Postpress hot stamping silver

From the process point of view, there may be: printing process of fluorescent coatings, common direct printing of fluorescent coatings and common coatings, direct printing of fluorescent coatings and reactive dyes, color discharge printing of reactive dyes, and printing and printing of turnips.

Factors that affect the fluorescence of daylight fluorescent coatings are:

1. The whiteness of printed fabric: The whiter the fabric, the brighter the fabric surface, the better the light reflection, the better the fluorescence degree, the fluorescence degree printed on the white cloth is better than the color cloth, and printed on the mercerized bleached poplin, the fluorescence degree. better;

2. Adhesive: The better the transparency of the adhesive after film formation, the better the fluorescence. In the molecular structure of adhesive components, the vibration of electrons and the vibration of electrons in the molecular structure of the fluorescent coating are compatible, and the fluorescence is relatively good;

3, the amount of fluorescent paint: the increase in the amount is conducive to the increase in the degree of fluorescence, but when the amount of fluorescent paint reaches 30%, i, the saturation of the fluorescence;

4, fight color: fluorescent paint, such as blending and common paint to adjust the color, the fluorescence will be greatly reduced.

Fluorescent printing process made of a variety of light products, absolutely safe for consumer goods, such as: clothing, shoes and hats, stationery, watches, switches, signs, fishing gear, crafts and sporting goods. And in the building decoration, transportation tools, military facilities, fire emergency systems such as: import and export signs, escape, lifeline instructions system has a good role.

Fluorescent printing is one of the traditional methods of textile printing. To further promote the printing of fluorescent coatings, efforts should also be made in the following aspects:

1. Improve the tinting strength of fluorescent paints. The current use of fluorescent paints is relatively high, and it is difficult to open the deep and shallow layers of printed patterns.

2. Continue to develop chromatograms for fluorescent coatings;

3, need to increase the degree of fluorescence, to solve the problem of the low degree of fluorescence of Royal Blue, Green, Ching Lin;

4, can develop fluorescent coatings for adhesives and thickeners to improve the print fastness and color brightness.

The flavor microcapsules, adhesive printing pastes and printing fabrics can be used with good compatibility. The printing paste is applied to the surface of the fabric by screen printing and then dried. It not only enables people to enjoy the beauty visually, but also enjoys pleasant satisfaction in the sense of smell. This product was initially used on calico and was popular with consumers and gradually developed into clothing, sheets, handkerchiefs, socks, and scarves. At present, the concept of fragrance printing has been promoted as “breathing printing” over time, because it is not just the effect of producing fragrance. It also contains breaths that produce a variety of nature. Such as forest atmosphere, pine scent and pea blossoms. The characteristics of these breaths are similar to those of nature, which gives people a feeling of physical and mental pleasure and return to nature.

The principle of the fragrance printing process is to use liquid fragrance or other organic solution, so that the flavor can be evenly mixed with the colored printing paste and fixed to the fabric by the effect of the binder in the coating. Due to the fact that the organic compounds contained in the fragrance are relatively volatile and chemically unstable compounds, the components of the fragrance are very complicated, and are easily volatile or degraded during use and storage. Therefore, the preservation and control of the use of fragrances has become a key issue for research and development. To protect fragrances from external environmental factors, to control or prolong their release period to achieve people's use of spices, the best way is to microencapsulate flavors. Microcapsule technology is a kind of solidification with a film-forming material. Or liquid coating technology to form fine particles.

Bronzing hot silver is a traditional means of framed and beautified. It is often used on many paper packages. Silk printing hot silver is a new type of technology. The principle is to add special chemical agents to the printing paste to make the flowers appear special. Beautiful gold and silver, long-lasting color, no fading, can be printed on many kinds of fabrics, the cost ratio is lower than the traditional technology, it is a very ideal printing decoration technology.

Crystal coating material gold printing paste with special crystal as the core, covering the brightness enhancement layer, titanium film layer and metallic luster deposition layer, can be exposed to the air in long-term will not be dark, with good weather resistance and high temperature resistance , feel better after printing. The silver printing paste using the mica-coated body has improved the durability of the ink. The mica-coated silver-printing paste is basically similar to the mica titanium pearlescent printing paste in that the temperature during the coating of the titanium film continues to increase. , can get the same light as silver, titanium coating different thickness, able to diffract different colors of silver light. Mica-coated silver printing pastes have good compatibility with chemicals. After being printed on fabrics, the fastness is also good and long-lasting silver rays can be maintained.
