Background technology
The printing of primary colors gold and silver is exactly to be apparent in color and the basically identical printing technology of corresponding metal powder actual color excitation on printed matter after printing.And during the offset press printing gold and silver using at present China ink, because offset press is subject to the restriction of the separated print principle of water oil, in the gold and silver China ink using, the granularity of metal powder need be at 240-250 order, this ultra-fine metal powder is in the carrier oil of ink, can effectively be blended among ink, during printing, guarantee metal powder is not wiped by damping roller, and smoothly the ink spreader by offset press reaches galley.And granularity to be less than 170 object metal powders be to arrive galley by wiping of damping roller.But, this ultra-fine metal powder particle makes the photochromism of itself and the albedo of color be subject to considerable influence just, make that printed matter is a bit darkish in color, burnt hair, substantially lose shown bright beautiful and noble color and luster and the luster effect going out of gold and silver, greatly slackened the product specification of printed matter.
Summary of the invention
The object of the present invention is to provide a kind of printing process that adopts 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 allotment and the processing step that uses conventional offset press to print; Wherein
Ink allotment: select excitation and the satisfactory 130-170 object of brightness metal powder, select printed matter oil polish and the above-mentioned metal powder of transparency >=95%, colourity≤3% to allocate by the weight percent proportioning of 70-80%:20-30%, can obtain the satisfactory offset ink of viscosity;
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, and the flexo resin plate of making is loaded onto;
The 3rd step, according to the pressure criteria of flexo, adjusts the operating pressure of inking roller;
The 4th step, the transfer pressure of adjustment flexo resin plate and blanket;
The 5th step, adjusts the China ink amount that connects that connects ink roller;
The 6th step, alleviates the pressure of distributor rollers, and while guaranteeing inking, gold and silver powder meets the requirement of printing with China ink amount;
The 7th step, adds above-mentioned deployed offset ink in offset press ink fountain, starts offset press normal operation.
The thickness of described flexo resin plate is 1.2-1.5mm, can guarantee not exceed the squeegee pressure interstice coverage of offset press.
For improving the aridity of print product, in ready-mixed oil, can add 5% the dry oil of printing.
As the requirement of the high especially smooth product of needs, described ready-mixed oil can be used 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, utilizing flexo resin plate that the offset ink containing larger particles metal powder is directly printed onto to paper gets on, without changing offset press, by changing the local print principle of offset press, can realize on printed matter 90% with color and the metal sense of Shangdi reduction gold and silver look intrinsic, gold powder can reach the color and luster effect of 24K gold, silver powder has very strong metallic luster, pearl essence of all kinds all can reduce original opaque color and gloss, improved the product specification of printed matter, meanwhile, on printed matter, the oxidation stain speed of color also becomes slower, than the oxidation rate of conventional gold and silver ink print goods, has extended more than 10 times.
The specific embodiment:
Offset press primary colors gold and silver of the present invention printing process, comprises ink allotment and the processing step that uses conventional offset press to print; Wherein
Ink allotment: select as requested excitation and brightness satisfactory 130-170 object bronze or silver powder (or pearl essence of all kinds), select the ready-mixed oil (conventional oil polish) of transparency >=95%, colourity≤3% to allocate by the weight percent proportioning of 70-80%:20-30% with above-mentioned bronze or silver powder (or pearl essence of all kinds), can obtain the satisfactory offset ink of viscosity.If add 5% dry oil in ready-mixed oil, can improve the aridity of printed matter; If when product is had to special high light requirement, can select the good UV gloss oil of quality as ready-mixed oil, then after solid by UV light light, can realize normal printing, and can reach high color purity, high-metal-sense, the primary colors gold and silver effect of high brightness.
Use conventional offset press, do not need to do any change, from monochromatic machine, to six look machines, can normally use.For example, while 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), and four units print four primaries pattern routinely above, and last unit prints spot color gold (spot color silver or other pearly-lustre looks).
