Coating knowledge: application scope and precautions of fluorescent ink

Core tip: fluorescent ink is suitable for paper and vinyl film printing Because the inorganic fluorescent material is made of crystal, if the pressure is too large, the crystal will be broken, so that the luminescent brightness will be reduced, so generally, relief printing is not used, which is very suitable for screen printing and gravure printing The rheological properties of most fluorescent inks are plastic like flow with small viscosity, which determines that the printing process is very different from that of ordinary inks In gravure printing and screen printing, in addition to its viscosity, connection material, dryness and other characteristics, we should also pay attention to the adjustment of the printing pressure, so as not to make the printing pressure too large and affect the printing effect Screen printing in progress Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: fluorescent ink is suitable for paper and vinyl film printing Because the inorganic fluorescent material is made of crystal, if the pressure is too large, the crystal will be broken, so that the luminescent brightness will be reduced, so generally, relief printing is not used, which is very suitable for screen printing and gravure printing The rheological properties of most fluorescent inks are plastic like flow with small viscosity, which determines that the printing process is very different from that of ordinary inks In gravure printing and screen printing, in addition to its viscosity, connection material, dryness and other characteristics, we should also pay attention to the adjustment of the printing pressure, so as not to make the printing pressure too large and affect the printing effect In screen printing, we should pay attention to the following points: (1) fluorescent ink is suitable for screen printing under 200 mesh; (2) when the amount of ink is 50-60g / ㎡, its color development and light resistance are ideal; (3) when the substrate is transparent, white ink should be printed once, which can improve the fluorescent effect Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
