Description
The present invention relates to antiforge laser holographic trade mark, image printing technology, more clearly say so the transfer printing of laser hologram image is used for the false proof of certificate or trade mark etc. on matrixes such as paper, wood or plastics or be used to print, the reprinting method for laser holography of the decoration of advertisement, lamp decoration etc.
The reprinting method for laser holography of domestic present employing is that laser hologram picture bottom is coated with adhesive sticker, directly sticks on paper, wood, plastics or other matrix, decoratees or false proof purpose to reach.Its manufacturing process is as follows: mold pressing makes it to become holographic picture with holographic picture on the film that is made of PET plastic film layers and metallized film layer earlier, below the metallized film layer, coat transparent non-setting adhesive then, at last holographic picture is sticked on the matrix that needs to paste.This method is pasted not strongly, and easily tears.Can not be unified with traditional printed patterns, effectively, combine harmoniously.
The external reprinting method for laser holography that adopts at present, be that mold pressing becomes holographic large stretch of with holographic picture on the transfer film of forming with PET plastic film layers, separation layer and aluminium coated, this simultaneously coats heat-sensitive glue at aluminium coated then, at last with the holographic picture thermoprint on matrix, the PET plastic sheeting is torn, many holographic pictures unit in holographic large stretch of upward mold pressing here, and is spaced from each other at a certain interval.A holographic distinguishing mark hot stamping process usefulness in also independent mold pressing in each holographic picture unit.Therefore, upward only some is used for the embossed holographic image to holographic sheet, and effective rate of utilization is low.During thermoprint, carry out with special transfer interpreter.Have the photoelectricity detent mechanism on the transfer interpreter.Just pause once along the directions X independent pattern that whenever advances with the packaging material of traditional printing technology printing or other printed matter.Then carry from the holographic picture of strip that holographic large stretch of upward cutting is got off along the Y direction.Independent pattern is when certain position pauses, the photoelectricity detent mechanism just detects the holographic distinguishing mark in the holographic picture unit, then special transfer interpreter just this holographic picture unit accurately thermoprint on the fixed position of the independent pattern of packaging material or other printed matter.This method on matrix, is integral the holographic picture thermoprint with matrix, links firmly can not tear.Its location is also accurate.It combines traditional printing technology and advanced hologram transfer technology, and composition is unified, attractive in appearance.But its production efficiency is low, and the cost height can only be applied on the packing, trade mark, decoration of expensive goods.
Purpose of the present invention is to overcome above-mentioned shortcoming and defect, provide a kind of must Special Equipment, must accurately not locate, the production efficiency height, production cost is low, thereby can be applied to a large amount of high, medium and low shelves products; Link firmly with matrix, can not tear, traditional printed patterns and advanced holographic picture organic unity ground are combined, the reprinting method for laser holography of not only magnificent attractive in appearance but also false proof anti-vacation.
In order to achieve the above object, the holographic picture that reprinting method for laser holography of the present invention is made up of with interference fringe mold pressing on the transfer film of forming with PET plastic film layers, separation layer and aluminium coated, make it to become holographic large stretch of mould pressing process, this simultaneously is coated with the coating technique of heat-sensitive glue at holographic large stretch of aluminium coated, scribble the holographic large stretch of hot stamping process of holographic picture thermoprint on matrixes such as paper, wood or plastics of heat-sensitive glue in certain pressure and following of temperature, technologies such as the PET plastic sheeting of tearing are formed.Heat-sensitive glue gold stampingly gets final product with glue with common, and separation layer then is transparent soap class.Hot stamping process is to carry out on gilding press in common printing, and blocking point is 120-170 ℃, and pressure of hot stamping is 1.5-2.2kg/cm
2, the flatness of the thermoprint head of gilding press is 30-50 μ m, the thickness of the PET plastic film layers of the transfer film of use is 25 ± 0.05 μ m.The maximum linear dimension of the holographic picture unit on the holographic sheet is less than the smallest linear dimension of effective thermoprint area on the thermoprint plane of thermoprint head.Hot stamping process of the present invention not only need not be special transfer interpreter, and without the photoelectricity detent mechanism, only get final product with gilding press with common printing.This has just reduced investment cost, has reduced production cost, has improved production efficiency, and helps popularization of the present invention.120-170 ℃ blocking point can be avoided scalding holographic large stretch of holographic picture, scorch heat-sensitive glue, can improve thermoprint speed again.1.5-2.2kg/cm
2Pressure of hot stamping both can scald real holographic picture, ensure the quality of products, can raise the efficiency again, effect is best.The flatness of the thermoprint head of gilding press is best with 30-50 μ m, can avoid local virtual pressure empty boiling hot, can reduce processing charges again.For well, cross and thinly then easily scalded or scald broken by the conduction of blocked up obstruction thermoprint heat with 25 ± 0.05 μ m for the thickness of PET plastic film layers.The maximum linear dimension of holographic large stretch of holographic picture unit is less than the smallest linear dimension of effective thermoprint area on the thermoprint plane of thermoprint head, can guarantee each thermoprint all can have complete holographic picture by thermoprint on matrix.This is as making handkerchief with figured cloth.As long as the unit pattern size of figured cloth is enough little, and the size of handkerchief is enough big, cuts out in any case, all complete pattern unit can be arranged on the handkerchief.
Holographic large stretch of whole holographic picture that mould pressing process of the present invention is molded into is made of continuously the holographic picture units in two dimensions.The holographic picture unit that holographic large stretch of upward mold pressing in past is spaced from each other, and has holographic distinguishing mark, has both wasted the effective area of holographic sheet, has improved cost, accurately locatees by means of the photoelectricity detent mechanism again, has reduced production efficiency.Of the present invention holographic large stretch of as figured cloth, thermoprint gets final product arbitrarily.Certainly, whenever advancing an independent pattern with the packaging material of traditional printing technology printing or other printed matter along directions X still will be by normal requirement location.
Hot stamping process thermoprint of the present invention be not a holographic picture, but a part of holographic picture on the holographic sheet is as a slice figured cloth of cutting out.
Task of the present invention comes to this and finishes.
The invention provides the common printed gilding press of using of a kind of use, not wholesale investment separately, must the photoelectricity detent mechanism, production cost is low, the production efficiency height can be extended to a large amount of high, medium and low shelves products, links firmly with matrix, be connected as a single entity the reprinting method for laser holography that traditional printing technology and advanced laser holography are organically combined.Its production cost is reduced to 30-55% in the past, and its production efficiency has improved 1-2.5 doubly.The present invention can large-scale popularization be applied to the anti-personation of certificate or trade mark or be used for printing, the decoration of advertisement, lamp decoration etc.
