Dripp / Hybrid effect is widely used in offset printing. This effect is achieved due to the reaction of gloss uv and conventional matt ink. The same can now be achieved through uv screen printing by two process. In the first process a full coat of gloss uv is given and for the second process, FM screen is prepared (where the effect is desired) and printed with dripp ink. Though best result is obtained on laminated foils, other materials like laminated boards, artcard, pvc etc can also be explored.
