Imitation of metal etching printing products, in the visual effect of metal etching.

In order to achieve the above effect, the substrate surface should have mirror gloss. In the substrate with transparent ink printing into concave ink coating, the formation of ground-glass rough surface, with a strong contrast of rough surface combination, so that the printing surface is concave, the mirror produces a convex printing effect. The stronger the contrast, the better the imitation etching. Concave and convex effect and the thickness of the ink film

The proportion. The ink contains high solid composition, if the use of low mesh plate, the effect will be better.

The technique initially used a gelatinous ink with an acrylic emulsion (50% solid), which was then dried and heat treated at 180 ° C. So substrate is limited to heat resistant metal and glass, can not use hard plastics and paper. Because of the use of acrylic emulsion and other viscous gel ink, as well as the temperature in the operation and other reasons, the stability of ink viscosity is very poor, the quality of the product fluctuates greatly.

Since the use of uv drying ink in screen printing, printing technology, techniques have great flexibility. Uv ink is 100% curing type, uv irradiation 3 ~ 5s ink can be hardened, during which the surface temperature is about 100℃. If the use of water-cooled UV irradiation machine, the temperature can be reduced to about 60℃, so that the type of substrate will increase, can be printed on aluminum foil paper with mirror gloss, evaporation paper, evaporation vinyl chloride film, polyester film and other materials.

At present, the market appears a variety of ultraviolet drying imitation metal etching special ink, can be used for this kind of printing. Suzhou silk screen printing ink
