Application of UV ink in the most environmentally

Application of environment-friendly UV ink for gold and silver cardboard

with the increasing voice of global environmental protection, governments of various countries have stricter control over atmospheric organic volatiles and toxic substances than ever before, and radiation curing technology (UV curing technology is one of them), known as environmental green technology, has benefited a lot in this climate, received full attention, and achieved rapid development. UV curing ink is a kind of environmental friendly ink that has developed rapidly in this environment. In the current situation of high-end tobacco and alcohol, pharmaceutical packaging, brochures and other increasingly popular, it quickly occupied the packaging and printing market with the advantages of instant curing (drying), no volatile solvents, simple and convenient application. UV screen printing ink can produce a variety of simulation artistic effects, including UV sanding, UV refraction, UV wrinkles, UV crystal, UV foaming and so on. On the surface of the substrate with metallic specular gloss, UV ink is printed on it by means of silk printing process. After curing by UV curing machine, a unique visual effect is produced, as if the smooth metal surface has been corroded, carved and sanded, resulting in frosting, wrinkles, refraction, crystal, etc., which is elegant, solemn and luxurious

the use process of this kind of ink is as follows:

(I) characteristics of UV ink application:

3.3 the ink needs to be stirred evenly before use. During use, it should avoid high temperature and strong light. It should be sealed immediately after use

3.4 precautions:

this product is an additional light curing product, which should be stored in a cool and clean place away from light

uv crystal ink:

1. Printing effect:

the products produced by printing are of high quality, strong bulge, soft and folding resistant, good adhesion, and noble and gorgeous surface

2. Scope of use:

packaging products of all kinds of gold and silver cardboard

3. Usage:

3.1 over performance: select the target wire, and at the same time, when making the plate, thicken the area around the printing area to make the protruding effect more obvious

3.2 curing method: use ultraviolet curing machine (5.6jwx2 lamps), and the light curing time is seconds

3.3 the ink needs to be stirred evenly before use. During use, it should avoid high temperature and strong light. It should be sealed immediately after use

4. Precautions:

4.1 this product is a UV curing product and should be stored in a cool and clean place away from light

4.2 in the process of use, if the sensory viscosity is too large, special crystal diluent should be used, otherwise, adding other diluents at will may cause the solidified crystal ink to whiten and become less transparent or stereoscopic

uv foaming ink

1. Printing effect:

the unique foaming effect of the ink makes the thin ink layer printed thicker after UV curing, enhances the three-dimensional sense, and makes the surface of the printed matter gorgeous and strange

2. Scope of use:

packaging products of all kinds of gold and silver cardboard

3. Usage:

3.1 over performance: choose mesh wire
