Summary of the invention
The object of the present invention is to provide a kind of printing process adopting existing offset press to realize primary colors gold and silver effect, the method is also applicable to the printing of other pearly-lustre class effects.
For achieving the above object, the present invention can take following technical proposals:
Offset press primary colors gold and silver of the present invention printing process, comprises ink formulation and uses conventional offset machine to carry out the processing step printed; Wherein
Ink formulation: select excitation and brightness satisfactory 130-170 object metal powder, select the printed matter oil polish of transparency >=95%, colourity≤3% and above-mentioned metal powder to allocate by the weight percent proportioning of 70-80%:20-30%, the satisfactory offset ink of viscosity can be obtained;
Print steps:
The first step, makes flexo resin plate by gold or silver-colored spot color version;
Second step, raises the pressure gap of offset press inking roller, is loaded onto by the flexo resin plate made;
3rd step, according to the pressure criteria of flexo, adjusts the operating pressure of inking roller;
4th step, the transfer pressure of adjustment flexo resin plate and blanket;
5th step, the ink that connects that adjustment connects ink roller is measured;
6th step, alleviates the pressure of distributor rollers, and during guarantee inking, gold and silver powder meets the requirement of printing with ink amount;
7th step, adds in offset press ink fountain by above-mentioned deployed offset ink, starts offset press and normally works.
The thickness of described flexo resin plate is 1.2-1.5mm, can ensure the squeegee pressure interstice coverage not exceeding offset press.
For improving the aridity of print product, the dry oil of printing of 5% can be added in ready-mixed oil.
As needed the requirement of high especially smooth product, described ready-mixed oil can use high viscosity UV oil polish.
The invention has the advantages that and use conventional offset press, particle size range is allocated at 130-170 object metal powder (or other pearl essences) and high viscosity ready-mixed oil, utilize flexo resin plate that the offset ink containing larger particles metal powder is directly printed onto paper to get on, without the need to changing offset press, by changing the local print principle of offset press, 90% can be realized on printed matter with Shangdi reduction gold and silver look intrinsic color and metal sense, gold powder can reach the color and luster effect of 24K gold, silver powder has metallic luster strongly, assorted pearl essence all can reduce original opaque color and gloss, improve the product specification of printed matter, meanwhile, on printed matter, the oxidation stain speed of color also becomes comparatively slow, extends more than 10 times than the oxidation rate of conventional gold and silver ink print goods.
Detailed description of the invention:
Offset press primary colors gold and silver of the present invention printing process, comprises ink formulation and uses conventional offset machine to carry out the processing step printed; Wherein
Ink formulation: select excitation and brightness satisfactory 130-170 object bronze or silver powder (or assorted pearl essence) as requested, select the ready-mixed oil of transparency >=95%, colourity≤3% (conventional oil polish) to allocate by the weight percent proportioning of 70-80%:20-30% with above-mentioned bronze or silver powder (or assorted pearl essence), the satisfactory offset ink of viscosity can be obtained.If add the dry oil of 5% in ready-mixed oil, then can improve the aridity of printed matter; If when having a special high light requirement to product, the good UV gloss oil of quality can be selected as ready-mixed oil, more solid by UV light light after, normal printing can be realized, and high color purity, high-metal-sense can be reached, the primary colors gold and silver effect of high brightness.
Use conventional offset press, do not need to do any change, can normally use to six look machines from monochromatic machine.Such as, when using multicolored offset press operation, the product of printing is that four primaries adds a spot color gold (spot color silver or other pearly-lustre looks), then four units print four primaries pattern routinely above, last unit print spot color gold (spot color silver or other pearly-lustre looks).
The print steps of spot color gold (spot color silver or other pearly-lustre looks) is:
