Application of environment-friendly gold and silver cardboard UV ink

With the rising global environmental protection demand, governments in the world have stricter controls over atmospheric organic volatiles and toxic substances than at any time before. They are known as environmental green technology D radiation curing technology (UV curing technology is one of them). In this climate, the benefits are shallow, and they have been given full attention and have achieved rapid development. UV light-curable inks are a type of environment-friendly ink developed rapidly in this environment. In the current prevalence of high-end tobacco and alcohol, pharmaceutical packaging, and promotional brochures, it has rapidly occupied the packaging and printing market with the advantages of instant curing (drying), free of volatile solvents, and simple and convenient application. UV screen printing inks can produce a variety of simulation art effects including UV frosting, UV refraction, UV wrinkles, UV crystal, UV foam and so on. On the surface of the substrate with metallic mirror gloss, the UV ink is printed on it by means of a screen printing process, and after curing by a UV curing machine, a unique visual effect is produced, as if the smooth metal surface was corroded and carved. Matte treatment, appear frosted, wrinkles, refraction, crystal, etc., it is elegant, dignified, luxurious.

The use of this type of ink is as follows:

(A) UV UV ink application features:

1. Instant curing (drying), high production efficiency;
2. Solvent-free discharge is safe and does not pollute the environment;
3, ink will not dry, will not block the network, it can be used very fine mesh print the best quality of the printed matter;
4, the ink concentration is stable, not because of the different concentrations of a color hue deviation;
5. Small size of printing machine and curing device saves space and saves investment;
6, suitable for temperature-sensitive printing materials;
7, high light cover ink and high light transparent ink, drying speed and bright colors;

(B) Printing effect and use of ink

UV matte ink:

This ink is divided into three types: coarse sand, medium sand and fine sand.

1, printing effect:

The products produced by the printing are dazzling in appearance and have a metallic texture. They can produce metal mirrors, etching, matte, matt, and multilayer colors.

2, the use of:

All kinds of gold and silver cardboard packaging products.

3, use method:

3.1 Over the net performance: use 180-250 mesh screen.
3.2 curing method: the use of UV curing machine (5.6kw × 2 lamps), photo-setting time of 3-5 seconds.
3.3 The ink needs to be stirred well before use, and high temperature and strong light should be avoided during use, and it should be closed immediately after use.
3.4 If the printing feels too much viscosity, it may be diluted in a suitable amount with a special sand thinner, but it must not be replaced by a solvent.

4, note:

4.1 This product is a UV-curable product and should be stored in a dark, cool, and clean place.

4.3 When using this product, there should be a good ventilation environment and a clean workplace.

UV Refractive ink:

1, printing effect

The products produced by printing have a strong refractive effect, bamboo mat effect, dewdrop effect, etc. The use of flat printing adds a three-dimensional sense.

2, the use of:

All kinds of gold and silver cardboard packaging products.

3, use method:

3.1 Over the net performance: Use special 350-420 mesh screen imported from Switzerland (made in Switzerland).
3.2 curing method: the use of UV curing machine (5.6kw × 2 lamps), photo-setting time of 3-5 seconds.
3.3 The ink needs to be stirred well before use, and high temperature and strong light should be avoided during use, and it should be closed immediately after use.
3.4 Precautions:
This product belongs to other light solid products, should be kept away from light in a cool and clean place.

UV crystal ink:

1, printing effect:

The products produced by the printing are of high quality, strong bulging, soft folding, good adhesion, and noble and beautiful surface.

2, the use of:

All kinds of gold and silver cardboard packaging products.

3, use method:

3.1 Over-net performance: The screen of 20-80 mesh is selected. At the same time, when making the screen, the net around the printing area is thickened so that the effect of bulging is more obvious.
3.2 curing method: use UV curing machine (5.6jwx2 lamps), light-setting time of 4-5 seconds.
3.3 The ink needs to be stirred well before use, and high temperature and strong light should be avoided during use, and it should be closed immediately after use.

4, note:

4.1 This product is UV light solid product, should be kept away from light in a cool and clean place.
4.2 If the viscosity is too high during use, special crystal thinner should be used. Otherwise, other diluents may be added at random, which may cause the solidified crystal ink to be whitened and become poor in transparency or stereoscopic effect.

UV foam ink

1, printing effect:

The unique foaming effect of the ink makes the printed thin ink layer thickened by UV curing, so that the three-dimensional effect is enhanced, and the surface of the printed material becomes gorgeous and peculiar.

2, the use of:

All kinds of gold and silver cardboard packaging products.

3, use method:

3.1 Over the net performance: use 180-250 mesh screen.
3.2 Curing method: Use UV curing machine (5.6kw × 2 lamps), photo-curing time 3-6 seconds.
3.3 The ink needs to be stirred well before use, and high temperature and strong light should be avoided during use, and it should be closed immediately after use.

4, Note s matters:

4.1 This product is UV light solid product, should be kept away from light in a cool and clean place.
4.2 The printing speed must be slower and the net distance should be larger than the original to avoid sticking the net.
4.3 The surface pattern is directly related to the printing speed and should be cured immediately after printing.

UV wrinkle ink:

1, printing effect:

The products produced by printing have the characteristics of high grade, strong three-dimensionality, transparent wrinkles, and metallic sense. After being printed on metal, imitation metal, composite mirror base material, it has a strong feeling of gold foil after uniform crumpling.

2, the use of:

All kinds of gold and silver cardboard packaging products.

3, use method:

3.1 Over the net performance: use 180-250 mesh screen.
3.2 Curing mode: First, the surface is shrunk by weak UV light to generate wrinkles, then the UV curing machine (5.6kw x 2 lamps) is used to cure the upper and lower layers, and the photosetting time is 6-9 seconds.
3.3 The ink needs to be stirred well before use, and high temperature and strong light should be avoided during use, and it should be closed immediately after use.

4, note:

4.1 This product is UV light solid product, should be kept away from light in a cool and clean place.
4.2 Pay attention to the cleanliness of the material surface before printing.
4.3 Adjust the speed of the light and solid machine as needed. The speed is too slow to produce wrinkles.
Solvent type cardboard packaging ink:
This type of ink high light cover ink and high light transparent ink.

1, printing effect:

3.4 The ink needs to be stirred well before use, and it should be closed immediately after use so as to avoid solvent evaporation.
3.5 Batch printing requires an additional amount of diluent.

4, note:

This product is a solvent-based ink, in the use and storage process should pay attention to fire, ventilation, away from fire.
With China's accession to the WTO and continuous deepening of reform and opening up, the export of products will certainly continue to increase. Major and medium-sized printing companies should make full use of their own advantages in technology, equipment, and capital, offset printing, flexo printing, gravure printing, and silk screen printing. Together, a large number of beautiful packaging products have been developed to make our country's export products marry.
