1. Toning When performing ink color matching, one must pay attention to the effect of the light source on the color of the ink. Generally, color matching should be carried out under natural light, and the color color is more accurate. In the color matching under the artificial light source, it is necessary to select a light source with better color rendering, and the coloring effect of the incandescent lamp is worse. When blending inks, choose the color that is closest to the color of the color, and then add a small amount of other colors to get the color you want. Try to avoid mixing with multi-color inks. Because the more ink colors used in the blending, the higher the gray level of the mixed color, the darker the color, and the easier the ink blending. In the specific ink distribution, the hue of the color matching should be roughly determined, the corresponding ink should be selected, and then the auxiliary ink should be gradually added. When adding dark ink, pay attention to slowly add it. Don't add too much at once, otherwise it will be easy to cause waste and make the deployment repeated many times.

 

2. Adjustment of printing performance During printing, due to many factors such as substrate, environmental conditions, mesh size, etc., many inks can not meet the requirements of use without being formulated. Therefore, the printing performance should be properly used before use. Provisioning. It is generally mainly to improve the printing performance by adding an auxiliary agent. If the mesh size is higher and the drying speed should be slower, a small amount of dry agent can be added. For coarse mesh printing, the viscosity should be slightly larger, and the drying speed should be slightly faster, then an appropriate amount of drier should be added. When adding the auxiliary agent for mixing, be sure to stir evenly, and the amount should be controlled properly, otherwise the effect may be counterproductive.
