Description
Technical Field
The invention belongs to the technical field of printing, and relates to medium paper, in particular to a printing process of laser silver cardboard imitated medium paper.
Background
When in printing, the medium paper is used as a base material to print various colors, not only has the color saturation of the white cardboard, but also has the brightness and laser effect of transferring the cardboard, and can show elegant artistic aesthetic feeling with low tone on a printed matter. But the process is complex, and the cost is compared with that of the common laser paperHigh. Lithographic offset printing uses pre-coated photosensitive plates (PS plates) and oily inks. Conventional PS plates are generally divided into three layers: the lowest layer is a metal plate base, usually made of metal aluminum; the intermediate layer being an oxide of aluminium (Al 2 O 3 ) The method comprises the steps of carrying out a first treatment on the surface of the The uppermost layer is a pre-coated non-silver salt photosensitive resin (such as diazonium salts).
In order to reduce the cost, not to influence the appearance of the product, and to expand the use of the laser silver paperboard, the invention uses a layering printing process to print white ink and ink with special laser effect on the surface of the laser silver paperboard in a sequential offset way, so that the laser paper can obtain the surface effect of the medium paper.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to disclose a printing process of laser silver card paper imitated media paper.
The specific technical scheme is as follows:
a printing process of laser silver cardboard imitation medium paper comprises the following steps:
A. before printing, processing graphic and text information, designing a white edition file, arranging a sequentially graded multi-level transition screen in the white edition file, and manufacturing a white edition according to the image file;
B. the offset press is well debugged, white ink is offset on the surface of a printing stock, the ink coverage at the sparse positions of the dots of the white plate is small, the brightness of laser silver card paper can be penetrated out, and the optical column visual effect of medium paper is obtained;
C. gravure printing and solidifying ink on the surface of the paper after the paper is dried;
D. cooling and collecting paper, and the surface of the printing stock has whiteness and laser effect of medium paper.
In a preferred embodiment of the present invention, the coverage rate of the transition net in step a is 50-80%, preferably 60-70%.
In a preferred embodiment of the present invention, the white plate in the step a is a PS plate.
In a preferred embodiment of the present invention, the printing stock in the step B is a laser silver cardboard.
In a preferred embodiment of the present invention, the surface tension of the offset white ink in step B is less than 30mN/m, preferably 28mN/m. The ink with a lower surface tension is chosen so that the ink dried after offset printing is more pronounced for the image formed by the transition dots.
Furthermore, the offset white ink is UV ink, has good curing effect, is not easy to fall off and has no environmental pollution.
In a preferred embodiment of the present invention, the ink in the step C is UV laser ink.
