Fluorescent screen printing ink (below)

Daylight-type fluorescent color can best exert its advantage in the dark environment and contrasting colors, especially on the white surface. For best impact, fluorescent colors should not be used alone. It can be used to highlight a particularly important point. It can also be set off with 50% gray or the opposite color. Half-tone printing with fluorescent ink is not practical unless the halftone black ink is printed on a surface that has been coated with a solid fluorescent ink. When using fluorescent ink to print text, text detection must be wide enough to facilitate reading.
The fluorescent ink should be leveled after printing. The flat ink film absorbs light, and the smooth ink film reflects light, preventing light from interacting with the fluorescent ink.
Fluorescent inks and phosphorescent inks are not radioactive and are harmless. However, it should be emphasized that self-emitting radioactive inks are also commonly used in screen printing, such as dial numbers. They are harmful to those who have no experience.
Fast-drying fluorescent inks Fast-drying fluorescent inks are inks produced by adding fluorescent pigments to fast-drying binders. The ink has good brightness and flexibility and is suitable for outdoor poster printing. Most of them are dried by evaporation. They must use painted stencils such as photographic type, water-based film type and knife-print stencil printing.
When the fluorescent ink is to be printed on a non-white surface, the surface should first be coated with a white base. The fast-drying fluorescent ink can be printed on the uncoated cloth label and can be printed on the surface of the pigment or nylon. When you do not know whether the ink is printed on the surface, you should do a test.
The lifetime of a fluorescent ink print product is determined by the ink and is not determined by the product itself. If fast-drying inks prevent direct sunlight, the life of printed products can be greatly improved. In the absence of light, fluorescent ink printing products can be preserved and maintain their original appearance.
The quick-drying ink takes about 30 minutes to dry naturally, and the mechanical drying can shorten the package time to 30 seconds to 2 minutes.
The preferred ventilation area is the conditions required for printing and drying. The drying process must be completed as quickly as possible to prevent blemishes from appearing during printing. A single-edged squeegee can produce an ink layer thickness of about 0.0025-0.0038 cm.
After printing, the screen can be cleaned with paint thinner, toluene, xylene, naphtha, or the manufacturer's recommended solvent. Indoor products can be screen printed with Number8XX-14XX; outdoor products can be screen printed with Number8XX-10XX.
After large-scale outdoor advertisements are made, it is recommended to use clean water, because the sticker absorbs ultraviolet rays and weakens the luster of the fluorescent ink.
Oil-Based Fluorescent Ink Oil-Based Fluorescent Inks If the ink can be printed better, the brightness can be maintained for the same time as the fast-drying ink, and outdoor prints can be kept for about 3-6 months. It takes 1-4 hours for the ink to dry by oxidative polymerization, which is mainly related to the printing substrate, ink layer thickness and workshop conditions. The drying of the ink can also be accelerated by gas heating, infrared rays, and spray drying agents. It is also possible to dry using a common ink drying method.
Oil-based fluorescent inks can be printed with most screen printing and can be printed on paper, wood, glass, metal, decals, and other surfaces with a white base coating. The ink can be printed using screens 8-16.
Oil-based fluorescent inks can be diluted with mineral spirits or the manufacturer's recommended solvent. The printing of letters should be in bold type with some contrast. Do not wrap the varnish overprinted on the ink. It will reduce the fluorescence effect.
Oil-based inks should not be mixed with fast-drying fluorescent inks. The use of oil-based fluorescent inks for wide sub-advertisement printing also requires the use of clean water to wash away stickers.
Luminescent fluorescent inks The fluorescent inks described above are all daylight fluorescent inks. The following describes fluorescent luminous inks. Luminescent fluorescent inks are best used in screen printing. The ink is sensitive to "noctilucent", sometimes the color of a large luminous fluorescent ink is called "invisible light" because it appears as neutral or nearly white under daylight or incandescent light. Most of the luminous type fluorescent inks are not different from ordinary inks during the day, but they can emit brilliant brilliance under a night light or near-ultraviolet light. The light source can be a mercury lamp or a luminous fluorescent lamp.
The biggest difference between the luminous fluorescent ink and the daylight fluorescent ink is that the latter can emit light in both day and night light, while the former only emits light under the night light.
The printing of luminous fluorescent inks is similar to the printing of daylight fluorescent inks. It cannot be mixed with ordinary inks, because in the nighttime, ordinary inks will affect the fluorescent effect of fluorescent inks.
In addition, the printer should follow the manufacturer's instructions when using it.
In summary, fluorescent inks play a crucial role in screen printing. Its use brings brilliant colors to screen printing. (Finish)
