What are the drying methods of ink?

   Ink drying methods can be divided into natural drying, heating drying,

ultraviolet drying, electron beam drying, infrared drying, microwave drying

and other forms. In addition to the above drying methods, it can also be

divided into physical drying and chemical drying according to the ink resin

contained in the ink. Secondly, according to the different properties of the ink,

it can be divided into osmotic drying, oxidative conjunctival drying, volatile

drying and other forms. The drying forms of inks with special properties

include photopolymerization drying and ultraviolet drying. Most inks usually

only use one drying method, but some inks are dominated by a certain drying

form during the drying process, accompanied by others.

   In general, volatile drying inks and water-based inks, oxidative polymerization

inks, and two-liquid reactive inks are dried naturally, hot and cold air or infrared

radiation. Heat-curable inks are dried by infrared radiation. UV-curable inks are

dried using ultraviolet radiation. Which drying method to use in actual printing

production should be selected according to the actual conditions such as the

ink used, the drying equipment, and the site.
