UV LED Inks: The Future of Narrow-web Printing?
The future of narrow-web printing, or just a passing fad?
The choice of pigment will affect the choice of photoinitiators, as they will compete to absorb the UV light.
The difference with UV LED
The main difference between a standard mercury lamp and an LED lamp is the wavelengths emitted from the lamps that cause curing to take place.
A standard lamp has a broad spectra of wavelengths that spread from UV-A through UV-B and UV-C and include visible and infrared. This means that an ink or coating formulation will have a mixture of photoinitiators to allow the product to achieve optimum cure.
