E*n Printer Upgrades Solution

I. Introduction to UV LED Bands (Application in Printer Modification)

For the modification of Epson printers, UV LEDs in the UVA (320 - 400nm) and UVB (280 - 320nm) bands are mainly applied.

The UVA band can quickly evaporate and dry the ink solvent, speeding up the printing process. It also enables the ink to adhere better to the medium and enhances printing quality, making the colors vivid and lasting. The UVB band is crucial in special materials or high-durability printing tasks. It can activate the photoinitiator in the ink, triggering a cross-linking reaction of polymers and enhancing the hardness and wear resistance of the ink. It is suitable for scenarios such as outdoor advertising and product labels.

II. Product Overview

This modification solution upgrades Epson printers to devices with UV LED curing functions. Combining its original high-precision printing technology and the characteristics of UV LEDs, it can cure various UV inks. It is compatible with multiple printing materials and can precisely control the illumination intensity and wavelength of UV LEDs to meet diverse printing needs.

III. Solution Principle

1.UV LED curing principle: UV LED lights are installed near the print head or under the printing platform. When printing, as the ink is ejected, the UV LEDs emit ultraviolet rays in the UVA and UVB bands. The photoinitiator in the ink absorbs energy and generates free radicals, triggering a polymerization reaction in the ink to achieve rapid curing.

2.Collaborative principle of modification: Combine the UV LED system with the original control system of the printer. Through circuit modification and software programming, control the UV LED. At the same time, install a heat dissipation device to ensure stable operation.
