Technical field

The present invention relates to the printing technologies more particularly to a kind of not frangible dedicated 3D raster print product of cigarette packaging And preparation method thereof.

Background technique

At present in the 3D printing technology of print field, there are two types of 3D printing technologies, and one is in printing on substrates 3D grid Change image, then carries out mount with raster film, obtain the dynamic image of 3D stereo-picture or multi-picture；Another kind is in light UV is carried out on grid film and prints 3D rasterized images, obtains 3D rendering.But traditional raster film 3D printing product, all from It does not open using raster film as substrate.And raster film is as a kind of plastic product, in Packaging Printing Product using upper, there is Following defect: first, do not have the feature of environmental protection, plastics manufacture needs to consume a large amount of social resources, while degradability is poor；Second, it answers With at high cost, film is as packaging material, and due to being influenced by many processing technology factors, usually entire packaging is all used Raster film, less carry out topical application all use mount mode, but local mount mode instead can shadow even if topical application The globality and aesthetics for arriving packaging external appearance are rung, so do not use generally, and entirety undoubtedly will increase packaging using raster film Overall cost；Third, packaging applications are poor, are mainly shown as that the processing forming of plastic film is poor, and can not carry out table Face post-processing.Therefore, company develops a kind of 3D direct printing process, the material containing plastic grating is not used, using UV gloss oil In directly printing molding on printable fabric.

In this technology, need to use UV gloss oil, but it is very hard after general UV gloss oil film forming, and flexibility is very poor, holds very much Easily there are paper products and folds quick-fried color, damaged phenomenon.And in order to solve the problems, such as that printed matter is fragile, need printing house to paper , the associated materials such as ink and cross cutting and technique propose quite high requirement, this will lead to the increase and production efficiency of cost Reduction.Meanwhile it is cigarette packing box, wrapping paper etc. that our company, which needs to use the 3D directly to print technology, general UV gloss oil is not Meet YQ15 cigarette standard.

Summary of the invention

The invention solves the above problem, one kind is provided and not only conforms with YQ15 cigarette standard, and can effectively solve the problem that print Dedicated 3D raster print product of the fragile problem of brush product and preparation method thereof.

The technical solution that the present invention solves the problems, such as is to provide a kind of not frangible dedicated 3D raster print product, successively includes Printing layer, rasterized images layer and light oil reservoir, the light oil reservoir is according to mass parts, including ethoxylated trimethylolpropane 3 third 10-30 parts of olefin(e) acid ester, caprolactone modification 5-15 parts of 40-60 parts of urethane acrylate polymer, acrylic acid esters co-polymer, 1-10 parts of 1,6 hexanediol diacrylate, TPO1-5 parts, 1-3 parts of isooctyl p-dimethylaminobenzoate, polydimethylsiloxanes 0.01-0.5 parts of alkanes surfactant, 0.01-0.5 parts of anionic surfactant, 1-5 parts of PE wax and hydrophobic type gas phase two 0.5-3 parts of silica.

Preferably, the anionic surfactant is neopelex.

Preferably, the light oil reservoir refractive index is not less than 1.5.

Preferably, the thickness of the light oil reservoir is not more than 0.12mm.

Preferably, the thickness of the light oil reservoir is not more than 0.1mm.

It is a further object to provide a kind of preparation methods of not frangible dedicated 3D raster print product, including with Lower step:

A. its rasterizing is handled after design and printing image, then high-accuracy sleeve position is set mark, carries out screening processing, exports offset printing Printing plate；

B. the processing of set position will be carried out according to high-accuracy sleeve position mark after the version of offset printing forme installation school, then carries out high definition print with printing layer Brush and curing process, obtain offset printing printed sheet；

C. raw material is mixed with gloss oil according to above-mentioned mass parts；Obtained gloss oil is coated on 3D grating gravure；

D. the 3D grating gravure after coating gloss oil is pressed together, while curing molding with offset printing printed sheet, is not easy Broken dedicated 3D raster print product.

Preferably, in step a, rasterizing processing is carried out according to the template raster density of 3D printing plate after design and printing image.

Preferably, the template raster density of the 3D printing plate is not less than 280LPI.

Preferably, offset printing forme output accuracy is not less than the screening linear speed of 9600DPI and 800LPI.

Preferably, in step d, when curing molding, minimum solidification energy demand is 47-55j/cm2.

Beneficial effects of the present invention:

1. gloss oil formula provided in the present invention, not only conforms with YQ15 standard, and to solidify obtained 3D raster print product With good flexibility, after 180 ° of doublings three times of arc of φ 6mm, still flawless and peeling phenomenon, not fragile.

2. gloss oil formula provided in the present invention, can make light oil reservoir thickness down to 0.1mm or so, be effectively improved gloss oil The angle of layer arcwall face, and the 3D effect of the light oil reservoir of obtained relatively low thickness can achieve the effect of former 0.22mm thickness.

3. using 3D direct printing process, without using the material containing plastic grating, and the high definition imaging of slim medium is reached Purpose, applicability is wide.
