Description
Technical field
The present invention relates to chromatography field, and in particular to the positive and negative overprinting process using composite membrane as base material.
Background technology
Molding laser printing is a high-tech typography, integrates false proof and aesthetic feeling because laser graphic has
Advantage and be widely used in advertisement, illustration and packaging field.The method of prior art laser molding is first to be molded lithographic plate
Version volume is attached in cylindrical mold pressing roll, so as to be inevitably present the seam of molding version；Utilize such molding version and mould
The laser molding product that pressure device is produced, such as oriented polypropylene (OPP) (OPP) film, polyethylene terephthalate
(PET) film and polyvinyl chloride (PVC) film and paper etc., the laser graphic being stamped in above them are connect due to molding version
Stitch and version seam be present so that picture and text are discontinuous, the presence of version seam has a strong impact on laser molding product answering in web feed printing equipment
With.When printing figure message, which is printed on version, to be sewed on, spoilage will be produced；At present, some printing factories are using expensive jump seam
The molding version that device is skipped in printing on laser molding product is stitched to avoid the generation of spoilage, but it is very high to jump seam device
Close cooperation is given by molding producer expensive and that needs are special, is difficult in printing industry by the way of seam device is jumped therefore
Promote.
In the prior art, the usage amount of basement membrane is larger, and waste is more serious, while the usage amount of roller also can be more.This
The reduction and the raising of product quality that printing cost will be unfavorable for.And shift the common release agent material that film uses, spray
Aluminium lamination only contacts with mould release, can be effectively peeled off sprayed-on Al layer, but for there is one layer of relatively thick ink layer between the two, then
Being effectively peeled off for printing-ink can not be met；The common aqueous transfer glue water that uses of transfer film, can be by sprayed-on Al layer from release
Peeled away on agent material, but because there is thicker ink layer on sprayed-on Al layer, side can not meet printing ink layer and sprayed-on Al layer simultaneously
From effective transfer on peel ply.Also, plastic flexible package composite membrane picture and text print when be printing in film reverse side, then will printing
Ink surface is compound with hot sealing layer dry type and is made, it is necessary to can only be after dry type is compound again using the pattern of alumite thermoprinting foil thermoprint
Thermoprint causes that alignment can not be positioned with the printed patterns of film reverse side, picture and text are exposed to film after thermoprint on the surface of composite membrane
Surface easily abrades.
The content of the invention
The technical problems to be solved by the invention are that the cost of existing overprinting process is high, and finished product of poor quality, mesh
Be the positive and negative overprinting process using composite membrane as base material is provided, solve the problems, such as the overprinting process using composite membrane as base material.
The present invention is achieved through the following technical solutions：
Positive and negative overprinting process using composite membrane as base material, comprises the following steps：

On, roller is arranged in moulding press, the transfer membrane being cured is subjected to two pairs of rollers molding with the roller in moulding press and pressure roller, will
Multiple spot security pattern in die work version is transferred on transfer membrane；
S5：Transfer membrane is attached in printing paper, with glue spreader in the face gluing of printing paper one, by the printing after gluing
Manufactured transfer membrane is combined with each other by hot-pressing roller during paper walks with S5；
S6：By the transfer membrane surface being combined with each other in S5 with hot-pressing roller through 200-500 angstroms of vacuum aluminum-plating machine vacuum evaporation
The aluminium coated of thickness；
S7：Transfer membrane after composite membrane cuts separation with printing paper, now the multiple spot security pattern on transfer membrane by
The surface of printing paper is transferred to, while the multiple spot security pattern on transfer membrane is still present, and it is above-mentioned compound with peeling off work
Skill can be repeated several times；
S8：Installation chromatography, the printing paper after S7 steps are stripped are sent into printing machine, make the upper figure of printing plate cylinder of printing machine
Case, which accurately covers, to be imprinted on the multiple spot security pattern being transferred in printing paper；
S9：Die cutting qualified ratio, S8 is walked into the slitting paper after printing into finished product.
