Compatibility Of UV Offset In Printing Compatibility Of UV Offset Printing Inks In Printing
- May 28, 2018 -

In the past, the application of UV offset printing technology in China was in a period of rapid development. At the same time, the demand for UV offset printing inks in the printing market also entered a period of rapid growth. In order to match with different substrates and printing processes, the requirements for UV offset printing inks from printing companies have also been increased, resulting in a variety of different ink formulations, each with different characteristics and characteristics, and stronger correspondence. Sexuality and specificity. Then, for printing companies, in order to meet national environmental protection requirements, print quality requirements, save time and money, and avoid unnecessary troubles, when selecting UV offset inks, we must consider its compatibility with a variety of factors. In the following, the author will discuss the matching of UV offset printing inks in printing with reference to practical cases for reference by those in the industry.

UV offset inks match the environmental requirements of the target application industry

UV offset printing inks are used in packaging and trademark printing in the tobacco, wine, cosmetics, electronic products, food, and pharmaceutical industries. In these different industries, there are different environmental regulations, and UV offset inks are used as prints. The essential part must be matched with the relevant industry regulations and environmental requirements of the target product before it can be put into use. For example, in the electronic product industry, halogens reduce the dielectric properties of electronic products after welding and cause corrosion, and electronic scraps and plastic products containing halogen compounds burn easily to produce dioxins, through bioaccumulation. It will cause harm to the environment and human health. Therefore, the printing ink products used in the electronic product industry must meet the requirements of the IEC 61249-2-21:2003 international halogen-free standard.

Case: A printing company mainly prints electronic tags. Previously, products of small batches of samples always exhibited excessive halogen content. After market investigation, the appropriate UV offset inks were selected (such as UVT-WL series of halogen-free inks produced by Haihui ), The printed product fully meets the standard requirements for halogen control in IEC 61249-2-21:2003 and meets customer requirements.

UV offset printing ink and product application direction matching

Different application directions of printed materials may also have different requirements for UV offset printing inks. For example, UV offset printing inks for card printing require high surface hardness and good abrasion resistance. Otherwise, printed card products are prone to scratching and surface damage. Such as quality issues; and in order to make cosmetics packaging quickly attract the attention of consumers, printing companies in the selection of UV offset inks, should consider the use of colorful, not fade, and excellent lightfastness of the product, otherwise the cosmetics packaging place a long time, Fading will appear on the surface, the appearance is no longer beautiful, it looks old, so that consumers' impression of the product is greatly reduced.

UV offset printing ink and printing substrate matching

At present, the main printing substrates include paper, films, fabrics, metals, and ceramics. Among them, commonly used printing papers include newsprint paper, offset paper, coated paper, aluminized paper, specialty paper, etc.; commonly used film materials include PVC, PE, PET, PP, OPP, ABS, PA and so on. Different printing substrates, due to their different material structures and surface treatments, will have different surface tensions, so the same ink will show different adhesiveness on the surface of different printing substrates. In order to ensure that the ink has sufficient adhesion on the surface of the printed substrate, the layer cannot be peeled off, and the UV offset ink that matches the printed substrate must be selected. Otherwise, quality problems will occur.
