In the selection of inks, it is best to add the luminous powder to transparent inks. Colored inks can also be added to luminous powders, but the darker the color of the ink, the lower the luminous brightness, and the darker the ink needs to be added. The ratio of luminous powder to enhance the brightness of luminous.
Different printing materials need to use corresponding inks. For example, metal materials need to use special metal inks, and ABS plastic materials need to use ABS special inks so that the luminous ink can be more secure.
In the formulation of the ink, in a 1 kg ink, the glow in the dark powder is 300 g to 1 kg. Within this range, the more the luminous powder content, the higher the brightness, and the less the amount of addition, the uneven dispersion will result, resulting in uneven dispersion. Some products do not glow, or black spots appear when glowing.
Put the luminous powder in the container, add an appropriate amount of ink, and stir with wooden products (you cannot use metal items to stir, chemical reactions will occur). When stirring, you need to pay attention to exhaust the air in ink. The luminous powder and ink are sufficient. After mixing and stirring well, the luminous ink is made.
When screen printing, generally use 80-150 mesh screens for printing. If you have special requirements, you can also choose a finer screen version, but you must pay attention to the size of the luminous powder to ensure that the luminous powder can Pass through to avoid clogging with luminous powder.
