existing method for laser imprinting transfer, the invention provides the method for laser imprinting transfer with thick UV oil layer and high precision.
Description
[technical field]
The present invention relates to a kind of method that laser imprinting shifts on wrapping paper.
[background technology]
For the wrapping paper that makes cigarette case, toothbrush case, packing box, Front cover of book and periodical etc. is attractive in appearance beautiful, usually the radium-shine coating on the radium-shine film is shifted being impressed on the wrapping paper, wrapping paper has just had laser effect, and is brilliant.In outstanding space of a whole page theme, also improved the printing product surface decoration result, to reach the purpose that printing is made something perfect even more perfect.
For the radium-shine coating on the radium-shine film is bonded on the wrapping paper, just need be on paper precoating UV oil, generally all be to adopt the local UV machine to apply in the prior art.The local UV machine applies, and adopts the UV oil with higher brightness, transparency and wearability, is stained with UV oil on the applicator roll, thereby the applicator roll rotation is coated in UV oil on the wrapping paper.
Because local UV machine applicator roll is a resin material, soft and not wear-resisting, this just causes its coating quality not good: the fine rule width of coating must be more than 3mm, and chromatography precision only is 1mm; There is its coating method to belong to letterpress again, causes coated weight also very limited, cause the radium-shine coating of energy adhesion not enough, DeGrain.
[summary of the invention]
The objective of the invention is to have the deficiency that laser imprinting transfer method coating quality is not good, chromatography precision is not enough, coated weight is limited now and the laser imprinting transfer method that a kind of UV oil reservoir is abundant, precision is high that provides in order to overcome.
In order to solve the technical problem of above-mentioned existence, the present invention adopts following technical proposal:
A kind of method that laser imprinting shifts on wrapping paper is characterized in that may further comprise the steps:
The method precoating UV oil of A, usefulness serigraphy on paper; On screen printing forme one end, pour UV oil into when promptly printing, apply certain pressure, move towards the screen printing forme other end simultaneously with the UV oil position of scraper plate on screen printing forme; UV oil is expressed on the paper in by scraper blade from parts of oil penetrating meshes in moving;
B, radium-shine membrane coat face is contacted with UV pasta on the paper, UV oil clings the side that radium-shine film has radium-shine coating;
C, UV light irradiation solidify UV oil;
D, peel off radium-shine film;
Radium-shine coating on E, the radium-shine film is bonded at by dry UV oil and finishes radium-shine transfer on the paper.
The present invention compared with prior art has following advantage:
1, the thickness of serigraphy UV oil is 30-100 μ m in this method, and is high more a lot of than thickness that local UV machine prints 5 μ m, and can adjust according to products characteristics, makes radium-shine transfer quality obtain very big reinforcement;
2, in this method since serigraphy core intersection and precision all than local UV machine height, so minimum lines can print to 1mm or lower, and the minimum line thickness that traditional local UV machine laser imprinting transfer techniques can be accomplished is 3mm;
3, owing to the soft easy deformation of resin-coating roller quality in traditional local UV machine, its chromatography precision can only reach 1mm, and the precision of serigraphy UV can reach 0.2-0.5mm in this method.
[specific embodiment]
Below in conjunction with the specific embodiment the present invention is described in further detail:
A kind of method that laser imprinting shifts on wrapping paper may further comprise the steps:
The method precoating UV oil of A, usefulness serigraphy on paper;
B, radium-shine membrane coat face is contacted with UV pasta on the paper, UV oil clings the side that radium-shine film has radium-shine coating;
C, ultraviolet (UV) light irradiation solidify UV oil;
D, peel off radium-shine film;
Radium-shine coating on E, the radium-shine film is bonded at by dry UV oil and finishes radium-shine transfer on the paper.
The serigraphy basic principle is: utilize the saturating UV oil of screen printing forme part mesh, the part mesh not basic principle of saturating UV oil prints.
The method of serigraphy is: pour UV oil into during printing on screen printing forme one end, apply certain pressure with the UV oil position of scraper plate on screen printing forme, move towards the screen printing forme other end simultaneously; UV oil is expressed on the paper from the mesh of saturating oil by scraper plate in moving.
Owing to the viscous effect of UV oil makes the trace set within limits, the printing process middle scraper is line with screen printing forme and paper all the time and contacts, contact wire moves with scraper plate and moves, owing to keep certain clearance between screen printing forme and the paper, screen printing forme when making printing produces reaction force to scraper plate by self tension force, and this reaction force is called screen resilience.
Because the effect of screen resilience makes screen printing forme and paper only be portable line and contact, and screen printing forme other parts and paper is disengaged position, make UV oil and screen printing forme generation rhegmagenesis, guarantee the printed dimensions precision and avoided the set-off paper.Lifted after scraper plate is scraped the whole silk screen space of a whole page, screen printing forme also lifts simultaneously, and UV oil is gently scraped back initial position.So far be a print stroke.
UV oil (UV is a ultraviolet light, is the abbreviation of English Ultraviolet Rays) is meant a class clear dope of ultraviolet curing, this coating adhesive clear transparent, anti-solvent corrosion, high temperature resistant; The UV lamp promptly can send ultraviolet lamp, and UV oil is a kind of adhesive that can solidify under ultraviolet light irradiation.
The present invention uses serigraphy, selects the half tone of different meshes during production for use according to product content.Adjust parameters such as laser imprinting transfer membrane tension, UV lamp power, speed according to ordinary production, cooperate silk-screen printing precoating UV oil can obtain the product that shifts far above the laser imprinting under the conventional art.
The present invention is adapted at the application on the stationery packing, and the application in carton packages such as cigarette, wine, cosmetics, nutriment and high-grade footwear is increasing.Because the UV oil reservoir of screen printed pattern is abundant, third dimension is strong, can improve the class of packing greatly.
