Screen printing ink color

1: Ink company is very important to the procurement of toner, this is a prerequisite for the color of ink, which is the source, only to seize this source, the following work will be able to proceed smoothly. Therefore, the manufacturers of toner must also be rigorously screened. The batch production of toner, the comparison between the previous batch and the next batch of toner is very important, so the inspector must compare the colors very carefully and not behave sloppyly. If it is not strictly tested, then the ink will produce an error with the color of the previous batch of ink. When the ink is used to adjust the color, it is adjusted to the same batch of colors. After the result is transferred, the color will be misaligned. Not right. This is an important factor.

2: The operator cleans the machine table before grinding, after the ink is well proportioned, especially when the black ink is grinded, and then grinds light-colored inks such as white, light yellow and light blue. If it is not cleaned, it will cause pollution of light-colored ink, resulting in color deviation, affecting the accuracy of color correction. So the best way is to separate the light ink and dark ink from the machine to ensure the accuracy of the ink color.
3: In the process of coloring the ink, especially when it is used with small samples, the weight of the ink should be quite accurate. There can be no error. The corresponding ratio should be recorded, and the basis for the next adjustment of the color, such as the green color, should be recorded. Yellow should be added to adjust the shade of blue, and vice versa to add yellow, adjust the color, the size of the mesh is also a great relationship, the higher the mesh under the less ink, the color is shallow, the lower the mesh, The more ink you put down, the darker the color. Therefore, when the ink is printed, the last and the next mesh should be consistent to ensure the consistency of the color. The proportion of ink dilution should be controlled at about 5%, otherwise the color will cause errors.

In short, there are many elements of ink coloring attention. In the actual operation process, some important factors will be discovered. Only after the practice can we realize the mystery. The above is what I experienced in the course of practice. I hope the above points will help the reader and help your company.
