教您如何为金属蚀刻机调配油墨！Teach you how to mix ink for metal etching machine!

　　开印前不仅要准备好要用的油墨，还要根据需要，对其颜色和印刷性能进行调配，以满足印刷的需要。配墨前，应先估算出相应的耗墨量，使调墨量适当。尤其是对二液反应型油墨，应根据其固化速度和印刷速度来估算其调墨量。

　　1.调色 在进行油墨颜色调配时，一是要注意光源对油墨呈色的影响。一般应在自然光下进行配色，颜色呈色就比较准确。而在人工光源下配色，就要选择呈色性比较好的光源，白炽灯的呈色效果就差些。调配油墨时，应选择与所配色最为接近的颜色，然后通过加入少量的其他颜色即可得到所需的颜色。应尽量避免用多色油墨调配。因为调配时所用的油墨色数越多，则混合色的灰度越高，颜色越暗，也使得油墨的调配不易掌握。在具体配墨时，应大致确定所配色的色相，选定相应的油墨，然后再逐渐加入辅墨。在加入深色墨时要注意慢慢加入，不要一次加入过多，否则既容易造成浪费，又使得调配反复多次。

　　2.印刷性能的调节 在印刷时，由于承印物、环境条件、丝网目数等诸多因素，许多油墨不经调配都不能满足使用要求，为此在使用前都要对其印刷性能进行适当的调配。一般主要是通过添加辅助剂的方法来改善其印刷性能。如丝网目数较高，干燥速度应稍慢，则可加入少量的止干剂。而粗网印刷时，粘度应稍大，干燥速度应稍快，则应加入适量的催干剂。在填加辅助剂进行调配时，一定要搅拌均匀，其用量也要控制适当，否则效果可能适得其反。

      Before printing, not only the ink to be used should be prepared, but also the color and printing performance should be adjusted according to the needs to meet the needs of printing. Before inking, the corresponding ink consumption should be estimated to make the inking amount appropriate. Especially for the two-liquid reactive ink, the ink volume should be estimated according to its curing speed and printing speed.

       1. In the process of ink color mixing, the first is to pay attention to the influence of light source on ink color. Generally, color matching should be carried out under natural light, and color rendering is more accurate. Under artificial light source, we should choose the light source with better color rendering, and the color rendering effect of incandescent lamp is worse. When mixing ink, you should choose the color closest to the color you want, and then you can get the desired color by adding a small amount of other colors. Should try to avoid using multi-color ink deployment. Because the ink used in the deployment of the number of colors, the higher the gray level of the mixed color, the darker the color, making ink deployment difficult to master. In the specific ink matching, we should roughly determine the hue of the color matching, select the corresponding ink, and then gradually add the auxiliary ink. When adding dark ink, you should pay attention to adding it slowly, not too much at a time, otherwise it is easy to cause waste, and make the deployment repeated many times.

    2. When adjusting the printing performance, due to many factors such as substrate, environmental conditions, mesh number and so on, many inks can not meet the use requirements without deployment, so the printing performance should be properly deployed before use. Generally, the printing performance is improved by adding auxiliary agent. If the mesh number of the screen is high and the drying speed should be slightly slow, a small amount of anti drying agent can be added. While in coarse screen printing, the viscosity should be a little higher and the drying speed should be a little faster, then a proper amount of drier should be added. When the auxiliary agent is added for mixing, it must be stirred evenly, and its dosage must be controlled properly, otherwise the effect may be counterproductive.
