Green and Environmentally Friendly LED UV Curing Machines

Reasons for choosing UVLED curing machines in the printing industry./

As a new type of curing method, UVLED curing machine has better curing effect and higher adaptability for UV coatings such as UV ink and UV varnish, and is a good helper for improving production efficiency and yield in the printing industry. So why does the printing industry generally choose UVLED curing machines for curing? What is the reason why it can replace UV mercury lamps? 

1、 Improve product quality

UV printing has good printability for most substrates. UV printed products have clear dot patterns, good tone reproduction, bright and glossy ink colors, and high printing consistency. At the same time, because the curing process of UVLED is a photochemical reaction process, both the ink layer and the varnish layer have the advantages of strong adhesion, strong durability, water resistance, chemical corrosion resistance, wear resistance, aging resistance, etc.

2、 Improve production efficiency and economic benefits

Drying is carried out through a UVLED curing machine, which does not require a heat source, does not contain solvents, and has a very short curing time. Most UV processes can achieve a line speed of 400 meters per minute, greatly improving production efficiency. After printing with UV ink, it is processed by a UV polishing machine to obtain printed products with high glossiness and a smooth, uniform and consistent surface. After the machine is connected for polishing, packaging processing techniques such as die-cutting, indentation, gluing, and hot stamping can be immediately completed, which is very beneficial for the development of high-speed printing. High speed means that it can reduce the storage costs and financial pressure of raw materials and finished products. At the same time, due to the low energy consumption of UVLED curing machines, production costs are greatly reduced.

3、 Meets environmental requirements

The curing system of the UVLED curing machine combined with UV ink is a solvent-free system, which is a 100% solvent-free formula and does not contain VOCs, which precisely meets today's environmental requirements. This is another important characteristic of UVLED curing, which does not or rarely emits volatile organic compounds during the curing process, and does not cause significant environmental pollution.

4、 Fast curing degree

UV ink will only dry under the irradiation of a UVLED curing machine. Even if the ink is stored in the ink hopper for a long time, its performance can remain stable and there will be no skin formation on the ink roller. Once exposed to ultraviolet radiation, the ink can instantly dry and generally only take 110 seconds to completely dry and fix on the surface of the substrate. Traditional thermosetting ink and single sheet offset printing ink may take several minutes or even days to completely dry. Therefore, using a UVLED curing machine combined with UV ink to print movable parts has a short delivery time and can be comparable to flexographic and gravure printing, greatly improving the production efficiency of printing.

The above is about the reasons why the printing industry chooses UVLED curing machines. After reading it, do you all know? I hope it is helpful to everyone.
