印刷油墨的性质对颜色有什么影响?

济南宣传单页印刷厂家提示大家,印刷品的更终效果和油墨的理化性能密切相关,具体的来说就是油墨的组分决定了油墨的性质:
Jinan Publicity One-page Printer reminds you that the final effect of the printed matter is closely related to the physical and chemical properties of the ink. Specifically, the composition of the ink determines the nature of the ink:
1、连接料的粘度与颜料的含量
1. Viscosity and Pigment Content of Connecting Materials
依据界面化学原理,毛细管浸透速度与液体粘度反相关,即浸透速度随粘度的增加而降低。油墨颜料颗粒间构成的毛细管网络构造是决议印刷品光泽的一个重要方面。在压印霎时,油墨被整体地压入纸张较大的孔隙内;在压印后,衔接料开端从油墨别离,渗入纸张较小的孔隙内。因而,油墨膜毛细管的大小决议着衔接料的别离量。毛细管保存衔接料的作用比印刷压力把衔接料压入纸张孔隙的作用大得多。
According to the principle of interfacial chemistry, the capillary immersion velocity is inversely correlated with the liquid viscosity, that is, the immersion velocity decreases with the increase of the viscosity. The structure of capillary network composed of ink and pigment particles is an important aspect to determine the gloss of printed matter. In imprinting, the ink is pressed into the larger pore of the paper as a whole; after imprinting, the linker begins to separate from the ink and penetrate into the smaller pore of the paper. Therefore, the size of the ink film capillary determines the separation of the binder. The effect of capillary on preserving bonding material is much greater than that of printing pressure on pressing bonding material into paper pore.
2、颜料颗粒的大小及其分散水平
2. Size and Dispersion Level of Pigment Particles

固然墨膜毛细管的作用是构成印刷品光泽的重要要素,但是,分散状态下的颜料颗粒的表观大小更重要,它直接决议墨膜毛细管的状态。

Although the role of ink capillary is an important factor in the gloss of printed matter, the apparent size of pigment particles in the dispersed state is more important, which directly determines the state of ink capillary.
因此,颜料颗粒小,分散良好,有利于构成平滑的墨膜,关于进步印品光泽也是十分有利的。
Therefore, the pigment particles are small and well dispersed, which is conducive to the formation of a smooth ink film. It is also very advantageous to improve the gloss of printing products.
3、干燥时间
3. Drying time
墨膜在纸面疾速枯燥能够减少衔接料渗入纸张孔隙的量,从而进步墨膜的光泽度战争滑度。墨膜的光泽度高就意味着外表的镜面反射水平比拟高,这样人眼在大局部状况下能看到外表反射的白光要比光泽度低的墨膜少得多,使得颜色的饱和度更高。所以光泽度高的印品看起来颜色愈加鲜艳、丰满。专色油墨的印刷墨层大局部是半透明的或不透明的,在选择油墨配方时也要依据实践状况思索到墨层的透光性对专色印刷的影响。
The rapid drying of ink film on paper surface can reduce the amount of linking material penetrating into the paper pore, thus improving the gloss and slippage of ink film. The high gloss of the ink film means that the mirror reflection level of the outer surface is comparatively high, so that the human eye can see the white light reflected by the outer surface in most cases is much less than that of the low gloss ink film, which makes the color saturation higher. So the high gloss print looks more bright and full. The ink layer of spot-color ink is mostly translucent or opaque. When choosing the ink formula, we should also consider the influence of the light transmittance of the ink layer on spot-color printing according to the practical situation.
以上就是为大家分享的印刷专色油墨的印刷色差缘由,产生专色油墨印刷色差的要素很多,但主要有:资料的性能、油墨的性质、印刷条件、印刷品的外表整饰,这些要素都会影响专色印刷过程中的颜色再现。
Above is the reason why we share the printing color difference of spot-color ink. There are many factors that cause the printing color difference of spot-color ink. But the main factors are: the performance of data, the nature of ink, printing conditions, and the appearance decoration of printed matter. These factors will affect the color reproduction in the process of spot-color printing.
