Technical methods and standards for making fluorescent inks

I found a lot of The printing masters believe that fluorescent inks with higher pigment content often have problems of ink accumulation, emulsification, and two to three times of printing to barely achieve the desired hue and fluorescence. In fact, high-quality fluorescent inks can be close to the general four-color inks in terms of printing performance. The main reason for the above misunderstandings is that the supply of high-quality fluorescent inks in the market is relatively small and the selling price is relatively high, which makes the printing enterprise buyers usually choose lower. Price product. Here, I would like to share with readers the technical methods and standards for making fluorescent inks, in order to help readers know about fluorescent inks and have some choices when choosing.

1. Hue and fluorescence standards of fluorescent inks

Generally, domestic and foreign ink factories use imported fluorescent inks as raw materials. The hue and fluorescence standards are generally based on the PMS 801-807 number on the Pantone. Therefore, the fluorescent ink used in the production of fluorescent inks can be consistent with the requirements of the "PANTONE" book under both standard and UV light sources, both in hue and in fluorescence. At the same time, all ink factories that use the "PANTONE" number must send their inks to the United States' Pantone Company. After passing the certification of Pantone, they can be sold under the name and number of "Pantong". In addition, most designers and print buyers also use the standards represented by the numbers in the “PANTONE” book to design or serve as the receiving standard. Therefore, the purchase of non-standard fluorescent ink not only affects its printing performance, but also loses orders because it cannot meet the hue and fluorescence required by the printing buyer.

2. Consequences of insufficient fluorescent ink concentration

High-quality fluorescent inks can reach the standard when the fluorescent ink content is 65% to 75%, so the price is high. When using a fluorescent ink with a low price and a low fluorescent ink content, it takes two to three times to be able to barely meet the standard, which is time consuming.
