UVLED curing ink process matters attention

UVLED curing ink through UVLED light curing machine, under the action of light initiator can complete curing in a short period of time.Necessary a variety of performance of printing ink can be made by a combination of oligomer and diluent.Careful selection of oligomer and diluent, will make the ink performance at the same time satisfy the requirement of printing process and printing ink film.But UVLED curing ink performance in certain circumstances affecting UVLED curing ink curing effect.
1, ink viscosity and yield modulus;
2, ink film flexibility;
3, pigment dispersion;
4, light fastness;
5, the curing speed.
6, ink transparency;
7, color sequence;
8, ink water balance (in lithographic system);
9, ink adhesion of base material;
10, print gloss;
11, further processing, such as a thermal performance;
12, punching and polishing;
13, ink viscosity;
14, ink film resistance (chemistry and physics);
