Detection of coloring power of silicone ink

Jul 22, 2021

The detection of ink coloring power is to use white ink as reference color sample, and judge the strength of a certain ink through its influence on white ink. The detection of color power is to take part in the ink to be tested and standard color ink in a small beaker, mix them evenly and then print the plate, and then compare and judge the strength of the ink according to the standard color sample. The details are as follows:

In a small beaker, take 10g of the ink to be tested and 100g of the standard white ink, mix them evenly, and then print the plate with the color developing wheel. Compare the color sample with the standard ink color card provided by the supplier. If the ink color is light, it indicates that the ink color is weak. If the ink color is deep, it indicates that the ink color is strong. If the ink color is basically common, it indicates that the ink color is qualified.

In addition, by adding the ink to be tested or regulating the component of white ink to detect the strength of color change. If the ink color is too light, the amount of the ink to be tested can be appropriately added. For example, add 2G of the ink to be tested in a small beaker, mix it evenly, and then use the color developing wheel to make the color sample. If it is the same as the standard color sample, then calculate according to (10 + 2) ∶ 100 = 10 ∶ x, and then x = 100 can be obtained × 10 △ 12 = 83.3 (g), indicating that the inking power of this color ink is only 83.3% of that of the standard color ink, which can also be said to be 16.7g weak.
