Luminous ink, printing paste preparation

1, according to printing requirements, select the appropriate size of luminous powder.

     2, neutral or weak acid with a transparent resin, low transparency will affect the luminous effect;

     3, add a ratio of 20% -60% (by weight), according to experience 45% -50% is relatively good;

     4, coating thickness should be greater than 100um ,120-150um (80 mesh, such as India with about twice the thickness) will be better;

     5, mixed methods: the proposed first ready, luminous powder on the container, add equal amount of resin mix (to avoid using metal utensils, mixing stick, otherwise it will reduce the luminous effect), so that luminous powder to fully wet, remove luminous powder particle surface of the air, so as not to affect the dispersion, the other should be noted that elimination of agglomeration. For color mixing and processing aids can be simultaneously (to avoid the use of heavy metal-containing compounds and color additives). Mix well, then pour in proportion to the prepared resin mix.

     6, such as using water-based slurry or ink, Long-lasting luminous powder to be handled by a special micro-capsule package, whether processed, please consult in advance;

     7, was printed items such as color is not white or light-colored, white should be hit, can increase the luminous intensity;

     8, because a larger proportion of luminous powder, easy to precipitate, to now with the existing as well, and stir constantly in use; luminous ink, such as non-cash distribution, according to the printing speed should be increased to adjust the ink viscosity with thinner;

     9, the above recommendations for reference, according to the characteristics of their product and process again to deepen, refine.
