Fluorescent screen printing ink, scope of application and matters needing attention
Fluorescent ink is suitable for printing paper and vinyl film, etc.Due to inorganic fluorescent material is made of crystal shine, if stress can make crystal break, so that the luminous intensity is reduced, so you don't normally use letterpress, very suitable for screen printing and gravure.Most of the rheological properties of fluorescent ink in plastic flow, viscosity is small, this feature determines its printing with ordinary ink printing process is very different.In gravure and screen printing, in addition to pay attention to the character of viscosity, connection material, dry, also note the printing pressure adjustment, does not affect the printing effect to make the printing pressure is too large.In the screen printing, attention should be paid to the following:

(1) the fluorescent ink suitable for below 200 mesh screen;

(2) the amount of inking print in 50 ~ 60 g / ㎡, the hair color and light fastness is ideal;

(3) in the substrates are transparent objects, you should print a white ink, which can improve the effect of fluorescence.
