The monomer in the ink is liquid in liquidity before the ink is cured. The amount of change causes changes in the degree of drilling of the ink and changes in fluidity and affects ink solidification. The reduction in the amount of monomer during the printing process depends mainly on the ability of the rubber roller to resist monomer penetration. Poor rubber rollers, a large amount of monomer absorption affects the normal use of the rubber roller. Shorter service life of the rubber roller will affect the whole process of printing.
If the rubber roller is not strong enough to resist monomer, the new rubber roller will absorb a large amount of monomers in the initial stage, so that the monomer of the ink is significantly reduced, resulting in dryness, drilling, and inadaction of the ink. The operator must first start the ink for a period of time. The normal printing can only be carried out as the rubber roller absorbs the monomer saturation. Poor rubber roller, when the new roller is on the machine, it needs to be evenly inked before it can be printed normally.
After the monomer is saturated, the rubber roller rises with the temperature during the printing process. In the short term, the surface of the vitrified film on the surface of the vitrified film can not be used normally, and the life of the rubber roller is shortened. The monomer reduction of the ink directly destroys the fluidity of the ink. The ink is drilled, not the ink is not good, the reason is the quality of the rubber roller.
