“UV LED lamps are rapidly dominating the UV curable coating and printing market now, with its benefits of low heat generation, instant start-up and shut-down, longer lifetime, low consumption of energy and others than Mercury UV bulbs. TOPAZ UV LED inks have been specifically formulated to cure at 395 nanometers (nm). In general, UV-LED systems have a tolerance range of +/-5 nm and an nm output curve that is relatively narrow but spans approximately +/- 15 nm. The initiators selected for UV-LED inks target this range, but are also reactive outside this range. This means that UV-LED inks should be reactive to both UV-LED and mercury vapor curing systems. This may vary to some degree depending on the specific ink’s color and pigment load.
TOPAZET INSTANT UV LED LAMP is specially designed to control frequency and power differently in each section of single lamp. It helps optimization of curing condition and special effect presentation like selective matte or glossy surface.”
