亚克力丝网印刷油墨的调配技巧Acrylic ink deployment skills9-21. toning. With ink, ink consumption should be first calculated for each color print, the deployment of appropriate amount of ink. Especially for two liquid reactive inks, the ink rate shall be calculated according to the curing speed and printing speed.To get the right color, the ink should be carried out under steady natural light, while not counting the colors and observing the effects of the illusion. When the fresh ink is arranged, the dark ink should be gradually approached. It should not be added too much at once, and then be repaired with a large amount of light colored ink. At the same time should try to reduce the mixing hue, hue, the greater the gray scale.It should also pay attention to color changes before and after drying, such as light absorbing substrate of a large quantity of ink on the ink dry wet, often pale; foaming ink dry and the global state phase difference is larger; the ceramic ink color is changed after firing; white ink with high temperature yellow etc.. The law of color change requires the printer to accumulate experience and samples in practice and make their own color codes.Screen printing ink (ink) color deployment is a process that can not be neglected in the process of silk screen printing. The basic principleand basic principle of the deployment of the subtractive method cannotdo without the shade of the colorand color.A hue of a primary color in which the color of any primary color is equally mixed. The three color from the color view, called color (or second colors), such as yellow, green two color mixed to form green isthe color. The color and color mixed to produce hue called complex color (or third colors). Tricolor ink mixture of color and color as shown in figure 3-60. Figure 3-60 tricolor ink mixture of color, color.2. ink toning method. The so-called color matching is more than two colors, or in addition to the main color palette, and then use a small amount of color adjacent to form a combination of colors. The use ofcolor ink before deployment, the color on the color of a single need preparation, correctly distinguish the original (or original) color isthe color, color, or color. If the color, color, need to distinguish the main color and secondary color ratio. Secondly, must be based on the original note of the tone, small sample debugging, and compared to the original, color, color difference or equal, can be a large number of deployment, and the time is short, the amount of appropriate. Tune too little, resulting in downtime, ink hue is different, affecting thenormal production; too much will cause unnecessary waste. Inking is usually carried out where the light is steady or the light is not direct.Screen printing ink palette should pay attention to three points: A. with ink should be as little as possible with different colors of ink,the less the kind of ink, mixing effect better. B. uses "deep to shallow" principle, regardless of the preparation of light or bright colored ink, when the hue closeto the model, be careful. Different manufacturers of ink, it is best not to mix calls, as far as possible the same manufacturers different color ink color, otherwise it will produce color unevenness phenomenon, appear condensed so that the ink scrap will be serious. C. some screen printing inks are dried by drying. Light colored is drier than dry, darker and darker after drying. In addition, the ink tone in theprinting dry before and after drying is different, is easy to ignore the problem. Generally speaking,Through natural drying (solvent ink), the substrate is plastic, metal, paper, glass, color will not change; but if the ceramic pigment, because the oxidized after color, can rely on the experience to thecolor matching. As for the silk screen ink which is dried by thermosetting and light solid, the color changes in the shade, as mentioned above. When inking is large, you can use an inking machine to finish toning in a short time. Oil ink mixed in different proportions, with a lot of color ink, such as table 3-15 lists.The ink color color color ratio formula examples synthesis ofmagenta yellow green 050500: 1: 500501: 0: 1 1 green blue purple 5050501: 1: 1: 3: 0 black 257501 deep yellow 025750: 1: 3: 1: 0 752503 green orange 080200: 4: 1: 1: 1 10025254 green apple red Brown 25251001: 1: 4 greenThe deployment of light ink is generally dominated by white ink,with appropriate color ink. Such as light blue, with white ink, slightly blue (cyan); light red, with white ink, slightly red; gray, with white ink, slightly gray, with black; white ink, a little silver slurry, plus black ink trace. Preparation oflight colored silk screen printing ink (printing material), aslittle as possible to add white ink, because white ink activated, easyto make other colors change color phenomenon.Screen printing workers to tune the ink, we must do: A. understandthe various specifications of ink and performance; make the matching ink for production needs. B. is the master of basic knowledge in color, ink in it. C. analysis of printing color and process technology, to find out the color sequence of multi color, so as to avoid the wrong color sequence, mixed color and color change. D. adjust ink, also payattention to the brightness of the ink color, requiring large brightness as far as possible with the primary colors to deploy, otherwise easy to make up the ink "gray", reducing the original color brightness. 3. adjustment of ink printability. Usually the screen printing ink factory, its viscosity is slightly larger, users should according to the characteristics of the surface tension of printed image, the screen mesh, printing speed, workshop temperature, substrate and ink performance,with a suitable solvent, diluent, surfactant and viscosity, the ink viscosity, surface tension, liquidity and drying velocity of comprehensive adjustment. Such as screen printing lines and outlets,should make the ink flow slightly small, drying speed is slower; coarse screen printing, the viscosity should be slightly larger, drying speed slightly faster; high speed printing, liquidity is slightly big, drying speed slightly faster; the workshop temperature is high, the drying should be slightly slow, slightly larger viscosity the surface tension of the substrate; hours, the surface tension of the ink should be smaller; the printing surface of ink absorption, fluidity and surface tension of the ink can be large, drying speed isslow. Adaptive regulatory techniques also depend on practicalexperience.。
