UV LED Inks: The Future of Narrow-web Printing?

An LED lamp has a very narrow wavelength, with a peak around 395 nm, although LED lamps are available with alternative wavelength diodes including 375 nm, 385 nm, 405 nm, and 410 nm (±20 nm). Therefore the ink and coating technology must be reformulated so that the reactivity and cure results are similar, but with the high-intensity LED output.
