Printability and Application of Solvent-Free Offset Printing Inks

With the improvement of environmental awareness and requirements, solvent-free inks and solvent-free inks have gradually been promoted. From the perspective of environmental factors, the United States, Japan, and other countries have formulated various regulations, such as reducing the emission of organic compounds into the atmosphere. Reducing the amount of IPA and alcohol used in the fountain solution, that is, controlling the physical health of IPA and organic matter-damaging people, China’s environmental protection awareness will increase with the entry of WTO and the establishment of OSHA, especially in the food packaging industry. The use of environmentally friendly non-toxic, non-aromatic ink printing food packaging, so according to market requirements, Tianjin Toyo Ink Co., Ltd. is also actively involved in environmental protection campaign, developed a non-toxic, non-polluting environmentally friendly ink. This article mainly discusses the characteristics, properties, and applications of TNV offset printing solventless inks:
First, the performance characteristics of TNV offset printing solventless ink:
1, the ink mineral oil content ≤ 1%; no solvent evaporated to the air, is the ideal environment-friendly products;
2, the product is non-toxic, low taste, is an ideal packaging and printing materials;
3, has good water resistance, ink balance and on-board stability, applicable to high-speed printing needs more than 10,000 printing per hour;
4, with excellent friction performance and drying performance, can be applied to ordinary coated paper printing, but also can be applied to high friction performance of matt paper printing.
5, has a good printability and transferability, clear printing points, bright color, high concentration, good gloss;
6, has a good vividness, transparency, gray balance, suitable for four-color version of overprint printing.
Second, TNV-type offset printing solvent-free ink color varieties TNV-yellow offset printing solvent-free ink TNV-red offset printing solvent-free ink TNV-blue offset printing solvent-free ink TNV-black offset printing solvent-free ink Third, TNV offset printing solvent-free ink characteristics Table 1

Fourth, TNV type offset printing solvent-free ink resistance value table 2

Fifth, the difference between solvent-free ink and general offset bright fast-drying ink:
1, the difference between solvent-free ink and general offset bright fast-drying ink (see Table 3)

2, the difference between solvent-free ink and general offset bright fast-drying ink (see Figure 1; omitted)
As can be seen from Figure 1, the solvent-free ink solvent volume and volatiles is almost zero, the film forming material is much higher than the general offset bright fast-drying ink 3, the difference between solvent-free ink and general offset bright fast-drying ink solvent-free ink printing No solvent evaporated to the atmosphere after the paper came, and no solvent penetrated into the paper. Almost all of the material was fixed on the surface of the paper, improving the friction resistance of the print.
Six, TNV type offset printing solvent-free ink in the printing application TNV offset printing solvent-free ink for offset printing four-color version of ink printing cylinder printing paper, white version of paper, matte paper (matt powder) and other printing substrates, printing advanced album, painting
