Matching requirements for UV inks when applied to different printed products
UV ink is a common environmentally friendly ink, its application involves the printing of tobacco, wine, food and other packaging, the application is very wide. It is worth noting that we must consider the compatibility of UV ink in printing construction, not only the physical properties of the printed product, post-processing requirements, application direction, industry environmental requirements are very well understood, but also take into account the conditions of the printing process, the actual conditions of the printing substrate, etc., in order to choose the UV ink that is applicable and compatible with it, in order to print a beautiful print that meets the requirements. Here we will talk about the following aspects of UV inks in the printing of the match.
First, UV ink shall meet the environmental requirements of the target product industry.
UV ink is widely used in tobacco, wine, cosmetics, electronics, food and pharmaceuticals and other industries packaging and trademark printing, in each of the different industries there are relevant industry regulations and environmental requirements, the ink selected must match the relevant industry regulations and environmental requirements of the target product. For example, in the electrical and electronic industry, halogen will reduce the electrical properties of the products after welding and corrosive, and electronic waste containing halogen compounds, plastic products after burning, easy to produce dioxin-like compounds, through bioaccumulation and health hazards, so the printing products used in the electrical and electronic industry must meet the IEC 61249-2-21: 2003 international halogen-free standards.
Second, the UV ink and printing substrate matching.
Common printing substrates are paper, film, fabric, metal, ceramics, etc.. Different printing substrates, due to its material structure, surface treatment is different, making the printing substrate surface tension is different, the same ink in different printing substrates will show different adhesion. For printing products, adhesion is one of the basic conditions that need to be met. In order to ensure that the ink has sufficient adhesion on the printing substrate, it is necessary to choose the UV offset printing ink that matches the printing substrate. Ink and printing substrate matching, not only in the ink on the printing substrate adhesion, and ink and printing substrate chemical properties match, such as ink on the printing substrate erosion and bite the bottom of the phenomenon, so that the ink color phase changes, inconsistent color printing; film printing substrate due to the addition of some of the chemical substances precipitated, the precipitation of chemical substances on the ink film layer corrosion, the return of sticky phenomenon.
Third, the UV printing ink and product application environment matching.
Printing products have different application environments, the ink will have different requirements, such as printing on the card ink, its surface hardness should be high, good friction resistance, otherwise the printed cards are prone to rubbing, damage; and in cosmetics packaging, in order to attract the attention of consumers to the goods, you need to choose beautiful colors, should not fade, excellent light resistance of the ink. Tests have proved that the formula added anti-yellowing agent BETTERSOL 1930 can increase the light resistance of the ink, slowing down the fading phenomenon of the ink. Poor light resistance of the ink printing products placed for a long time, the product is prone to fading phenomenon, which is not only detrimental to the beauty of the goods, and looks old sense, reducing consumer goodwill and attractiveness of the goods.
Fourth, the UV ink and printing post-processing matching .
After the printing of various products after the printing process is different, the corresponding requirements for the performance of the ink will be different. Such as die-cutting, creasing and other post-printing process, in order to avoid the processing of burst color, you need to choose a good flexibility ink; hot stamping, blistering and other post-printing processes need to choose a good flexibility, high surface tension ink, otherwise there will be bad stamping and blister not on the phenomenon.
