Some of the UV inks can meet the requirements of environmental protection, but most of the low-end and cheap ones cannot meet the requirements.

Printing is one of the four great inventions of ancient China. The invention of printing is the representative of the wisdom of the working people in ancient my country, so what exactly is printing?

In the production process of printed matter, there are usually five processes including selection or design of the original manuscript, original plate production, printing plate printing, printing, and post-press processing. People often refer to the design of the original manuscript, graphic information processing, and plate making collectively as prepress processing, and the process of transferring the ink on the printing plate to the substrate is called printing. The completion of such a printed matter requires prepress processing, printing, Post-press processing and other processes.

Recently, the fashion trend authority Pantone officially announced the representative color of 2023 - extraordinary magenta (Viva Magenta 18-1750), calling it "unconventional red in an unconventional era".

The basic principle and process of offset printing Offset printing is referred to as offset printing. The printing method of offset printing is to transfer the ink dipped on the rubber surface to the paper surface through a roller-type rubber stamp. Offset printing requires less ink and molds are less expensive to manufacture than gravure. In addition, since the offset printing surface is flat and there is no concave pattern, the pattern and pattern on the printed paper surface are also flat, there is no three-dimensional sense, and the anti-counterfeiting property is poor. Now let's understand the basic principles and processes of offset printing.

UV ink is also called UV-curable ink, which uses ultraviolet radiation of a certain wavelength to instantly turn liquid ink into a solid state through photochemical reaction. The viscosity of flexo UV inks ranges from 250 to 2000cP (25°C), which is much smaller than that of offset UV inks. At present, UV ink has entered a mature stage, and is recognized by the world as a pollution-free ink variety, and its safety has been recognized by the US Environmental Protection Agency. Flexo UV inks are general-purpose and can be used when printing various substrates such as plastic, aluminum foil, and paper. The printing quality of flexo UV ink is better than that of water-based ink and alcohol-soluble ink, so its development and application have been paid attention to by all aspects.
