济南画册印刷厂家:金银油墨印刷怎么样

来源:http://www.jindingyinshua.com   日期:2019-09-02

  很多客户为了追求外观华美,会选用银墨和金墨印刷,但在设计过程中应依据艺术纸的特性及印刷工艺,合理设计版面,既要做到美观大方,又要充沛思索到金、银墨的特性和印刷工艺请求,尽量防止不应发作的印刷毛病。金银墨是用金粉或银粉(普通为铜、铝粉或铜、铝薄片)颗粒替代颜料粒子,产生高汇集状态的金银色密度的油墨。金银墨印刷的最大特性,就是在印刷之后能表现出特有的金银粉末的悬浮性和成色性,在保管中可保证质量的稳定,不变色。金银墨印刷要依据艺术纸的特性来选用,普通来说,在实地局部或者色块上运用金银墨,而关于非常细小的阴文、阳文或层次过渡则最好不要设计成金色或者银色。

  Many customers will choose silver and gold ink printing in order to pursue beautiful appearance, but in the process of design, we should design the layout rationally according to the characteristics of art paper and printing process, not only to be beautiful and generous, but also to fully consider the characteristics of gold and silver ink and printing process requirements, so as to prevent printing defects that should not occur as far as possible. Gold and silver ink is an ink with high concentration of gold and silver by replacing pigment particles with gold or silver particles (usually copper, aluminium powder or copper, aluminium thin film). The greatest characteristic of gold and silver ink printing is that it can show the suspension and color formation of gold and silver powders after printing. It can ensure the stability of quality and color stability in storage. Gold and silver ink printing should be selected according to the characteristics of art paper. Generally speaking, gold and silver ink should be used on the local or color block in the field, while it is better not to design into gold or silver for very small script, positive script or level transition.
  在制版设计过程中要思索到金银墨的色序布置,以保证金属色泽。还要思索金银墨印刷对艺术纸的请求。假如艺术纸对油墨的吸收性很强,连结料很快被吸收掉,油墨中的金属颜料会浮在艺术纸外表,失去光泽,附着不结实,以至会零落。而酸性较强的艺术纸,易与金属粉发作化学反响,致使金属颜料变色,失去光泽。在艺术纸上印刷金银墨时要先铺底色墨,比方印刷银色油墨时先铺一层淡淡的白墨,这样既能够进步银墨层的光泽度,同时还可以增强银墨在纸张上的附着力。有些产品在印刷金银墨之后,还应该思索UV上光或水性上光,或者覆膜,以避免金属颜料氧化变色或者零落。

  In the process of plate-making design, we should consider the color sequence arrangement of gold and silver inks to ensure the metallic color. Also think about the request of gold and silver ink printing for art paper. If the art paper absorbs ink very strongly, the linking material will be absorbed quickly, and the metallic pigments in the ink will float on the surface of the art paper, lose lustre, not firm enough to adhere, and even will fall off. The strong acidic art paper is easy to react chemically with metal powder, resulting in discoloration of metal pigments and loss of luster. When printing gold and silver ink on art paper, we should first lay the base color ink, for example, when printing silver ink, we should first lay a light white ink, which can not only improve the gloss of silver ink layer, but also enhance the adhesion of silver ink on paper. After printing gold and silver inks, some products should also consider UV or water-based polishing, or film coating, in order to avoid metal pigments oxidative discoloration or scattering.
  金银墨印刷请求特地的印刷处置工艺,金银墨的耐久性普通比颜料粒子差,但是能够运用印刷涂层或上光层停止维护。用粉状的金属颜料制的油墨,在印刷机上都有变稠(厚)现象,而用湿的金银浆状颜料配置的油墨就比拟好。在印刷中,金银墨具有低粘度的特性,适于在墨辊间传送,使印刷过程比拟洁净。对承印物来说,粗糙的艺术纸会阻止细小的金银墨颗粒在纸张外表构成金属箔而降低了金银墨的印刷效果。此外,运用金银墨印刷的作用主要是突出其金属特征,由于其他油墨的不透明性会影响其金属效果,因而,在布置印刷色序上,普通都请求将金银墨放在最后印刷。由于金银墨的不透明性会招致补偿过多的油墨,只要经过运用较多的油墨来完成理想的金属效果,但这会招致油墨呈现不均衡的现象,给润版系统带来过多的担负,惹起糊版和起脏等毛病。避免这些毛病的最好方法是在一个颜色较浅的图像上添加油墨,使其恰恰掩盖住图像。然后,增加墨量,并调理供水量,使其稍稍高于最小值,从而防止非图文局部着墨。为使金银墨具有良好的印刷适性,选用的调墨油(调金油和调银油)必需保证有足够的粘度、良好的化学稳定性,要有较好的透明性,枯燥固差性能优秀,要保证调墨油与金银粉能平均地混合,并能进步金银粉的成色性能,使金属光泽和着色才能更强。
  Gold and silver ink printing requires special printing process. The durability of gold and silver ink is generally worse than that of pigment particles, but it can be maintained by using printing coating or polishing layer. Inks made of powdered metal pigments tend to thicken (thicker) on the printing press, whereas inks made with wet gold and silver paste pigments are better. In printing, gold and silver inks have the characteristics of low viscosity, suitable for transmission between ink rollers, making the printing process comparatively clean. For prints, rough art paper prevents fine gold and silver ink particles from forming metal foil on the surface of the paper and reduces the printing effect of gold and silver ink. In addition, the use of gold and silver ink printing is mainly to highlight its metal characteristics, because the opacity of other inks will affect its metal effect, so in the layout of printing color sequence, the general request for gold and silver ink in the final printing. As the opacity of gold and silver ink will lead to excessive compensation of ink, as long as more ink is used to achieve the ideal metal effect, but this will lead to ink imbalance, bring too much burden to the printing system, causing paste and dirty and other problems. The best way to avoid these problems is to add ink to a lighter color image so that it just covers up the image. Then, increase the amount of ink and adjust the water supply to make it slightly higher than the minimum value, so as to prevent non-graphic local ink. In order to make the gold and silver inks have good printing adaptability, the selected toner oil (gold and silver toner) must ensure adequate viscosity, good chemical stability, good transparency, good dryness and poor solidity, ensure that the toner oil and gold and silver powder can be mixed equally, and can improve the color performance of gold and silver powder. Metal luster and colouring can be stronger.
