The concept of UV curing includes the use of energy to change the ink from the liquid to the solid phase of the solid state. Or in another way, the light (energy) is manipulated to penetrate the thick pigment ink film, which is actually designed to prevent light penetration. Ultraviolet radiation is part of the spectrum of electromagnetic radiation. It is adjacent to the short wave part of the flx100 UV LED editedof visible light to reach ionizing radiation. The ultraviolet band itself is divided into discrete fields such as UVA long wave radiation, and UVC short wave radiation in ultraviolet. The treatment includes the cross polymerization of photosensitive materials, which can be inks and adhesives or coatings, generally in the ultraviolet long UV-A part of the bandwidth. With the passage of time, UV curing has been favored by many people. UV solidified products look good, many customers admire the high gloss level and the anti wear of UV products. The features of a printer, such as the fact that the ink is kept open, do not dry in the pot. Ultraviolet light began its printing in 1970s, but it took time to solve a lot of problems, especially the problem of managing heat. The mercury vapor lamp, such as the best production of about 365nm, also sends out infrared heat (energy), causing the thermosensitive substrate.

To be sure, many problems related to the development of UV technology have been basically solved through solving the problems and improving existing technologies or developing new methods. One of the latest and exciting developments is UVLED, which extends the possibility of application, provides production efficiency, and many other sides. There are many benefits for driving companies to use UV LED. LED technology is ozone and mercury free, which makes the environment more friendly. Ultraviolet LED uses small input power units, and provides instant on / off capability. They need less maintenance. It is reported that using less than 50% of the energy of ordinary mercury lamp. As printers, converters, or other manufacturers produce less heat, it is now possible to run some extensible films and special materials.

A compact LED (light emitting diode) UV curing system using LED to optimize flexographic ink can now be selected from RK printing and coating company, and can be integrated with flexiproof to select UV LED. LED ultraviolet lamps provide tailored output at important 385nm or 395nm wavelengths.
The possibility of ultraviolet extension. For example, in prototype or trial, such as flexiproof makes it possible to create an accurate prototype that does not take the field of outsourcing by line or without recourse. Because LED ultraviolet proof is flexible, it can be printed directly to the base board and cure the inline customer "concept verification" is easier and faster.

RK's Tom Kerchiss points out that UV light emitting diodes are specifically targeted at a set of nanoscale wavelengths. Therefore, a double color mercury vapor lamp will be provided to allow flexiproof UV to be accommodated in a wide range of substrates.
The purpose of flexiproof UV and new variety flexiproof LED UV is to make producers and flexo UV ink color and print users solve the problems of communication process, including color matching, printability, gloss, abrasion and chemical resistance, and so on. The printing and online highlights of the UV - solidified pinhole, etc., make a quick commitment to corrective actions.
