    1.仔细观察色样,特别注意观察被印基材,从基材粗糙与光滑.反射程度来选择油墨. 例如,
    1. Carefully observe the color pattern, pay special attention to the printed substrate, choose the ink from the roughness and smoothness of the substrate. For example,
    油墨印刷在光滑.反光极强的铝板或易拉罐上,选择透明性高的油墨, 将有助于增强油墨
    Ink printing on smooth, highly reflective aluminium sheets or cans, the choice of transparent ink, will help to enhance ink
    的金属光泽.
    Metallic luster.
    2.选择配色所需的油墨时,尽可能避免混合过多油墨.尽量使用接近于标准色及由单一颜
    2. When choosing the ink needed for color matching, avoid mixing too much ink as possible. Use near standard color and single color as far as possible.
    料制成的油墨.配色使用色墨越多.离标准色越远,则亮度越差, 混合出来的颜色哑光程度
    Inks made of materials. The more color inks are used for color matching. The farther away from the standard color, the worse the brightness and the matte degree of the mixed color.
    越高.不可能借配色来调制原色.
    The higher the color is, it is impossible to modulate the original color.
    3.要特别注意油墨着色力.如果所选用油墨浓度不够高,不论怎样拼配,也无法达到标准颜
    3. Particular attention should be paid to the dyeing power of the ink. If the concentration of the selected ink is not high enough, no matter how to match, it will not reach the standard color.
    色浓度.
    Color concentration.
    4.需要加入白.黑墨时,应特别注意所加入的分量及称量的准确性.在所有油墨中,黑墨的遮
    4. When white and black ink is needed, special attention should be paid to the weight added and the accuracy of weighing. In all inks, black ink is covered.
    盖力特强,加入过多,不但会冲淡颜色,同时也会阻止底材反光程度.不过对于印刷凹凸不平
    Gelly is very strong. Too many additions will not only dilute the color, but also prevent the reflectivity of the substrate. However, for printing bumps and bumps.
    基材尼龙布.纸板时,为了保证印品外观,最好印刷一层作为底色的白色.由于黑墨的着色力
    Base material nylon cloth. In order to ensure the appearance of printed products, it is better to print a layer of white as the background color. Because of the dyeing power of black ink.
    特强,稍不慎加入过多,就需要加入相当多其它色墨来调整颜色,造成浪费.因此要特别注意.
    Super strong, slightly accidentally add too much, you need to add a considerable number of other color ink to adjust the color, resulting in waste. Therefore, special attention should be paid.
    5.制作淡色油墨时,应从墨膜透光程度判断其应加入多少白墨或调墨油(冲淡剂)进行调色.
    5. When making light ink, we should judge how much white ink or toner (diluent) should be added to tone the ink according to the transmittance of the ink film.
    绝对不允许把溶剂用于冲淡颜色.溶剂加入过多,不但会影响印刷性能,而且会破坏油墨结
    Solvents must not be used to dilute colours. Excessive solvent addition will not only affect the printing performance, but also destroy the ink knot.
    构,造成颜料与树脂油分离,出现常常或者大大地降低油墨光泽.

    It causes the separation of pigment from resin oil, which often or greatly reduces the luster of ink.

    6.提高印刷墨膜光泽方法 1.在颜色浓度允许范围内加入适量调墨油. 2.印刷墨膜表面涂
    6. Ways to Improve the Gloss of Printing Ink Film 1. Adding appropriate amount of toner to the allowable range of color concentration. 2. Printing Ink Film Surface Coating
    一层罩光油或者调墨油. 3.增加油墨透明度,如选用高透明度的高光油墨或者加入适量调
    A coat of varnish or toner. 3. Increase the transparency of ink, such as using high-transparency high-light ink or adding appropriate toner.
    墨油,利用光滑.把射力强基材的反射增加光泽. 4.防止基材表面吸附,合理改进基材印刷面
    Ink, make use of smoothness. Increase the reflective gloss of the strong base material. 4. Prevent the adsorbing of the base material surface and improve the printing surface of the base material reasonably.
    的光滑程度. 5.注意印刷环境的温度.湿度.参湿度高.温度低的情况下,进行塑料凹版印刷时,
    Smoothness. 5. Pay attention to the temperature, humidity, high humidity of the printing environment. When the temperature is low, plastic intaglio printing should be carried out.
    由于溶剂挥发速度快 (通常1分钟墨膜表面就已干燥) , 吸收墨膜周围热量而造成该处空气
    Because the solvent evaporates quickly (usually the surface of the ink film dries in 1 minute), it absorbs the heat around the ink film and causes the air there.
    中水蒸汽急剧冷凝,使印刷墨膜表面形成雾气,使墨层失去光泽. 在格梅雨季节中,要特别注
    In the season of Gemeiyu, special attention should be paid to the formation of mist on the surface of printing ink film and the loss of luster caused by the rapid condensation of medium water vapor.
    意控制印刷环境的温度与湿度,保证良好的印刷效果. 7.荧光油墨不能与大量非荧光油墨进
    Intentionally control the temperature and humidity of printing environment to ensure good printing effect. 7. Fluorescent ink can not enter with a large number of non-fluorescent ink.
    行混合配色,否则会失去油墨荧光效果.
    Mixed color matching, otherwise the ink will lose the fluorescent effect.
    张力太大时,丝印时,刮油墨时较费力,易将网版膜撕破,如果张力过小,则印刷时的回弹力小,
    When the tension is too high, scraping ink is more laborious and easy to tear the screen film. If the tension is too small, the resilience of printing is small.
    达不到应有的回弹效果,易糊线条.
    Can not achieve the desired rebound effect, easy to paste lines.
