What is fluorescent ink? Introduction included.

I. Printing methods:

Fluorescent ink is typically printed using one of four methods: screen printing, offset printing, transfer printing, or pad printing. It comes in four colors: red, yellow, blue, and green, and can be printed alone or in combination on common substrates such as paper, fabric, metal, ceramics, and plastic.

II. Applications of fluorescent ink:

Fluorescent ink is widely used in fields such as tickets, certificates, labels, packaging, and anti-counterfeiting for various high-end products.

III. Precautions:

1. When using fluorescent ink, it is important to prevent mixing colored ink with colorless fluorescent ink, as this can affect the invisible effect. Therefore, it is necessary to thoroughly clean the old ink roller and plate, or to use a new ink roller with a new plate.
2. When used on objects with chemicals on their surface, care should be taken, as if the chemical reacts with the fluorescent ink, it can gradually diminish the fluorescent effect.
3. The ink state varies depending on the printing method. Screen printing ink is in a semi-transparent liquid state, while offset printing ink is a yellowish paste.
4. The printing area of the ink varies depending on the method of use. The ink consists of a single component and has a fineness of about 5 microns.
5. Fluorescent ink can be dried using self-drying or UV baking methods depending on the printing method used.
