Application and Advantages of LED Curing Lamps in the Printing Industry
As printing technology continues to evolve, traditional ultraviolet (UV) curing methods are increasingly being replaced by LED curing technology. LED curing lamps not only offer higher energy efficiency and longer service life, but also significantly reduce production costs and enhance print quality. This article explores the principles, types, advantages, application scenarios, and selection considerations of LED curing lamps in the printing field, helping readers gain an in-depth understanding of this modern curing technology. 1. Working Principle of LED Curing Lamps An LED curing lamp uses light-emitting diodes (LEDs) to emit specific wavelengths of ultraviolet light, which activate photoinitiators in printing inks or coatings. This activation triggers a rapid free-radical or cationic polymerization reaction, transforming the liquid ink or coating into a solid-state finish almost instantaneously. Compared to traditional mercury lamp curing, LED curing offers the following key features: 2. Major Types of LED Curing Lamps in Printing Depending on the printing method and the required curing width, LED curing lamps can be classified into several categories. Each category differs in irradiance (power density), lamp head width, cooling method, and applicable wavelength. The following are the most common types found in the printing industry: 3. Key Advantages of LED Curing Lamps ...
