Abstract
The invention discloses a kind of gold and silver printing processes, comprise the following steps：Stock plus auxiliary material, plate-making, printing and curing.Present invention process is simple, and not only printing efficiency is high, increases a variety of protective ingredient structures for gold and silver printing layer, substantially prolongs the service life of gold and silver printing layer.
Description
Technical field
The present invention relates to gold and silver print field, more particularly to a kind of gold and silver printing process.
Background technology
At present, currently, the either producer or user, increasingly pay attention to the outer packing of product, market is to each
The high-grade packaging and personalized packaging demand of kind various kinds are also increasing.Under this trend, packages printing field is also continuous
New process, new material are developed, to cater to the demand of packaging market.
The printing of primary colors gold and silver is exactly color and the corresponding metal powder actual color color being apparent in after printing on printed matter
The basically identical printing technology of purity.And use at present offset press printing gold and silver ink when, due to offset press be subject to water oil separation
The limitation of print principle, the granularity of metal powder need to be in 240-250 mesh in the gold and silver ink used, and this ultra-fine metal powder is in ink
Carrier oil in, can effectively be blended among ink, when printing could ensure that metal powder is not wiped by damping roller, and smoothly lead to
The ink spreader for crossing offset press reaches galley.And the metal powder that granularity is less than 170 mesh is can not to be reached by the erasing of damping roller
Galley.But it is exactly that this ultra-fine gold and silver powder particles cause the photochromism of itself and the albedo of color to receive
Larger impact, makes printed matter be a bit darkish in color, burnt hair, lose substantially the bright beautiful and noble color and luster that goes out shown by gold and silver and
Luster effect has slackened the product specification of printed matter significantly.
Such as the Chinese invention patent " printing process of offset press primary colors gold and silver " of patent No. ZL201310509128.6, disclose
A kind of offset press primary colors gold and silver printing process, first with the metal powder below 170 mesh, the printed matter oil polish for selecting transparency high
Offset ink is deployed into proportion with metal powder；Flexo resin plate is made in gold or silver-colored spot color version；Raise offset press inking roller
Pressure gap loads onto flexo resin plate；According to the pressure criteria of flexo, the operating pressure of inking roller is adjusted；Adjust flexo
The transfer pressure of resin plate and blanket；What adjustment connect ink roller connects black amount；Mitigate the pressure of distributor rollers, ensure metal powder during inking
The requirement for meeting printing is measured with ink in end；Deployed offset ink is added in offset press ink fountain, starts the normal work of offset press
Work.The intrinsic color of gold and silver color and metal sense.
Above-mentioned patent is disadvantageous in that：It is only used for improving the intrinsic color of gold and silver color and metal sense, improves brush product
Product specification, but the stability of gold and silver printed-layer structure is poor, and does not have any safeguard measure for gold and silver printing layer, makes
The gold and silver printed matter service life that must be produced is short, and for gold and silver printing layer once damaging, corresponding object just becomes waste product, be easy to cause
Substantial amounts of dregs of society, are unfavorable for environmental protection.
The content of the invention
It is an object of the invention to overcome the above problem existing in the prior art, a kind of gold and silver printing process is proposed.This hair
Bright simple for process, not only printing efficiency is high, increases a variety of protective ingredient structures for gold and silver printing layer, substantially prolongs gold and silver printing
The service life of layer.
The present invention is realized using following technical scheme：
A kind of gold and silver printing process, it is characterised in that comprise the following steps successively：
Stock：It chooses UV light-curable inks and metal powder presses 60-65%：The weight percent of 35-40% is allocated, and is printed
Oil,
Add auxiliary material：Auxiliary material is added in into off-set oil, is uniformly mixed, the amount that auxiliary material adds in is to print the 10-15% of oil mass, institute
Stating auxiliary material includes additive, anti-scratch auxiliary agent and binder, the ratio of additive, anti-scratch auxiliary agent and binder in the auxiliary material
For 5-8：2-3：3-5；
Plate-making：Flexo resin plate is made in gold or silver-colored spot color version, the flexible resin plates include base material and elastic ground, the base
Material is arranged at elastic ground in the following, the base material thickness is 0.05-0.2mm, and the thickness of elastic ground is the flexible resin plates
/ 3rd of thickness；
Printing：Using roller screen process press in one layer of printing oil reservoir of surface spray printing of flexo resin plate, roller screen process press
Rotating speed for 400-450 revs/min, the operating temperature of roller screen process press is 25-30 DEG C, and the work of roller screen process press is wet
It spends for 30-40RH%；
Cure：After the printing oil reservoir of spray printing on flexo resin plate is cured by ultraviolet high-pressure mercury lamps, drying device
Finished product is obtained after drying.
The material hardness of the elasticity ground is that Shore Hardness is 30-70 degree.
The parameter of the UV light-curable inks is：
Viscosity：3.0±0.1Pa•s；
Proportion：1.10g/cm3；
